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
