In article number 2001671, Guoying Chen and co‐workers developed a new method to introduce partial fluorine substitution into the oxygen anion sublattice of lithium‐rich cation‐disordered rocksalts. This results in enhanced redox processes of both transition‐metal cations and oxygen anions, enabling more reversible lithium extraction and insertion. Advanced lithium‐ion battery cathode materials with significantly improved performance were obtained.

锂离子电池:一种改善阳离子无序岩盐阴极性能的氟化方法(Adv。Energy Mater。35/2020)

Chen Guoying Chen和他的同事们在编号2001671中开发了一种新方法,将部分氟取代引入富锂阳离子无序岩石盐的氧阴离子亚晶格中。这样可增强过渡金属阳离子和氧阴离子的氧化还原过程,从而使锂的提取和插入更具可逆性。获得了性能得到显着改善的高级锂离子电池正极材料。
