摘要
过渡金属氧化物(TMOs)作为锂离子电池(LIBs)的转化型负极材料,因其具有高容量、低成本等优点,具有较大的应用潜力。然而,TMOs材料的电压滞后问题限制了其能量效率,阻碍了TMOs材料的实际应用,给该领域的研究人员提出了严峻的挑战。文章讨论了电压滞后问题的形成机理及其改善方法,展望了TMOs材料的发展前景和研究趋势。
As conversion anode materials for lithium-ion batteries(LIBs),the transition metal oxides(TMOs)have great application potential because of the advantages of high capacity and low cost.However,the voltage hysteresis of TMOs limits the energy efficiency and hinders the practical application,posing a severe challenge to researchers.In this paper,the formation mechanism of voltage hysteresis and its improvement method were discussed;a future perspective of the research direction for TMOs materials were outlined.
