CELL COMPRISING POLYANILINE POSITIVE ELECTRODE AND METHOD FOR PRODUCING POLYANILINE POWDER THEREFOR

摘要

A cell comprising a negative electrode made of metal lithium or a lithium alloy, a positive electrode which comprises polyaniline and has a main peak around 3.0 V versus a lithium electrode and a sub-peak around 3.6 V versus a lithium electrode with a height ratio of the sub-peak to the main peak being not smaller than 0.25 in a discharge capacity distribution curve in the discharge voltage range between 3.8 V and 2.5 V versus a lithium electrode, and a non-aqueous organic electrolytic solution containing a lithium salt dissolved therein, which has long discharge life, high energy density, good charge-discharge cycle characteristics and improve load characteristics.
