Considering above thermodynamic and structural analysis, the significantly enhanced reversible capacity and rate capabilities of hydrated TVP anode, especially 65RH, could be attributed to its unique and favorable reconstructed architecture by the incorporated water. As is known, the primary way for water incorporation into the network of phosphate glass is formation of P-OH groups, similar to alkali-metal oxide modifiers, resulting in depolymerization of structural network . The structural -OH species in 45RH, 65RH and 85RH samples are stable and maintain a sufficient interlayer spacing to allow the diffusion of Li + ions over multiple cycles . This is the main reason for the improved electrochemical performances. Furthermore, the nanocrystals, which form through hydration, can greatly shorten the Li + ions diffusion paths and the reconstructed surfaces of the nanocrystals provide more active sites for lithium storage. The remaining glass matrix can efficiently accommodate the large volume changes during cycles. Thus, the humidity treatment is a powerful strategy to modify the network structure of the glass and thereby to promote the Li + ions diffusion and to create more active sites for lithiation/delithiation.
