| abstract |
A positive electrode containing a transition metal and / or a transition metal compound (eg, Cu and / or Cu compound), a non-aqueous electrolyte, and a negative electrode containing a material that occludes and releases lithium, wherein the LiCl is a positive electrode In a non-aqueous electrolyte, a non-aqueous electrolyte, and a non-aqueous electrolyte secondary battery contained in at least one of the negative electrode, a metal component of the current collector is prevented from being dissolved in the non-aqueous electrolyte due to a charge / discharge reaction, and charge / discharge is possible. I do. The present invention is characterized in that a current collector substantially made of Ni or a Ni alloy is used as a current collector of a positive electrode. [Selection diagram] None |
