Research Progress of M^(+)/Zn^(2+)(M=Li,Na,K)Aqueous Hybrid Ion Batteries

水系电池以安全性好,成本低及环境友好等优点,使其在大规模领域中应用具有极大前景。然而,水系电池不仅要保持以上三个标准,还需保证电化学性能优异。过去几年,关于水系混合离子电池的正极材料以及锌电极等方面的研究已稍有成就。以锌为负极的水系混合离子电池与单一离子电池相比能量密度大,稳定性好。本文对不同种类的水系混合离子电池进行系统地阐述,对电极材料,电解质以及金属锌负极优化等方面进行评价和总结,最后展望水系混合离子电池的发展前景。

The advantages of aqueous batteries,such as good safety,low cost,and environmental friendliness,have a great prospect in large-scale applications.However,aqueous batteries must not only maintain the above three standards but also need to ensure excellent electrochemical performance.In the past few years,there have been some achievements in the research of aqueous hybrid ion batteries cathode materials and zinc electrodes.Among them,the aqueous hybrid ion batteries using zinc as the negative electrode has a higher energy density and better stability than a single ion battery.In this paper,different kinds of aqueous hybrid ion batteries are systematically described.The electrode materials,electrolytes and the negative electrode optimization of metallic zinc are evaluated and summarized.Finally,the development prospects of aqueous hybrid ion batteries in the future are prospected.
