- Abstract
- A Li[Li 0.19Ni 0.16Co 0.08Mn 0.57]O 2 cathode was coated with AlF 3 on the surface. The AlF 3-coating enhanced the overall electrochemical characteristics of the electrode while overcoming the typical shortcomings of lithium-enriched cathodes. This improvement was attributed to the transformation of the initial electrode layer to a spinel phase, induced by the Li chemical leaching effect of the AlF 3 coating layer.
