High-performance, nanostructure LiMnPO4/C composites synthesized via one-step solid state reaction
Autor: Tongfu Wu, Liu Panxing, Yan-Feng Chen, Tang Yuefeng, Liang Ni, Jugong Zheng, Cancan Qin, Lu Yanwen
Publikováno v: Journal of Power Sources. 282:444-451
LiMnPO 4 is proposed as more promising cathode material as LiFePO 4 , while poor electronic conductivity and Jahn-Teller effects during charge/discharge processes hinder the electrochemical performance. To overcome these problems, one-step solid stat
