摘要： PURPOSE:To increase the performance and the life of a battery by using polyaniline with specific peaks in a discharge capacity-voltage distribution curve in the discharge voltage range of 3.8-2.5V vs lithium electrode in a positive electrode mainly comprising polyaniline. CONSTITUTION:A positive electrode mainly comprising polyaniline is used in a battery. The polyaniline used has two peaks in a discharge capacity-voltage distribution curve in the discharge voltage range of 3.8-2.5V vs lithium electrode. The principal peak P1 exists around 3.0V and the subpeak P2 around 3.6V, and the height of the P2 is 0.25 or more of that of the peak P1. Since the polyaniline has the subpeak and the ratio of high voltage component is quite large, discharge voltage drop on high voltage side is slow and discharge capacity is remarkably increased. Polyaniline is synthesized in a reaction medium containing a protic acid by chemical oxidation-polymerization of aniline or acid soluble salt of aniline.
