Abstract
The high rate discharge performance and cyclability are improved. A battery having a hich capacity density and excellent cyclability and safety performance can be produced. A composite active material provided with a polymer on the surface of a carbon-based active material in an amount of from 0.01% to 5% by weight is used. Further, a composite active material provided with a polymer on the surface of a carbon-based active material in an amount of from 0.04 to 4% by weight is used. In particular, the former composite active material is used as a positive active material while the latter composite active material is used as a negative active material to obtain a non-aqueous electrolyte battery.
