| Outline of Final Research Achievements |
Fusion reactors need deuterium and tritium as their fuel. Since tritium does not exist in nature, it is necessary to produce tritium in a reactor by neutron irradiation of lithium (Li).
I have developed an innovative method for recycling Li from used Li-ion batteries using the Li ionic conductor. Only Li ions in a solution of used Li-ion batteries permeate during electrodialysis; the other ions, including Co, Al, and F, do not permeate the Li ionic conductor. Li0.29La0.57TiO3 was selected as the Li ionic conductor, and the applied dialysis voltage was 5 V. The Li recovery ratio increased with electrodialysis time.
After electrodialysis, CO2 gas was bubbled in the Li recovery water to produce lithium carbonate (Li2CO3) as a raw material for Li-ion batteries. This new method for recycling Li-ion batteries shows good energy efficiency and is easily scalable. Thus, this electrodialysis method is suitable for the recovery of Li from used Li-ion batteries.
