Abstract: A nonaqueous electrolyte secondary battery includes a positive electrode of vanadium pentoxide, a negative electrode of lithium-doped carbonaceous material, and an organic electrolyte liquid containing a lithium salt. The electric capacities of the positive and negative materials are selected such that the electric capacity of the carbonaceous material at a potential of 1 volt or lower vs. lithium counter electrode is 0.8 to 1.8 times the electric capacity of vanadium pentoxide at a potential of 2.5 volts or higher vs. lithium counter electrode. Graphitized mesophase microspheres resulting from carbonization of pitch is preferred carbonaceous material. The battery is improved in both charge/discharge cycle and overdischarge properties.

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.
