结论新型4 V材料ε-VOPO 4具有良好的电化学性能。在第一次还原过程后,材料转变为α-LiVOPO 4相,其中Li离子以松散结合的五配位键结合,
ConclusionsThe appealing electrochemical properties of the new 4 V material, ε-VOPO4, appear to arise from a combination of sources. After the first reduction process, the material is transformed to the α-LiVOPO4 phase where the Li ions in loosely bound five-coordi-
