Recent progress in rechargeable alkali metal-air batteries

Green Energy & Environment 2016年第1期1卷 4-17页

作者： Xin Zhang Xin-Gai Wang Zhaojun Xie Zhen Zhou Tianjin Key Laboratory of metal and Molecule Based Material Chemistry Institute of New Energy Material ChemistryCollaborative Innovation Center of Chemical Science and Engineering(Tianjin)School of Materials Science and EngineeringNational Institute for Advanced MaterialsNankai University

Rechargeable alkali metal-air batteries are considered as the most promising candidate for the power source of electric vehicles(EVs) due to their high energy density. However, the practical application of metal-air batteries is still challenging. In the past decade, many strategies have been purposed and explored, which promoted the development of metal-air batteries. The reaction mechanisms have been gradually clarified and catalysts have been rationally designed for air cathodes. In this review, we summarize the recent development of alkali metal-air batteries from four parts: metal anodes, electrolytes, air cathodes and reactant gases, wherein we highlight the important achievement in this filed. Finally problems and prospective are discussed towards the future development of alkali metal-air batteries.

关键词： metal-air batteries alkali metal anodes Electrolytes Ionic liquids Air cathodes
