摘要

Constructing uniform nanoceramic coating layers is a well-known challenge in the field of coating materials. Herein, Al _(2) O _(3) -coated Li[Li _(0.13) Ni _(0.305) Mn _(0.565) ]O _(2) (LLNM) Li-rich cathode materials are successfully prepared through a dry prilling coating (DPC) method. The structures and electrochemical performances of the Al _(2) O _(3) -coated products are systematically examined. Typically, the cycling stability is enhanced and voltage degradation upon cycling is reduced, benefiting from the unique and controllable nano-sized Al _(2) O _(3) coating layer. Moreover, metal ion dissolution is avoided when using the DPC method, which is eco-friendly and suitable for large scale production.
