Mesoporous Titanium Oxide Based
Anodes for Batteries
Technology Summary
High power and high energy density are essential to batteries or electric vehicles,
stationary energy storage systems or solar and wind energy, and vehicle to grid and
similar smart grid applications. Because conventional lithium ion batteries are inadequate
to meet these needs, and because many o the current perormance barriers are
materials-related, researchers at ORNL are concentrating eorts on advanced materials
and processing methods or next generation lithium ion batteries that will meet high
power–high energy density needs.
Titanium dioxide nanomaterials have been widely investigated as lithium ion battery
anode materials due to their advantages in terms o cost, saety, and rate capability. In
particular, TiO2-B has been investigated because o its avorable channel structure, which
results in ast charge-discharge capability. However, TiO2-B also has some disadvantages
such as poor electronic conduction, loss o particle connection during cycling, and low
packing density. Researchers at ORNL developed mesoporous TiO2-B powders that
overcome these shortcomings while maintaining the advantages o TiO2 nanomaterials.
ORNL’s mesoporous TiO2-B can increase power, energy density, and saety while
dramatically reducing charge time (charging to 65% o ull capacity in just 6 minutes
or 45% in 1 minute). In addition, the researchers have developed a scalable, economic
aerosol pyrolysis technique to make high quality TiO2-B powders with consistent,
reproducible phase content, particle morphology, size distribution, and microstructure.
Despite the need, ew viable new cathode materials have emerged. To address this, ORNL
researchers are looking at ways to improve existing cathode materials and cathodes
in addition to new cathode materials. In one application, the conductivity o ternary
metal cathode materials was enhanced (up to 625 W/kg) through surace and bulk
modifcation. In two other applications, replacements were developed or lithium-cobalt
oxide cathodes, high perorming but expensive and potentially hazardous. In the frst,
spinel cathodes made with manganese, a great low cost substitute or cobalt, were
modifed with metal oxide/metal nitride coatings to provide high capacity, continuous
chemical stability, improved conductivity, and reduced irreversible capacity loss. In the
second, the rate capability and overall electrochemical perormance o LiFePO4 cathodes
were boosted through surace modifcation with nitrogen-doped carbon layers and
preparation o smaller, more homogeneous particles, leading to shorter lithium diusion
pathways in the fnished cathodes and thus improved electroactivity and rate capability.
Advantages • Greater saety
• Fast charging
• Improved perormance
• Reduced costs
Potential Applications
• Electric vehicles and hybrid electric vehicles
• Stationary storage or renewable energy
sources such as wind turbines
• Smart grid

Thin Carbon Films for
Batteries
Technology Summary
Researchers at ORNL have invented a more eective method o preparing
thin carbons lms, a material that has become increasing important to the
development o energy-saving storage batteries. Using this new method, it
is possible to produce a very resilient, thermally stable porous carbon lm
characterized by a highly ordered arrangement o uniormly sized pores.
Conventional polymer carbon precursors are typically in solid orm and must rst
be dissolved in a solvent. This is a time-consuming process that can introduce
imperections into the carbon lm. Another drawback is that the high viscosity o
polymer precursors makes it difcult to apply them as a coating on a substrate.
Non-polymer liquid molecules can be easily applied, but they are also highly
volatile and, in the end, yield little or no carbon.
The new ORNL method eliminates these problems by using an ionic liquid
precursor that contains at least one unsaturated carbon–nitrogen bond in either
or both o the cationic and anionic portions o the ionic liquid. The extensive
cross linking that takes place between carbon precursor molecules during heat
processing ensures that the method produces porous carbon lms with a highly
ordered arrangement o pores and/or highly uniorm pore size. These ionic liquid,
non-polymer molecules possess both the low vapor pressures and the high char
ormation capabilities o polymers, under typical carbonization conditions.
Advantages
• Non-polymer ionic liquid molecules can be
used as carbon precursors
• Ionic liquid precursors exhibit the same low
vapor pressures and high char ormation
capabilities o polymers, without the time-
intensive processing
• Porous, thin carbon lms produced have a
highly ordered arrangement o pores and/or
highly uniorm pore size
Potential Applications
• Separations
• Catalysis • Battery components or energy storage

