Abstract
A nonaqueous secondary battery is disclosed, comprising a positive electrode sheet containing a lithium-containing transition metal oxide as a positive electrode active material, a negative electrode sheet having at least one layer containing a negative electrode material capable of intercalating and deintercalating lithium, and a nonaqueous electrolyte containing a lithium metal salt, wherein the battery into which an electrolytic solution has been injected is sealed, subjected to charging treatment having at least two stages, and subjected to storage treatment having at least two steps. A process for preparing such the nonaqueous secondary battery is also disclosed.
