SECONDARY BATTERY

摘要

PURPOSE:To reduce self discharge and lengthen discharge life by using a conductive polymer and electrolyte which have a specified constitution. CONSTITUTION:A conductive polymer is polyaniline whose molar ratio of hydrogen to carbon is 0.75-0.85 and having an anion structure in its principal chain. Electrolyte is prepared by dissolving a double salt of lithium in a mixture solvent of propylene carbonate and ether. Anions are doped by charge and undoped by discharge. This means that anions are released from polyaniline. Thereby, self discharge of a battery is reduced and discharge life is lengthened.
