A recycling process for Lithium-ion (Li-ion) batteries employs a closely monitored co-precipitation reaction for precipitating cathode active material precursor (pCAM) in a comingled form of metal salts corresponding to the intended chemistry for the new battery. The coprecipitation relies on a controlled pH that assures a particle size, morphology and purity of the resulting precipitated pCAM. A combination of internal reactor pH sensing within the coprecipitation reactor along with external pH sensing to validate the sensed pH ensures a consistent target pH throughout the coprecipitation process, compensating for drift or sensor failure in view of the harsh reactor environment.
