Zn2+-Intercalated V2O5·nH2O derived from V2CTx MXene for hyper-stable zinc-ion storage

The intercalated Zn 2+ and abundant interfaces between the conductive V 2 CT x and Zn x V 2 O 5 · n H 2 O can weaken the electrostatic interactions and maintain a large lattice channel during cycling, thus reducing the activation energy of charge transfer.
