The main object of this research is to optimize the synthesis process and complete patent application based on this technology in two years and eventually transfer the developed technology to domestic industry. This is the second year project. Electrode material manufacturer will be invited to join this project, and technology transfer will be carried out before the end of this project.鋰離子電池正極富鋰鎳錳層狀氧化物粉體合成Li-ion batterycathodeLi-excess layered oxidepowder
