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 […]
