Abstract:
Disclosed is a C2/m-structured cathode material for a lithium-ion battery. The cathode material includes a lithium transition metal oxide represented by a formula of: Li(LiwNixCoyMnz)O2, wherein w+x+y+z=1, 0.42≦z≦0.60, 0.30≦x+y≦0.55, any of w, x, and y is larger than 0, and the cathode material having a single-phase structure with a space group of C2/m. A lithium-ion battery containing the C2/m-structured cathode material is also disclosed.
