COMPLETELY SOLID SECONDARY CELL

摘要

PROBLEM TO BE SOLVED: To solve a problem that an useless volume portion which does not contribute to charging-discharging is generated in the interior of an apparatus, an electricity amount corresponding to a data process amount cannot be fed and a production cost is high relatively to the electricity amount fed. SOLUTION: A completely solid secondary cell intervenes a solid electrolyte between a pair of positive and negative electrodes and mounts a collector outside of the electrodes, and the electrodes have a content of an active material of at least 97% and is formed of a sintered body having a density of at least 60%.
