A new recycling process allows for ‘direct reuse’ of precious lithium battery electrodes without energy- and material-intensive treatment.
Researchers at Aalto University in Finland discovered that cobalt-containing electrodes in lithium batteries can be reused ‘as is’ after being newly saturated with lithium. Compared to conventional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new process saves valuable raw materials – and likely also energy.
“In our earlier study of how lithium cobalt oxide batteries age, we noticed that one of the main causes of battery deterioration is the depletion of lithium in the electrode material. The structures can nevertheless remain relati ....
