Gallery: “Brown Liqour” Could Replace Rare Metals in Batteries


For decades, paper mills have long used a thick sticky byproduct of the wood-pulping process—”Brown Liqour”— as a combustible fuel to keep the mills in motion. Now a collaborative research project by scientists at Linköping University in Sweden and Poznan University of Technology in Poland has found a way to transform this “brown liqour” into a battery cathode which could cut out the need for expensive rare metals used in batteries such as cobalt. While we may not be huge fans of cutting down trees, the brown liquor tech could reduce the cost of batteries and has the potential to increase our ability to store and distribute solar and wind power.
