Vanadium (V)-based glasses have recently garnered considerable attention as promising anode materials for lithium-ion batteries (LIBs) due to their abundance of Li+ storage sites, neglectable volume expansion upon lithiation/delithiation, and ease of preparation. However, the inherently low electrical conductivity and relatively low energy density of V-based glass anodes hinder its application in full LIBs. In this work, we tackled this challenge by optimizing the chemical composition of the V-based glass anode to achieve high-performance half and full batteries. We investigated the impact of partially substituting B2O3 for P2O5 in 50V2O5-(50-x)P2O5-xB2O3 (mol%) (VPB) glass series on its structure and electrochemical performances. The glass with 30mol% B2O3 (VPB30 glass) was found to deliver the highest electronic conductivity, an enhanced reversible capacity of 470mAh g−1 at 1Ag−1 after 500 cycles, and excellent rate capability. The optimized performances were ascribed to the boosted lithium-ion diffusivity and the increased lithium storage sites. We assembled a full cell by coupling a VPB30 glass anode with a LiCoO2 cathode to test its cycling performance. The VPB30//LiCoO2 cell exhibits the required power density, and hence, high practicality. Our work implied the practical application of glass anodes in high-performance LIBs.
