How a Swedish Factory Is Making Batteries from Wood
Episode 128 of The Manufacturing Podcast explores how Swedish startup Ligna Energy is manufacturing carbon-based supercapacitors from lignin, a waste product from paper mills. Lucas and Luna discuss the chemistry behind lignin batteries, the factory process in Örnsköldsvik, and why these wood-based energy storage devices could complement lithium-ion batteries in renewable energy grids, electric vehicles, and industrial sensors. The episode also touches on the broader trend of industrial bioeconomy and the economics of turning forestry waste into high-value components.