Nanoporous Membrane for Water Recovery from
Gasoline Exhaust
Technology Summary
A vast amount o energy is wasted in the United States rom the exhaust/euent
streams o an estimated 163,000 commercial and industrial boilers. Much o this energy
could be recovered by sieving the streams through inorganic membranes eaturing
nano-sized pore technology. The estimated savings by 2030 or energy recovered rom
<1000 bark boilers and paper machine exhaust hoods is about 1.3 tera-Btu. A cumula-
tive savings o 360 tera-Btu could be recovered rom heat currently lost to the environ-
ment, i the technology was implemented throughout the United States.
Researchers at ORNL have developed an inorganic membrane abrication technologythat would permit the recovery o such previously wasted energy rom relatively low
temperature (<100°C) exhaust/euent streams. The process involves removing moisture
rom the exhaust streams and recovering the latent heat when water condenses in the
membrane. The heat recovered could serve to preheat the boiler eed water, thus providing
an energy savings.
The membrane developed by the researchers at ORNL eatures pore diameters as small
as 0.5 nm to 20,000 nm, and testing has shown eectiveness at many scales. The suppor t
structure and layer or the membrane can be made o a variety o metals and ceramics.
Thin ceramic separation layers, or example, allow a high ow o gases through the small
pore membranes (<100 nm). Porous metal layers applied to tubular porous stainless steel
supports yield lters with pore sizes rom 0.05 to 1 μm. Their mechanical, thermal, and
chemical stability can be tailored by a choice o materials.
As gases and euent are transported via molecular diusion, these membranes separateconstituents rom the ow by Knudsen diusion, molecular sieving, capillary condensation,
surace ow, or a combination o these transport mechanisms. The key to the design is
permeance and separation actors: a balance between the volumetric ow rate per unit
surace, per unit o transmembrane pressure, and the ratio o ow o two gases in a binary
gas mix.
The membranes have shown eectiveness in using molecular sieving to separate hydrogen
rom coal-derived synthesis gas and rom renery gases. They can separate carbon dioxide,
a component o many gas streams, including synthesis gas and ue gas, by Knudsen
diusion, molecular sieving, surace ow, or a combination o these. Carbon dioxide can be
separated rom the gas stream as the permeate or as the rejected component, by choosing
a membrane with the proper pore size and operating temperature.
Advantages The inorganic membranes can improve
energy recovery rom low temperature, moist
industrial process streams. Metallic-based
membranes are capable o perorming in exhaus
streams containing particulates and gaseous
contaminants. Membranes can be operated
at high temperatures and pressures. Materials
can be selected to provide long lie in corrosive
environments. Boiler efciency can be improved
rom 87% to 94%.
Potential Applications
Potential applications are in gas separation, watepurication, energy and water recovery rom
industrial process streams, and solid oxide uel cel

Catalytic Conversion of Bio-
Alcohols to Hydrocarbons
Technology Summary
A method or catalytically converting an alcohol to a hydrocarbon without
requiring puried or concentrated alcohol was invented by ORNL researchers. This
approach can be used or relatively dilute bio-mass produced alcohols, such as
those ound in a biomass ermentation reactor.
Conventional biomass to hydrocarbon conversion is generally not commercially
easible, due to costs o the conversion process. This invention oers a method or
catalytic conversion o biomass-derived alcohols or mixtures o alcohols to olens
or parafns at relatively low temperatures. These hydrocarbons can then be added
to a variety o transportation uels without the need to make expensive changes to
vehicles. Another critical advantage o this method is that the conversion can occur
in the presence o water, even at dilute conditions.
Advantages
• Direct catalytic conversion o an aqueous
product stream o biomass to hydrocarbons
• Reduction or elimination o distillation energy
costs associated with hydrocarbon production
• Expansion o traditional ethanol ermentation
into ungible uel applications
Potential Applications
• Hydrocarbon products as transportation uel
• Alternate renewable source o raw materials
or the chemical industry

