A method of obtaining metal ions from a battery, the method comprising adding a crushed battery to a leaching solution comprising fruit and an ammonium salt, thereby obtaining a leachate comprising metal ions.
A method of obtaining a metal salt from a battery, the method comprising:
- (a) adding a crushed battery to a leaching solution comprising fruit and an ammonium salt, thereby obtaining a leachate comprising metal ions;
- and
- (b) adding a precipitating agent to the leachate to obtain a precipitate comprising the metal salt.
A method of recovering and regenerating a lithium cathode material from a lithium-ion battery (LIB), the method comprising:
- (a) adding a crushed LIB to a leaching solution comprising fruit and an ammonium salt, thereby obtaining a leachate comprising metal ions;
- (b) adding a precipitating agent to the leachate of step (a), thereby obtaining a precipitate comprising metal salt;
- and
- (c) mixing the precipitate of step (b) with a lithium salt and heating the resulting mixture to obtain a lithium cathode material.
