High voltage cathode material for Li-ion batteries |
| 摘要 |
A cathode electrode material for use in rechargeable Li-ion batteries, based on the integration of two Li-based materials of NASICON- and Spinel-type structures, is described in the present invention. The structure and composition of the cathode can be described by a core material and a surface coating surrounding the core material, wherein the core of the cathode particle is of the formula LiMn2-xNixO4−δ (0.5≦x≦0 & 0≦δ≦1) and having a spinel crystal structure, the surface coating is of the formula Li1+xMxTi2-x(PO4)3 (M: is a trivalent cation, 0.5≧x≧0) having a NASICON-type crystal structure. |
