Swedish Research Project Proposes Electric Car Batteries… Made of Wood?

by Gage Taylor

These days, it seems rare that a week passes where we don’t hear about some new kind of exotic or outlandish approach to electric car construction. With technology moving at a breakneck pace and interest in the field at an all-time high, concerns over range, power delivery, and cost are to be expected. But where most announcements seem to revolve around nanotechnology or other synthetic materials, a team of researchers from the KTH Royal Institute of Technology in Sweden announced this week that they’d constructed a small-scale model of an electric vehicle battery pack made from wood. By developing a new carbon-fiber material which has lignin, a natural polymer found in nearly every dry-land plant on earth, as its main ingredient, they’ve made a big step toward cheaper, more energy-dense batteries.
