摘要:

近年来,钠离子电池的研究受到了越来越多的关注,过渡金属氧化物因易制备、低成本、高容量和高电化学活性等优点,被认为是最有潜力实现产业化的钠离子电池正极材料。NaFe1/3Ni1/3Mn1/3O2作为三元过渡金属氧化物钠离子电池正极材料,在已有的一元材料、二元材料的基础上,进一步提高了正极材料的电化学性能。以三元金属氧化物NaFe1/3Ni1/3Mn1/3O2为模型,研究了导电纳米材料改性对其电化学性能的影响,提供了提升三元过渡金属氧化物钠离子电池正极材料性能的掺杂策略。

Abstract:

In recent years, the research of sodium?ion batteries has received more and more attention, and transition metal oxides are considered to be the most potential cathode material system for industrialization due to their easy preparation, low cost, high capacity and high electrochemical activity. As the cathode material of ternary transition metal oxide sodium?ion battery, NaFe1/3Ni1/3Mn1/3O2 further improves the electrochemical performance of cathode materials on the basis of existing monic materials and binary materials. In this paper, the influence of conductive nanomaterial modification on its electrochemical performance was studied using ternary metal oxide NaFe1/3Ni1/3Mn1/3O2 as a model, and a doping strategy was provided to improve the cathode material performance of ternary transition metal oxide sodium?ion batteries.

Key words: Sodium?ion battery, Cathode materials, Transition metal oxides, Ternary materials, Graphene
