Abstract
A non-aqueous electrolyte secondary battery has a negative electrode, a positive electrode and a non-aqueous electrolyte with lithium ion conductivity. A composite oxide containing lithium represented by composition formula Li.sub.x Si.sub.1-y M.sub.y O.sub.z (where M is one or more kinds of elements selected from metals other than alkaline metals, and metalloids other than silicon, and x, y and z satisfy O.ltoreq.x, 0<y<1, and 0<z<2) is used as an active material for the negative electrode. The battery exhibits a negative active material with a lower and baser potential and a large charging/discharging capacity to produce a long cycle service life secondary battery which facilitates a large current charging and discharging and reduces deterioration due to excess charging and excess discharging.
