Battery is any device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy. 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.

This report looks at the patenting activity around batteries, different types of batteries and a different industry involved from various perspectives and highlights the key companies involved. Patents were categorized as per different battery types, industries where these types are used and highlights the various trends for top companies, countries and battery types.

  • 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 (singleuse or "disposable") that are used once and discarded or secondary (rechargeable batteries) that are discharged and recharged multiple times 1600 Gilbert (GB) Establishment electrochemistry study 1791 Galvani (IT) Discovery of ‘animal electricity’ 1800 Volta (IT) Invention of the voltaic cell First electric battery capable of mass production 1802 Cruickshank (GB) • 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 Electricity through magnetism 1833 Faraday (GB) Announcement of Faraday’s Law 1836 Daniell (GB) • Batteries are made from many materials including various metals, carbon, polymers and even air. The most common are leadacid 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 1820 Ampère (FR) Invention of the Daniell cell 1859 Planté (FR) Invention of the lead acid battery 1868 Leclanché (FR) Invention of the Leclanché cell 1888 Gassner (US) Completion of the dry cell 1899 Jungner (SE) Invention of the nickel-cadmium battery 1901 Edison (US) Invention of the nickel-iron battery 1932 Shlecht & Ackermann (DE) 1947 Neumann (FR) Invention of the sintered pole plate Successfully sealing the nickel-cadmium battery Mid 1960 Union Carbide (US) Development of primary alkaline battery Development of valve regulated lead acid Mid 1970 battery Commercialization nickel-metal hydride 1990 battery 1992 Kordesch (CA) Commercialization reusable alkaline battery 1999 Commercialization lithium-ion polymer 2001 Anticipated volume production of proton exchange membrane fuel cell
  • 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 Search Search Queries Results Searched online sources to come up with related classes CPC:("H02J7/00" or H01M* or "A01K31/17" or "A43B7/04" or "B22D25/04" or "B60K1/04" or "B60K6/28" or "B60R16/033" or "B60R16/04" or "B60R25/40" or "B60S5/06" or "B60W10/26" or "B62M6/90" or "B65D85/88" or "C10B5/18" or "F21L4/00" or "F21L4/08" or "F21S9/02" or "F23Q7/16" or "F41A25/00" or "F41G3/04" or "G01R31/36" or G05F or "H01G9/00" or "H02H7/18" or 1.
