LiLaPO{sub 4}-coated Li[Ni{sub 0.5}Co{sub 0.2}Mn{sub 0.3}]O{sub 2} and AlF{sub 3}-coated Li[Ni{sub 0.5}Co{sub 0.2}Mn{sub 0.3}]O{sub 2} blend composite for lithium ion batteries

A blended composite of LiLaPO{sub 4}-coated Li[Ni{sub 0.5}Co{sub 0.2}Mn{sub 0.3}]O{sub 2} and AlF{sub 3}-coated Li[Ni{sub 0.5}Co{sub 0.2}Mn{sub 0.3}]O{sub 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, AlF{sub 3}-coated, and LiLaPO{sub 4}-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.
