SECONDARY CELL

摘要

A secondary cell wherein a positive pole using an Li-containing composite metal oxide as the active material and a negative pole using a carbonaceous material as the active material are isolated by a separator in a jar containing organic electrolyte, and a moisture content in the organic electrolyte is from 5 to 450 ppm. This secondary cell has excellent current efficiency, cycle characteristics, preservation characteristics and stability, and can be used advantageously for various electric and electronic appliances. Particularly, it can drive portable electronic appliances including IC devices operating at 3.5 to 2.6 V.
