Fast Lithium Intercalation Mechanism on Surface‐Modified Cathodes for Lithium‐Ion Batteries (Adv. Energy Mater. 44/2023)

Li-Ion Batteries In article number 2302402, Masaaki Hirayama and co-workers clarify the mechanism of fast Li+-intercalation in the Li-ion battery using a Li2ZrO3-modified LiCoO2 cathode with a model film electrode and in-situ neutron reflectometry. The cathode electrolyte interphase on the modified LiCoO2 consists of inner and outer layers. The inner layer facilitates the desolvation of Li+, resulting in fast Li+-intercalation.
