Single-step battery cathode recycling
A new battery recycling method developed by Illinois Grainger engineers removes scarce, expensive metals from old battery cathodes and coats them onto new cathodes in a single step. The result is significantly more affordable, less environmentally impactful and less risky to health than any recycling method currently in use.
Battery cathodes – the positive part of the battery that helps to store electrical energy – often require rare, expensive metals such as cobalt. It is therefore crucial to develop effective means for recycling cathodes that reclaim the metals essential to their operation.
