Abstract:
A cathode active material of a lithium ion battery includes a number of LiNi0.5Mn1.5O4 particles and an AlF3 layer coated on a surface of the LiNi0.5Mn1.5O4 particles. A method for making the cathode active material is provided. In the method, a number of LiNi0.5Mn1.5O4 particles are provided. The LiNi0.5Mn1.5O4 particles are added to a trivalent aluminum source solution to form a solid-liquid mixture. A fluorine source solution is put into the solid-liquid mixture to react and form an AlF3 layer coated on the surface of the LiNi0.5Mn1.5O4 particles. The coated LiNi0.5Mn1.5O4 particles are heat treated to form the cathode active material. A lithium ion battery including the cathode active material is also provided.
