High‐Voltage Stability of LiCoO2 Cathode Materials Composited With Vanadium‐Based Glass Coatings

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Vanadium‐based glasses show fluidity and good wettability toward other materials at low temperatures. The controlled precipitation of nanocrystals in vanadium‐based glasses enhances the material's mechanical properties and electrical conductivity. The VPFL coatings bond to the LiCoO2 interface via chemical bonds.
