Battery: Basics and History of Development

• An battery is any device consisting of one

or more electrochemical cells that convert

stored chemical energy into electrical

energy. Batteries are either primary (single-

use or "disposable") that are used once

and discarded or secondary (rechargeable

batteries) that are discharged and

recharged multiple times

• Batteries are made from many materials

including various metals, carbon, polymers

and even air. The most common are lead-

acid batteries used in vehicles and lithium

ion batteries used for portable electronics.

Batteries come in many shapes and sizes,

from miniature cells used to power hearing

aids and wristwatches to battery banks the

size of rooms that provide standby power

for telephone exchanges and computer

data centers

• Batteries have recently received significant

research and development, because they

are hoped to provide a solution for energy

storage in a transition from fossil fuels to

alternative energy, both for transport and

electricity production and for powering

portable devices of all kinds

Search Strategy and Sequence of steps

Using PatSeer as our database a sequence of steps was used to create our search query. Since, in PatSeer records are not grouped by

families by default we searched individual records and later collapsed them by one member per Family or collapsed results by Patents

and Applications.

The table below shows sequence of steps we followed. We started with a combination of relevant CPC & IPC Classes to restrict the

result set to relevant records. The publications included in the report are updated as of 9th October, 2013

• Reference to number of records relates to Unique Records (collapsing patents and applications from

result set) or Unique Families (collapsing by Extended Families)

• For this landscape report, companies were categorized into different industry types and different

battery types were also identified

• It should be noted that since by convention patents are usually classified and published within

eighteen months after filing, the patent record set covering 1976- present may not be complete.
