Abstract
In a non-aqueous electrolyte secondary battery provided with a positive electrode 1, a negative electrode 2, and a non-aqueous electrolyte solution, a lithium-containing composite nickel oxide is used as a chief component of the positive electrode material for the positive electrode, a lithium-containing titanium oxide is used as a chief component of the negative electrode material for the negative electrode, and the solvent of the non-aqueous electrolyte solution contains a cyclic carbonic ester and a chain carbonic ester in such a manner that the cyclic carbonic ester and chain carbonic ester are contained in amounts of not less than 10% by volume of the whole solvent, respectively, and the total content of the cyclic carbonic ester and the chain carbonic ester is not less than 60% by volume of the whole solvent.
