摇椅型锂离子电池（LIB）已广泛应用于消费电子和电动汽车（EV），以解决目前全球范围内的化石燃料耗尽和环境污染问题。然而，由于电动汽车和电网规模储能站对LIB商业化的前所未有的需求不断增长，以及锂和钴的短缺，不断增加的成本推动了开发低成本可充电电池系统。双离子电池（DIB），其中阳离子和阴离子都参与电化学氧化还原反应，是最有前途的候选人之一，以满足商业应用的低成本要求，因为它们的高工作电压，出色的安全性，和环境友好性相比，传统的摇椅为基础的LIB。然而，DIB技术仅处于基础研究阶段，需要做出相当大的努力来进一步提高能量密度和循环寿命。本文回顾了DIB的发展历史和现状，讨论了DIB的反应动力学，包括阴极的各种阴离子插层机理，以及阳极的反应，包括插层和合金化，以探索低成本、高性能DIB的发展策略。
Rocking‐chair based lithium‐ion batteries (LIBs) have extensively applied to consumer electronics and electric vehicles (EVs) for solving the present worldwide issues of fossil fuel exhaustion and environmental pollution. However, due to the growing unprecedented demand of LIBs for commercialization in EVs and grid‐scale energy storage stations, and a shortage of lithium and cobalt, the increasing cost gives impetus to exploit low‐cost rechargeable battery systems. Dual‐ion batteries (DIBs), in which both cations and anions are involved in the electrochemical redox reaction, are one of the most promising candidates to meet the low‐cost requirements of commercial applications, because of their high working voltage, excellent safety, and environmental friendliness compared to conventional rocking‐chair based LIBs. However, DIB technologies are only at the stage of fundamental research and considerable effort is required to improve the energy density and cycle life further. We review the development history and current situation, and discuss the reaction kinetics involved in DIBs, including various anionic intercalation mechanism of cathodes, and the reactions at the anodes including intercalation and alloying to explore promising strategies towards low‐cost DIBs with high performance.
