POSITIVE ELECTRODE ACTIVE MATERIAL AND NON-AQUEOUS ELECTROLYTE SECONDARY CELL |
摘要 |
A non-aqueous electrolyte secondary cell is provided having superior high temperature-operation properties and excellent large current-discharge properties. The non-aqueous electrolyte secondary cell has a positive electrode composed of a positive electrode collector and positive electrode active material layers formed thereon. A positive electrode active material contained in the above layer is formed of a first composite oxide and a second composite oxide mixed therewith. The first composite oxide is formed of grains of a first lithium transition metal composite oxide containing at least nickel as a transition metal and a cover layer formed on at least part of the surface of each of the grains for suppressing decomposition of an electrolyte caused by the first lithium transition metal composite oxide. The second composite oxide is composed of grains of a second lithium transition metal composite oxide. |
