Stacking-Dependent Interfacial Water Dynamics Govern the Aqueous Degradation of Layered LiCoO2 Cathodes.

Key Points

• The aim is to determine how interfacial water dynamics affect the degradation of layered LiCoO2 cathodes in aqueous environments.
• Identified dissolution barriers associated with interfacial water dynamics.
• Examined the relationship between stacking and aqueous durability of cathodes.
• Interfacial water acts as a kinetic gate for dissolution.
• Layered LiCoO2 cathodes show variation in degradation rates based on stacking configurations.
