The Korean Institute of Machinery and Materials (KIMM) has developed a battery that opens up some interesting possibilities in energy storage. Researchers developed this battery with high safety and stretchability by mimicking the scales and flexible joints like a snake.
Snake scales can fold into the next to protect them against external attacks or collisions. KIMM researchers used this concept for designing a battery that can stretch without compromising stability and performance.
So to achieve this, researchers used small, hexagonal-shaped lithium-ion battery cells that look like snake scales. Then they electrically connected these battery cells with polymer and copper materials.
While testing, the stretchable lithium battery was found to perform well even when bent out of shape and subjected to a stretching ratio of 90 percent, across more than 36,000 cycles.
These serpentine-inspired batteries could see applications in the world of robotics, wearable electronics, or other applications where flexibility is required.
This innovation could also prove to be helpful in medical devices that are used to help sick people or in the rehabilitation of older people. The new robotic device could also prove as a lifesaver during disaster scenarios. Consider sending a snake-like robot during an earthquake-like situation. It can easily make its way through the boulders and broken glass to confirm the location of a trapped victim. This could help in saving many lives.
