摘要: 以LiVO3、V2O5、V2O3为原料,在600℃、氮气氛中经32h固相反应合成的β LixV2O5(0.3 ≤ x ≤ 0.6),在200~400℃电池电化学反应过程中,其β-钒青铜型结构不变。这说明β LixV2O5是一种结构稳定的二次电池固溶体电极材料。Abstract: βLixV2O5 (0.3 ≤ x ≤ 0.6) shall be synthesized through solidoid reaction of raw material,LiVO3,V2O5,V2O3 in Nitrogen atomsphere of 600℃ for 32 hours.The performance of βLixV2O5(0.3 ≤ x ≤ 0.6) in electrochemical reaction of battery shows that βLixV2O5 main-tains its β-vanadium bronze structure,subject to the temperature ranging from 200℃ to 400℃,therefor βLixV2O5 is a kind of solid solution electrode material with solid atructure in rechargeable battery.
