The synthesis of Li(CoMnNi)O2 cathode material from spent-Li ion batteries and the proof of its functionality in aqueous lithium and sodium electrolytic solutions
Li(CoMnNi)O2 cathode material was recycled from spent Li-ion batteries. Better sodium than lithium cycling stability was evidenced in an aqueous solution. A high Na-storage capacity of 93 mA h g−1 was achieved at a scan rate of 0.8 C. Differences between lithium and sodium charge storage capability were discussed.
