Abstract

This invention provides a cylinder type nonaqueous secondary battery which comprises a positive electrode active material comprising a lithium-containing transition metal oxide, a composite oxide or composite chalcogen negative electrode material capable of intercalating and deintercalating lithium and a nonaqueous electrolyte containing a lithium metal salt, wherein high discharging capacity and excellent charge and discharge cycle characteristics are obtained by mounting a metal foil mainly comprising lithium in advance in a coiled group in which a current collector sheet coated with the positive electrode active material (positive electrode sheet), another current collector sheet coated with the negative electrode material (negative electrode sheet) and a separator are coiled in a spiral form.
