Competing ion effects and electrolyte optimization for electrochemical lithium extraction from spent lithium iron phosphate battery cathodes
Stefanie Arnold, Volker Presser
Abstract
Electrochemical Li + recovery from spent LFP batteries achieves 18 mg g −1 after NaOH pH adjustment of the leaching solution. Competing ions (Na + /K + ) challenge long-term stability, mandating optimized pH and selective electrodes.
