Improved electrochemical performances of yttrium oxyfluoride-coated Li[Li0.2Mn0.54Ni0.13Co0.13]O2 for lithium ion batteries

The YOF layer has been uniformly coated on the surface of Li[Li0.2Mn0.54Ni0.13Co0.13]O2 cathode materials and moderate amount of YOF-coated Li[Li0.2Mn0.54Ni0.13Co0.13]O2 show improved electrochemical performance. 108
