Abstract: Since the commercialization of lithium-ion batteries (LIBs) in 1990, they evolved to improve energy density. To achieve this purpose, it is need to increase the available capacity of cathode, optimize manufacturing process of electrode material and increase the voltage limit. When estimating the performance improvement of LIB for xEV by 2020, the battery capacity will increase by more than 120 Ah, 1.4 times and the weight energy density will be doubled to 320 Wh kg-1. For these reasons, it is necessary to develop a silicon-carbon composite anode material, a cathode material having a nickel content of more than 80% and a multifunctional and high performance electrolyte.
