Most batteries are rigid and incompatible with water. But people work and play in oceans and estuaries, and they could benefit from flexible and saltwater-safe power sources.

Researchers have created the prototype design of a new rechargeable battery specifically intended to operate in saltwater environments. This innovation can be utilized as an energy source in ocean or sea regions due to its flexibility and toughness.

Researchers develop a yarn-like battery that operates in seawater, powering LEDs and timers, offering flexible energy solutions for marine applications.
