Development of High‐Voltage Aqueous Electrochemical Energy Storage Devices

摘要

>High voltage aqueous electrochemical energy storage devices have gained significant attention recently due to their high safety, low cost, and environmental friendliness. Through the addition of a solid‐electrolyte interphase, usage of a concentrated electrolyte or adjustment of the pH of their electrolytes, it is hopeful to endow these aqueous energy‐storage devices with a broadened voltage. Among all of them, aqueous lithium‐ion batteries have a longer lifespan and a promising future in energy storage systems. Herein, aqueous batteries will be introduced by demonstrating their voltage improvement approaches and progress is focused.
