Abstract:
Provided is a new 5 V class spinel exhibiting an operating potential of 4.5 V or more (5 V class), which can suppress the amount of gas generation during high temperature cycles. Suggested is a manganese spinel-type lithium transition metal oxide represented by formula: Li[NiyMn2-(a+b)-y-zLiaTibMz]O4 (wherein 0≦z≦0.3, 0.3≦y 0, b>0, and 3≦b/a≦8.
