New water-powered tech could power batteries that can last hundreds of years without degrading — and are so safe…
- Chinese scientists developed a water battery capable of surviving 120,000 charging cycles reliably
- Neutral electrolytes prevented corrosion that usually destroys aqueous batteries over time
- The battery reportedly lasts centuries under normal grid storage operating conditions
Scientists from the City University of Hong Kong and Southern University of Science and Technology have developed a new type of water-based battery that could last for hundreds of years without losing its capacity over time.
Published in Nature Communications, the device uses synthesized covalent organic polymers as an anode for magnesium and calcium ions instead of traditional battery materials.
The researchers found a specific compound that combines high-density carbonyl with a rigid honeycomb-like structure that resists corrosion, and this design allows the battery to withstand up to 120,000 charge cycles, which is more than ten times longer than conventional lithium-ion grid storage batteries.
Water batteries are not easy to perfect
Aqueous batteries have...
