Abstract
A non-aqueous secondary cell having a compound of manganese oxide, lithium salt and metal oxide as an active material of a positive electrode is disclosed. A negative electrode comprises lithium or lithium alloy. The above positive electrode improves the charge/discharge cycle characteristic and charge/discharge reversibility of the cell and can be produced at a low cost.
