Improved cycling stability of high nickel cathode material for lithium ion battery through Al- and Ti-based dual modification

A high nickel cathode material, NCAT15, co-doped with Al and Ti and coated with α-LiAlO 2 and Li 2 TiO 3 , was prepared. NCAT15 could significantly suppress the occurrence of interfacial side reactions and effectively improve the cyclic performance.
