Scientists make ‘green’ battery using wood

The scientists discovered that after charging and discharging the sodium-ion battery hundreds of times, the was was wrinkled but still intact.

Scientists from the University of Maryland have made a “green” battery using a sliver of wood covered with tin. While this sounds like a perfect do-it-yourself project, it isn’t; the parts in the battery tested by scientists are a thousand times thinner than a piece of paper.

Instead of using lithium, which is found in many rechargeable batteries, the scientists utilized sodium to fulfill their goal of making an environmentally friendly battery. Unlike lithium batteries, sodium doesn’t keep energy as efficiently. Instead, this battery is ideal for keeping massive amounts of energy at once just like solar energy at a power plant.
