All the above-mentioned aspects motivated us to conduct a systematic study with respect to the impact of water on the electrochemical performances of the TeO2-V2O5-P2O5 (TVP) glass-based anode for LIBs. We subjected the TVP glass powders to different degree of humidity treatment at constant temperature. The water-reacted glass powders were mixed with additives to fabricate the anodes for LIBs. We characterized the electrochemical properties of the water-reacted TVP glass anodes and evaluated their dependence on humidity. An optimum humidity was found, which caused an enhancement of the Li ion storage capacity by 133%, i.e., from 180 mA h g -1 for the 'dry' glass anode to 420 mA h g -1 for the anode based on the 65% humidity treated glass. The origin of this significant enhancement is thoroughly investigated in this work.
