Title: Inorganic nonaqueous electrolyte battery
Inventor: YOSHIMITSU KAZUMI
IPC: H01M4/96
Filed: 1987-12-01
Abstract: PURPOSE:To increase discharge capacity by substituting aromatic hydrocarbon for a part of carbon which is positive electrode material and using the aromatic hydrocarbon together with carbon as the main components of the positive electrode. CONSTITUTION:A positive electrode 1 is formed with a positive electrode material mainly comprising aromatic hydrocarbon and carbon. The reaction of thionyl chloride is conducted on the surface of the carbon in the positive electrode 1. By substituting aromatic hydrocarbon which forms benzen skeleton on the surface of a carbon particle for a part of carbon particle, the aromatic hydrocarbon dissolves in an electrolyte 4, and the dissolved aromatic hydrocarbon forms no primary and secondary particle unlike carbon. The surface area is therefore remarkably increased, and discharge capacity is increased compared with the use of only carbon. Since the positive material can be reduced, the amount of lithium or thionyl chloride is increased and discharge capacity is increased.
