Researchers from Sweden's Royal Institute of Technology and California's Stanford University are working on creating wooden batteries made with a special lightweight and porous aerogel-type material. This material resembles the kind of foam you'd see in a mattress although it's harder.
The material was then treated with electrically conductive ink, allowing it to maintain an electrical charge. Its three-dimensional shape allows it store more power in less space than a regular battery, which uses two-dimensional coils.
These squishy wooden batteries could have a wide range of applications. They could be used in pretty much any and every kind of flexible electronics as well as smart fabrics and electric cars. Ultimately, they would enable more efficient and convenient use of electronic devices.
