PURPOSE:To provide a full solid lithium secondary battery attaining high voltage, a large capacity, and a high energy density, having excellent charge/ discharge cycle characteristics and excellent safety and reliability, and capable of being miniaturized and made thin. CONSTITUTION:Amorphous V2O5-P2O5 is used for a positive electrode active material in a full solid lithium secondary battery constituted of a positive electrode, a polymer solid electrolyte, and a negative electrode. High voltage, a large capacity, and a high energy density can be attained, excellent charge/ discharge cycle characteristics and excellent safety and reliability are provided, the battery can be miniaturized and made thin, and the characteristics of the full solid lithium secondary battery can be improved. |
