University of Maryland engineers are currently working on a battery made of wood, an innovative, low-cost, environmentally friendly idea. The research team used tiny wood fibers from yellow pine trees to make test batteries — and we mean seriously tiny, the tree fibers are a thousand times thinner than a piece of paper. They use sodium rather than lithium, so the team imagines this battery working best in a large-scale environment, like for storing solar energy at a power plant.
