Abstract
Lithium metal oxides may be regenerated under ambient conditions from materials recovered from partially or fully depleted lithium-ion batteries. Recovered lithium and metal materials may be reduced to nanoparticles and recombined to produce regenerated lithium metal oxides. The regenerated lithium metal oxides may be used to produce rechargeable lithium ion batteries.
Claims20
A method for producing lithium metal oxides, the method comprising:
- forming a mixture of at least one lithium halide and at least one metal oxide;
- reducing the lithium halide and the metal oxide to respective nanoparticles of lithium and nanoparticles of metal;
- and
- combining the nanoparticles of lithium with the nanoparticles of metal in the presence of oxygen to produce regenerated lithium metal oxide.
