Abstract: Provided are a regeneration solution of a spent secondary battery cathode material, the regeneration solution including p-type redox molecules, a solvent, and a lithium salt, in which the p-type redox molecules have a reduction potential that is higher than or equal to 1.55 volt (V) and lower than or equal to 3.7 V with respect to a reduction potential (vs Li/Li+) of lithium, a method of regenerating a cathode material and a regenerated cathode material using this, and a method of recycling the regeneration solution.
