Lithium ion batteries have been studied as major power resource for decades due to their high energy density, cycling ability and low self-discharge rate. For the next generation of such batteries, intensive research has been done to develop improved electrode materials. The objective of this project was to produce a new kind of cathode material, which would be applied to different industrial areas. The synthesis of Li2MnSiO4 through hydrothermal reaction was examined in terms of optimal reaction conditions. The results indicated that heating the raw materials at 180Â¡Ã¦ for 42h, and then annealing it at 700Â¡Ã¦ for 10h would produce better products. Hydrothermal reaction is a promising method to produce the Li-rich cathode due to high yields, low reaction temperature, and short reaction time.
