水系铵离子电池正极材料最新研究进展

The latest research progress of cathode materials for aqueous ammonium ion batteries

目前二次电池的研发主要集中在金属载体上,近年来,NH_(4)^(+)因其来源丰富、摩尔质量较轻且其水合离子半径远远小于Li^(+)、Na^(+)及Zn^(2+)水合离子半径而引起人们的关注。本文围绕水系铵离子电池正极材料的最新研究进展展开,目前其正极材料的研究主要包括普鲁士蓝类似物、钒基材料、锰基材料,并在此基础上进一步指出了即将面临的机遇和挑战。

At present,the research and development of secondary batteries is mainly concentrated on metal carriers.In recent years,ammonium ion has attracted people’s attention because of its rich source,relatively light molar mass and its hydrated ion radius is much smaller than Li^(+)、Na^(+)and Zn^(2+)hydrated ion radius.In this paper the latest research progress of cathode materials for aqueous ammonium ion is carried out.At present,the research of positive electrode materials mainly includes Prussian blue analogue,vanadium based materials and manganese based materials,and further pointed out the upcoming opportunities and challenges on this basis.
