Abstract
The present invention provides a proton migration type secondary battery using as an electrode active material a polymer having a quinoxaline structure exhibiting a large proton insertion-release capacity, the secondary battery being excellent in its safety, reliability and rapid current properties, and having a long life and a high weight energy density (kWh/kg), compared with the conventional aqueous solution type double layer capacitor and a lead acid battery using sulfuric acid.Also, the present invention provides a proton migration type secondary battery excellent in productivity and further in safety and reliability by using a solid electrolyte and/or a gel electrolyte obtained by curing a mixture of a polymerizable compound excellent in its polymerizability and a proton conductive electrolyte.Further, the present inventors provide a proton migration type secondary battery having a further long life and excellent in reliability by adding a non-electrically conductive powder to the electrolyte.
