PROBLEM TO BE SOLVED: To provide a solid polyelectrolytic battery wherein a discharge characteristic is improved. SOLUTION: Electrolyte supporting salt consisting of fluorine compound of lithium(Li) is contained in a solid polyelectrolyte 6, and ionization potential Ip/eV by the highest occupied molecular orbital method of the electrolyte supporting salt is made to be not less than 6 and not more than 9. The discharge characteristic can be improved by limiting the ionization potential Ip/eV by the highest occupied molecular orbital method of the electrolyte supporting salt within the range. In other words, by limiting the range of the ionization potential Ip/eV, elemental composition of the electrolyte supporting salt is not changed and a decomposition reaction and the amount of decomposition products of the electrolyte supporting salt are suppressed, thereby the discharge characteristic is made to be improved. |
