From the above analyses, it can be stated that the incorporated -OH species, which keep stable during cycling, in TVP glass is the decisive factor for the substantially boosted electrochemical performances of the glass anodes (Fig. ). In a recent study, it was found the -OH groups were responsible for the improved cycle life and reversible capacity of electrodeposited films of bilayered vanadium oxide (EC-V2O5) relative to the sol-gel derived V2O5 phases . In addition, it was also found that a moderate amount of lattice water in K0.77MnO2⋅0.23H2O electrode can act as pillars to stabilize the expanded interlayer region required for fast K + ion diffusion, thus leading to high electrochemical performance of K-ion batteries . This implies that the incorporated water, in particular the -OH species, along with the disordered domains and the ordered structures in the hydrated sample synergistically contributed to the boosted capacities.
