Innovative battery chemistry revolutionizes zinc-air battery

Science Daily  January 4, 2021
An international team of researchers (Germany, China, USA – University of Maryland, US Army Research Laboratory) has developed a zinc-air battery based on an innovative, non-alkaline, aqueous electrolyte bringing a previously unknown reversible zinc peroxide chemistry into the zinc-air battery. The new battery overcomes the high chemical instability, parasitic reactions in the usage of alkaline electrolytes lead to electrochemical irreversibility. The electrolyte which is based on the zinc trifluoromethanesulfonate salt, has several decisive advantages – the zinc anode is used more efficiently with a higher chemical stability and electrochemical reversibility, operate stably for 320 cycles and 1,600 hours under ambient air atmosphere, and the increased energy density has now the potential to compete with the lithium-ion battery. The zinc-air battery provides a potential alternative battery technology with environmental friendliness, high safety, and low costs…read more. TECHNICAL ARTICLE
