Kaust Research In Saudi Arabia Creates Simple, Cheap Technique That Increases The Lifespan Of Aqueous Batteries Tenfold For Widespread Use

Researchers at King Abdullah University of Science and Technology (Kaust) in Saudi Arabia have found a way to extend the lifespan of aqueous batteries by more than ten times. The breakthrough could benefit systems used in electric cars, mobile phones, and large-scale energy storage.

In rechargeable batteries, the anode is responsible for generating and storing energy. However, the presence of free water — unbound molecules — causes parasitic reactions that degrade the system and reduce its efficiency over time.

The Role Of Zinc Sulfate

The study, published in Science Advances, points out that adding zinc sulfate stabilizes water molecules, acting as a kind of “glue.”

Universal Application And Feasibility

Although the tests primarily used zinc sulfate, the researchers noted that other sulfate salts also provide similar benefits across different metal anodes.

According to the paper, sulfate salts are cheap, stable, and widely available, making the solution feasible for large-scale application. This paves the way for advancements in the development of more durable and cost-effective batteries.

Impact On Electric Cars

Aqueous batteries are gaining prominence as a sustainable alternative for energy storage. The expectation is that the global market will exceed US$ 10 billion (about R$ 55 billion) by 2030.

Unlike lithium batteries, common in hybrid and electric vehicles, aqueous batteries offer greater safety and potential for integration with renewable sources, such as solar energy, in electrical grids.

Most importantly, the technique proposed by the scientists could accelerate the adoption of these batteries, providing a more sustainable option for the future of mobility and clean energy generation.
