The latest research progress of cathode materials for aqueous ammonium ion batteries
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 Zn2+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.
