NONAQUEOUS SECONDARY CELL

摘要

A cylinder type nonaqueous secondary cell comprising a positive active material such as a lithium-containing transition metal oxide, a negative active material containing a composite oxide or composite chalcogen capable of adsorbing and emitting lithium, and a nonaqueous electrolyte containing a lithium salt, wherein a current collector sheet (positive plate sheet) coated with the positive active meterial, a current collector sheet (negative plate sheet) coated with the negative active material and a separator are wound together into a coil, which includes lithium-base foil to obtain high capacity and good charge/discharge cycle.
