WHOLE SOLID SECONDARY BATTERY

摘要

PURPOSE:To obtain a whole solid secondary battery having excellent high-rate characteristic by including fibrous graphite and spherical graphite as the electron conductive material in an electrode made of the mixture of silver ion conductive solid electrolyte and a specified electrode active material. CONSTITUTION:Two kinds of fibrous graphite and spherical graphite having excellent electron conductivity are included in an electrode made of the mixture of silver ion conductive solid electrolyte shown with 4AgI.Ag2WO4 or the like and electrode active material made of the compound oxide which consists of silver shown with AgxV2O5-y(0.6<=x<=0.8, y means oxygen loss) and vanadium oxide. Especially, in the case that a total inclusion rate of the described two graphite in the electrode is at 1-2weight%, high-rate characteristic can be improved remarkably.
