NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

A non-aqueous electrolytic secondary cell provided with positive electrodes (1), negative electrodes (2) and a non-aqueous electrolytic solution, wherein a lithium-containing composite nickel oxide is used as a chief component of the electrode material of the positive electrodes, a lithium-containing titinium oxide is used as a chief component of the electrode material of the negative electrodes, the solvent of the non-aqueous electrolytic solution contains a cyclic carbonic ester and a chain carbonic ester, the cyclic ester and the chain carbonic ester being contained in amounts of at least 10 % by volume of the whole solvent, respectively, and the total content of the cyclic carbonic ester and the chain carbonic ester being at least 60 % by volume of the whole solvent.
