An ecoefficient, economical and sustainable valorization process for the synthesis of Co3O4from waste lithium-ion battery (LIB) by leaching-solvent extract-scrubbing-precipitation stripping route has been developed. Through an optimization, the waste LIB cathode was leached using 2000 mole/m3of H2SO4and 5 Vol. % of the H2O2at a pulp density of 100 kg/m3under leaching time 60 minutes and temperature...
