LiLaPO4-coated Li[Ni0.5Co0.2Mn0.3]O-2 and AlF3-coated Li[Ni0.5Co0.2Mn0.3]O-2 blend composite for lithium ion batteries
A blended composite of LiLaPO4-coated Li[Ni0.5Co0.2Mn0.3]O-2 and AlF3-coated Li[Ni0.5Co0.2Mn0.3]O-2 was tested as the cathode of lithium secondary batteries. The rate capability, cyclic performance, and thermal stability of the blended electrode were characterized and compared with pristine, AlF3-coated, and LiLaPO4-coated electrodes. The blended sample showed good cyclic performance and thermal stability, which implies that blending these two cathode coatings were effective in obtaining their advantages and lessening their weaknesses.
