Synthesis and electrochemical performance of Li[Ni0.7Co0.1Mn0.2]O2/C cathode materials

Recently, Lithium ion batteries have been widely investigated due to the demands for high energy density, power and safety in large-scale applications such as PHEV, HEV, EV and energy storage systems. LiCoO2 cathode material has commercialized dominantly thus far, because it has good productivity and cycling performance. Co, however, as one of the starting materials, is expensive and highly toxicity. Furthermore, LiCoO2 shows relatively low thermal stability and discharge capacity, which are essential in new cathode materials for the next generation lithium ion batteries.
