Abstract
A new approach for efficient current collection is provided for a nonaqueous electrolyte secondary cell comprising a positive electrode having a polyaniline or conductive organic polymer as an active material, a negative electrode, a nonaqueous electrolyte, and an outer casing having these components received therein. The positive electrode is affixed to the inner surface of an outer casing segment associated with the positive electrode through a conductive adhesive layer having carbon powder dispersed in a base polymer. The cell can recover from an over-discharged state.
