Non-aqueous electrolyte secondary battery with a lithium copper titanium oxide electrode
Provided is a non-aqueous electrolyte secondary battery capable of ensuring good characteristics even in case of low-voltage charge at 2.5 V or so. A composite oxide of a compositional formula, LiaCubTicO4 (with 0<a&lE;1, 0<b&lE;0.5, 1.5&lE;c<2) serving as a positive or negative electrode active material is mixed with an electroconductive agent and a binder, and shaped under pressure into electrodes for the battery.
