Smart, ecofriendly new battery to solve problems
Present-day lithium batteries are efficient but involve a range of resource and environmental problems. Using materials from alfalfa (lucerne seed), pine resin and a clever recycling strategy, Uppsala researchers have now come up with a highly interesting alternative.
‘We think our discovery can open several doors to more environment-friendly, energy-efficient solutions for the batteries of the future,’ says Daniel Brandell, Senior Lecturer at the Department of Chemistry, Uppsala University, one of the researchers behind the idea.
In their latest study, researchers at Uppsala University’s Ångström Laboratory have developed a whole new battery concept. The battery is based on recovery and renewable biological material with an energy content corresponding to that of current lithium-ion batteries. Components of the battery are made of renewable organic biomaterials from alfalfa and pine resin, and can be recycled with a low energy input and non-hazardous chemicals, such as ethanol and water.
Daniel Brandell adds: ‘The use of organic materials from renewable sources makes it possible to solve several of the problems that would arise from a huge rise in the use of lithium batteries.
