CHARACTERISTICS OF DEEPLY LI-DOPED POLYACENIC SEMICONDUCTOR MATERIAL AND FABRICATION OF A LI SECONDARY BATTERY

摘要

Electrochemical properties of deeply Li-doped polyacenic semiconductor (PAS) material have been investigated. It has been found that a PAS electrode can be doped up to the C2Li stage without any Li-metal electrolysis and that it has a reversible capacity of 850 mAh/g. Fabrication of the secondary PAS battery of the cylindrical type has also been attempted. The energy density of this battery has turned out to be 450 Wh/1, which is about twice as large as that of conventional Li-ion batteries. [References: 17]
