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.
基于摇椅式的锂离子电池（LIBs）已广泛应用于消费电子产品和电动汽车（EVs），以解决当前全球范围内的化石燃料枯竭和环境污染问题。然而，由于电动汽车和电网规模储能站商业化对锂离子电池的需求前所未有的增长，以及锂和钴的短缺，成本的增加促使人们开发低成本的可充电电池系统。双离子电池（DIBs）中阳离子和阴离子都参与电化学氧化还原反应，由于其工作电压高、安全性好且与传统的基于摇椅式的锂离子电池相比具有环境友好性，是满足商业应用低成本要求的最有前途的候选者之一。然而，双离子电池技术仅处于基础研究阶段，需要付出相当大的努力来进一步提高能量密度和循环寿命。我们回顾了其发展历史和现状，并讨论了双离子电池涉及的反应动力学，包括阴极的各种阴离子嵌入机制，以及阳极的反应，包括嵌入和合金化，以探索实现低成本高性能双离子电池的有前景的策略。
