An aqueous battery is an electric battery that uses a water-based solution as an electrolyte. The aqueous batteries are known since 1860s, do not have the energy density and cycle life required by the grid storage and electric vehicles, but are considered safe, reliable and inexpensive in comparison with the lithium-ion ones.
Overall, the development of aqueous batteries has been driven by the commercial success of Li-ion organic electrolyte systems in the battery industry.
We also highlight the three key factors that need the most improvement in these aqueous battery systems: higher operating voltage for the cathode, a more stable metal anode interface, and a larger electrochemical stability window of the electrolyte. Aqueous batteries are emerging as a promising alternative to lithium-ion batteries.
Aqueous batteries offer enormous promise in both large-scale fixed power storage and small-scale electronic systems. The usage of aqueous electrolytes does indeed have a number of benefits, such as the eradication of a need for costly and sometimes dangerous organic electrolytes.
Aqueous batteries are emerging power sources due to the merits of high safety, low cost, environmental friendliness, etc. However, several key issues such as narrow electrochemical stability window, dissolution of active materials, notorious dendrite growth and poor cycling lifespan hinder the practical application of aqueous batteries.
However, there is still no representative system for aqueous batteries, such as the lithium battery systems for non-aqueous batteries. Figure 1c displays the varying characteristics of five items, namely voltage, capacity, rate, lifetime, and safety, as these characteristics differ from system to system.