Lignin-based Oxidized Fibers for
Flame Retardancy
Technology Summary
Most ame retardant abrics on the market today are produced rom high density PAN
based fbers made by an oxidation process. Because o the time and expense involved in
making these fbers, there is a continuing need to fnd new methods and new materials
with improved ame retardancy and acceptable—and adjustable—mechanical
properties. ORNL researchers have discovered an oxidation method that is 3 to 4 times
aster than conventional methods and a way to substitute lower cost polyolefns or PAN.
Carbon fber reinorced composites are stronger and lighter than steel, so they can
replace steel and other metals in automotive and aircrat parts, thus saving weight and
uel. Most carbon fbers are produced rom textile polyacrylonitrile (PAN) precursorfbers, which are made in an expensive multistep process that uses toxic solvents. ORNL
researchers have developed a process that will enable use o lower cost polyolefns to
produce carbon fbers. In addition to cost advantages, polyolefns have a higher potential
carbon yield than PAN; are produced by melt spinning, which doesn’t use toxic solvents
and is aster than the process used to make PAN; and are produced commercially in the
United States (PAN fbers are not). The one stumbling block to their use is stabilization
beore carbonization. Current processes take up to 12 hours and are not amenable to
most industrial settings. ORNL researchers have developed a new stabilization process
that takes only 1 hour. This stabilization step uses standard, low cost chemicals and
industrial methods and is even aster than the stabilization processes used or PAN fbers.
Some o the resulting fbers exhibit ame retardant properties and could be used to
produce ame retardant abric in addition to carbon fber reinorced composites.
ORNL researchers used their experience with plasma processing techniques to developan advanced plasma based oxidation process in which rapid and aggressive oxidizing
conditions are used to create an oxidized PAN fber (OPF) possessing a high degree o
crosslinking and corresponding density. (Typically, an increase in the density o a PAN
fber increases its ame retardant properties.) One key aspect o the process is the use
o reactive oxidizing species, which ensures rapid, simultaneous oxidation o all parts o
the fber, including the core. The OPF produced by this method, while not suitable or
carbon fber production, possesses exceptional ame retardant properties along with
advantageous physical and mechanical properties, such as resistance to chemical attack,
that result in improved integrity during use. In addition, the process conditions can be
adjusted to urther fne-tune the mechanical properties o OPFs.
Advantages • High carbon yield
• Low raw material cost (recycled materials
could be used, urther reducing costs)
• Short stabilization time
• Enhanced physical and mechanical properties
• Superior ame retardant properties
• Minimal use o corrosive/toxic solvents
• Flexible, industry riendly
• Cost-eective
Potential Applications
• Flame retardant materials • Asbestos replacements
• Fiber reinorced composites
• Automotive and aircrat industries

Self-Cleaning Prosthetic
Skin
Technology Summary
Articial limbs help to restore normal unction to amputees. Surace materials or
prostheses need to look realistic, hold up to exposure, and mimic skin. ORNL scientists
combined superhydrophobic polymer inventions with carbon nanotubes to create a
sel-cleaning skin-like surace material with the ability to transmit heat. This material
provides an improved external covering or mechanical prosthetics.
The addition o embedded carbon nanotubes makes the ORNL prosthetic skin
tougher, stronger, and more durable than conventional materials. This is a signicant
improvement over prosthetic materials that tend to wrinkle or distort when stretched
or compressed. The vertically aligned carbon nanotubes help the surace material
transmit heat much more easily than untreated polymers. In addition, the material
can be adjusted or color and skin smoothness, which is highly desirable or aesthetic
appeal.
To increase the superhydrophic properties o the material, the carbon nanotubes may
be exposed to a high temperature annealing process. The material is also useul or
orming molded shapes that include nano-patterned arrays.
Advantages• Tougher, stronger, and more durable than
conventional materials
• Thermal conductivity
• Improved skin color and smoothness options
Potential Applications
• Prosthetic limbs
• Molds with skin-like requirements

