On the other hand, we are also curious about whether water could pose some positive impact on the electrochemical properties of phosphate glasses as anode materials in LIBs. After a careful literature survey, we found some reports on the role of water incorporation in enhancing both the electrochemical properties and the ionic conductivity of oxide materials . Specifically, the structural water can increase proton conductivity in phosphate glasses since the weaker O-H bonding contributes to the higher mobility of proton carriers . Moreover, the structural water can enhance the kinetics of energy storage in transition metal oxides by converting the battery-like behavior into ideally pseudocapacitive behavior . These results have broad implications for understanding the relationship between the structure and property for a variety of hydrous oxide systems.
