镁电池研究进展

Study of magnesium battery

镁电池具有比能量高(2 202 m Ah/g),电极电位为负(-2.36 V),较锂电池价格便宜,且放电平稳、无毒,结构简单,是21世纪的理想新能源,在综述了镁一次电池、镁二次电池、镁空气电池和双电解液镁电池的工作原理、特点及其应用现状的基础上,讨论了镁电池的发展方向。

High specific energy （2 202 mAh/g）, negative standard Electrode potential, cheaper pdce than lithium battery, smoothly and non-toxic discharge, and simple structure were the characteristics of magnesium battery. It was a very promising anode material for primary high energy density batteries in the 21st century. Based on summarizing the working principle, the characteristics, and application status of Mg/MnO2 battery, rechargeable magnesium battery, magnesium-air battery and double liquid electrolyte of Mg batteries, the development direction of magnesium batteries were discussed.
