Frontispiece: Atomic Level Fabrication of Oxychloride Interface for High‐Rate and High‐Voltage Lithium‐Ion Batteries

In the Research Article (e17806), Changhong Wang, Xueliang Sun, and co-workers report a self-limiting vapor-phase chemical reaction route to precisely synthesize oxychloride coating at atomic level on cathode materials. The superior lithium ionic conducting nature and outstanding high voltage stability of the deposited oxychloride play a critical role in maintaining cathode structural integrity, while ensuring excellent high-rate and high-voltage performance for lithium-ion batteries.
