Lithium nickel cobalt aluminum oxide (NCA) cathode material, CAS number 193214-24-3, is considered one of the most promising of the next generation cathode materials that provides higher capacity than LiCoO2, especially for HEV and PHEV due to its high energy density, high thermal stability, and low toxicity.

It has been well known that carbon nanotubes, other metal or metal oxides modified lithium cathode materials can help to improve the battery capacity and durability. With a relatively larger ion radius, titanium ions could modify the oxygen lattice and change the local coordination environment of the layered lithium nickel cobalt aluminum oxide, resulting in decreased cation migration, better kinetic and thermodynamic properties, and improved structural stability. Ti-substituted NCA cathode exhibits impressive reversible capacity (198 mA h g-1 at 0.1 C) with considerable cycle stability under a cut-off voltage up to 4.7 V.
