EM Railgun project in Navy demands safe, high energy and long cycle life Li-ion batteries. In this Phase I research, we will demonstrate the feasibility of Li2MSiO4 cathode materials for this application. Special thin coatings will be self-assembled on the nanosize particles to significantly improve the performance to achieve high capacity (> 200 mAh/g) at > 4V with extended cycle life. The sol-gel chemistry, process will be developed and a Li-ion cell will be fabricated. The results generated in the Phase I will be used to optimize the process in Phase II.
