Enhancing the long-cycling performance of a LiNi0.8Co0.15Al0.05O2@LaNiO3 cathode material by surface modification

Herein, the introduction of hexagonal LaNiO 3 on the surface of LiNi 0.8 Co 0.15 Al 0.05 O 2 provides a protective and adaptable ultrathin layer to stabilize the microstructure of Ni-rich layered cathode materials, enhancing the electrochemical and thermal stability.