Digital 3D Holographic Microscopy
Technology Summary
An optical system capable o reproducing three- dimensional images was invented at
ORNL. This system can detect height changes o a ew nanometers or less and render
clear, single shot images. These types o precise, high speed measurements are impor-
tant or a variety o nanoscience applications.
Imaging oers a compelling alternative to convention scanning because it is aster and
does not require a contact point. This invention uses a three wavelength approach
to address the challenge o suciently high resolution imaging over time. The device
quantitatively determines the position o points on or within an object and can update
images as the same rate data is received or match a user’s perception o real time.

Technology SummaryORNL researchers have developed an implantable,
remotely activated, microvalve or controlling the release
and movement o uids and physiological materials in the
human body.
The controlled release o enzymes and the ow o
blood and other biological uids in the human body
are essential or primary physiological unctions. Many
disease conditions—or example, urinary incontinence,
diabetes, and hydrocephalus to name just a ew—are
attributable to the ailure o natural mechanisms to
regulate the ow o biological uids in the body. Prophylaxis with articial valves and delivery systems is a logical solution; however,
most such systems are not easily controllable once inside the body, not bidirectional, and/or not small enough to be implanted whereneeded. The ORN L microvalve system meets all these criteria and more.
The ORNL device includes a thermally actuated valve that, once in the body, can be clinically manipulated wirelessly and nonsurgically.
The valve is implemented on polyimide -coated, used silica capillary tubing serving both as the struc tural ow element and as the
support structure or balloon-based expansion and retention. The key to the system is a thermally responsive polymer within a
75- to 300-micron diameter restricted ow element o the capillary tube. Under normal physiological conditions, the thermally actuated
polymer exists as an expanded hydrogel, eectively restricting the uidic path. The hydrogel can be heated via wireless radio requency
(RF) coupling to elevate the temperature o the polymer, inducing valve opening via hydrophobic collapse and shrinkage o the
polymer. Heating is achieved with a physical vapor deposited thin-lm metal resistive heater or a resistive wire wrapped around the
tube containing the valve material. Following removal o RF excitation, the polymer reverts to a hydrophilic, expanded hydrogel thereby
reversibly closing to again interrupt ow. A balloon insert is used both to immobilize the valve in the desired passageway/position and
to provide thermal insulation. Additional instrumentation to measure and transmit inormation on pressure, volume, and temperature
may be incorporated in the device, ensuring proper unction. The complete system is small enough to be inserted with a catheter.

Magnetic Filtration Process
Technology Summary
ORNL researchers developed a new method or ltering materials and managing
wastewater. This invention oers an integrated, intensied process to handle
organic contaminants and heavy metals. By combining several separation
processes and targeting dierent groups o contaminants, this invention is both
cost eective and has the capability to be used in situ.
Produced water or wastewater rom coal-methane acilities and other industries
contains a complex mixture o contaminants, such as colloidal particles, molecular-
weight organic contaminants, heavy metal ions, and soluble electrolytes. Currently
available processes or industrial wastewater treatment have limitations that makethem unattractive to coal-methane operations. Desalination, ion exchange, and
osmosis techniques incur increased energy costs due to high temperature and high
pressure operating conditions; these methods also result in detrimental eects on
the treated water.
The invention combines sorption, electrosorption, magnetic seeding, and
subsequent magnetic ltration to separate contaminants. Magnetically responsive
activated carbon, plus a technique or orming this material, is central to the process.
This method typically includes activated carbon in a solution with ions o errite
orming elements; increasing the pH o the solution then produces particles o errite
that bond to the activated carbon. In addition, the invention provides a means o
ltering wastewater using magnetically activated carbon.
Advantages • Lower energy consumption
• Reversible operation
• Minimal secondary waste
• Eective separation at low concentrations o
target species
• Controlled adsorbent mobility
Potential Applications

