Environmental and Resource-Saving Aspects of Zinc-Ion Batteries for Sustainable Energy Storage
摘要
The article discusses the problems that arise during the operation of lithium-ion batteries (LIB). In this regard, in recent years much attention has been paid to finding solutions to replace LIBs with cheaper and safer alternatives. This article discusses the advantages and disadvantages of zinc-ion batteries (ZIBs) as energy storage devices for mobile phones, laptops, e-bikes, cordless power tools, electric cars and electric buses. The article provides a process flow chart for the production of zinc using a hydrometallurgical method. Modern equipment and technical solutions in the production of zinc allow us to reduce the harmful impact on the environment and ensure its high quality. This increases the economic attractiveness of zinc-ion batteries. Among ZIBs, the most promising is Aqueous Zinc ion battery (AZIB). Aqueous ZIBs are a viable, environmentally friendly and cost-effective energy storage technology. This article discusses the problems that currently prevent the transition from lithium-ion to aqueous zinc-ion batteries. The problems that arise during the design of AZIB are related to the growth of dendrites and corrosion of the zinc anode, as well as the release of hydrogen. Solving these problems will allow AZIB to enter the stationary energy market, reduce the harmful impact of lithium production technologies on the environment, eliminate the problem of its disposal, the danger to human health and fire hazard, and reduce the cost of energy storage.
