A team of researchers in China has created a method to revive aging lithium-ion battery cells, allowing them to perform almost as if they were new. This ‘injection’ technique could revolutionize the electric vehicle (EV) sector, which faces challenges regarding battery disposal and recycling. A typical lithium-ion battery lasts 8-12 years, leading to high replacement costs. By using machine learning, the team identified lithium trifluor as a candidate molecule to supply fresh lithium ions to depleted cells, potentially easing financial strain and environmental concerns related to battery waste.
The use of machine learning helped the researchers identify a promising new molecule, lithium trifluor, to rejuvenate aging lithium-ion batteries, potentially saving users significant costs.
Gao expressed a vision for battery recovery, comparing it to giving an injection to a sick person: 'If we can give an injection to a sick person to help them recover, why can't we have a magic potion for drained batteries, too?'
Typically, lithium-ion battery packs last eight to twelve years before deemed 'dead', imposing a large financial burden on EV owners when replacements are needed.
The new technique not only prolongs the lifespan of EV batteries, but also addresses environmental concerns related to battery disposal and toxic leaks, making it a significant breakthrough.