Advanced Credentialing for
Trusted Networks
Technology SummaryDuring and ollowing disasters, rapid, valid systems are needed to exchange
inormation—among emergency responders, with others in the community,
and with the outside world. ORNL researchers have developed a Web 2.0
credentialing system that oers greater assurance o the validity o inormation
on social networks and media and the potential to thus improve and enhance
the unimpeded ow o vetted inormation and resources during and ollowing a
disaster to assist impacted areas and populations in restoration and recovery.
Traditional communication media are oten overwhelmed during disasters.
O equal concern, recent disasters have demonstrated that people are turning
more to social media as opposed to traditional communication media or their
inormation. Government use o social media can save time and money, provide
greater transparency, provide easier access to inormation and services, and
ensure essential inormation reaches all citizens. However, use o social media orcommunication raises serious issues o security, authenticity, trust, and privacy.
Credentialing programs to overcome some o these concerns exist, but they
tend to be hardware- or sotware-based and use time-consuming and expensive
methods to identiy and certiy individuals and groups. ORNL’s credentialing
system and services are hardware agnostic; use all existing credentials; and require
no new or additional equipment, networks, materials, or inrastructure.
Based on proven credentialing systems such as those used in the travel industry,
the ORNL system includes our main components: (1) a recruitment program
using social media websites to enlist (validate) individuals and enterprises beore
disasters; (2) a managed portal with a set o services to permit users and enterprises
to register profles, build networks, and establish levels o trustworthiness
based on both sel-signed and externally authenticated recommendations and
certifcations rom public and private sources; (3) a quick response code generationacility to allow users and enterprises to create, print, and scan barcodes that link
back to their trust network profles; and (4) an Internet accessible application that
links member profles to mobile applications.
Advantages
• Hardware agnostic
• Uses existing technology
• Leverages existing credentials
• Doesn’t require investment in new or
additional equipment or inrastructure
• Flexible; allows on-the-y changes
• Accommodates a broad array o participants,
both public and private
• Provides immediate and ubiquitous
access control
• Complies with Department o Homeland
Security National Incident Management
Systems requirements • Low cost
Potential Applications
• Credentialing and authenticating personnel

activities, and events
• Credentialing and authenticating personnel

Technology SummaryInternet searching can produce some pleasantly
serendipitous results, but more oten the results are
rustrating because o the avalanche o inormation.
ORNL researchers are making the process less painul
and more ruitul with a tool that produces ranked,
user-oriented search results.
Text-based searches merely retrieve document lists
based on user input words. Studies have shown that
ranking search results based on user preerences can
vastly improve user/searcher satisaction. Numerous
attempts to develop personalized searches/search
engines have been attempted. However, getting theinormation to do this reliably is time consuming, can
be intrusive to the user, and is not always accurate because o the difculty users have explicitly describing what they want/value and
the difculty o keeping such interest “lists” up-to-date. Also, most o the algorithms developed to produce more tailored results stop
at the document level, rather than word level, leading to less specicity. And with the number o documents available this can not only
lead to document overload (the current situation), but also to less accuracy (i.e., retrieval o less relevant inormation and/or missed
inormation).
ORNL took a unique approach based on user dwell times: the time a user spends looking at individual search results. Because existing
browsers and systems don’t provide dwell time inormation, the researchers developed a browser plugin which is able to record the
time a user spends reading a certain webpage/document and automatically send that data to a server or analysis. Ater the user’s
attention times on a collection o documents have been acquired, an ORNL-developed algorithm predicts the user’s attention time on
a new document, down to concept word level, through document content similarity analysis. This inormation is then used to rank the
results o new searches, based on likely interest. In tests, results rom the ORNL ranking algorithm were rated higher than those rom
popular web search engines and other ranking algorithms.
