Batteries, especially lithium-ion technologies, have been an integral part of the advances in portable electronic devices, such as cell phones and lap-top computers. Lithium-ion cells provide compact, safe, high energy density power for many small electronic devices.

With ever-increasing demands for high capacity and/or high energy density, particularly for electric vehicles (EV) and energy storage systems (ESS), various materials, such as high Ni NCM, Li-excess layered cathode, and Li-S, are drawing attention as a future battery material. We are focusing on aforementioned materials to meet those requirements with mechanistic studies.
