Portable electronics and electronic devices are rapidly developing and energy storage devices with good electrochemical performances are thus highly needed. The battery market worth 958.4 million USD by 2022 according to the new market research report by MarketsandMarkets?.?The advanced energy storage technologies with low-cost and high-safety warrant are required.?
Besides the widely used lithium ion batteries, zinc-based batteries represents another one of the promising solutions to electrochemical energy-storage technologies with a high-capacity zinc metal anode and high ionconductivity electrolyte. The zinc metal electrode offers a low redox potential and shows dramatic stability in water resulting in a potentially large voltage window of zinc ion batteries (> 2V). However, the zinc-based batteries, is the widely used alkaline electrolytes, like commercialized non-rechargeable?Zn/MnO2 technology. The alkaline electrolytes are not environmentally friendly and lead to poor rechargeability of the batteries due to the formation of irreversible discharged species, such as ZnO, Zn(OH)2. It is highly urgent to develop a high-voltage, environmentally friendly (mild electrolyte needed) zinc battery with long cycling stability.
