Stabilization Perspective on Metal Anodes for Aqueous Batteries

Huaping Wang et al.

Summary: Aqueous electrolyte-based batteries have advantages such as nonflammability, low cost, high power density, and environmental friendliness, but they suffer from low energy density due to the narrow stable electrochemical window of water and electrode materials with low capacity. Developing metal anodes with high specific capacity is seen as a promising solution to enhance the energy density of these batteries.
