PURPOSE:To increase voltage and stabilize operation by using a plurality of unit cells connected in series whose positive electrode is an insoluble-infusible substrate containing a polyacetone skeletal structure, and whose negative electrode is lithium. CONSTITUTION:The cell is constituted of a positive electrode 1, a negative electrode 2, a current collectors 3, 3', and electrolytic solution 4, a separator 5, a cell case 6 and an external terminals 7, 7'. A plurality of unit cells whose positive electrode 1 is an insoluble-infusible substrate containing polyacetone skeletal structure whose value of specific surface area according to BET method is 600m<2>/g or more, whose negative electrode 2 is lithium, whose aprotic organic solvent of a compound which can produce an ion capable of doping a positive electrode active material by electrolysis is the electrolytic solution 4 are connected in series. If a voltage abnormality of overdischarging or overcharging, etc., occurs, therefore, a behavior to relieve the abnormality is indicated so that no large deterioration due to cycles can be recognized. It is thereby possible to realize high voltage and stabilize operation. |
