An electrochemical method was developed for efficient recovery of lithium. • In-depth chemical reaction mechanism was explored for recovery of lithium. • A method without extreme low acid condition (pH less than 1.0) and extra oxidant addition. • Optimal leaching efficiencies of lithium and iron ions were 95.53 % and less than 0.01 %. •
Lithium iron phosphate (LiFePO 4) with an olivine structure was first used as a lithium ion battery cathode material in 1997 [1,2,3,4,5]. It has a different structure and a different operating mechanism to the layered cathode material family (LCO = LiCoO 2, NCA = LiNi 0.8 Co 0.15 Al 0.05 O 2 and NMC = LiNi 1−x−y Mn x Co y O 2 ).
Multi-layer lithium iron phosphate (LFP) battery electrodes are exposed to nanosecond pulsed laser radiation of wavelength 1064 nm.Test parameters are chosen to achieve characteristic interaction types ranging from partial incision of the active coating layers only to complete penetration of the electrodes with high visual cut quality.
A LiFePO4 battery, short for lithium iron phosphate battery, is a type of rechargeable battery that offers exceptional performance and reliability. It is composed of a cathode material made of lithium iron phosphate, an anode material composed of carbon, and an electrolyte that facilitates the movement of lithium ions between the cathode and …

This study proposes a green process for selective and rapid extraction of lithium from the cathode materials of spent lithium iron phosphate (LiFePO 4) batteries via mechanochemical solid-phase oxidation. The advantages of the designed process are: (1) acid/base free; (2) extremely short time (5.0 min); (3) wastewater-free discharge; (4) three …
When the O/A ratio was varied using 70% Na-Cyanex 272, the extraction efficiency of Co increased sharply with increasing O/A phase ratio, while for lithium, the extraction efficiency was not so much increased (Fig. 12). The percentage extraction of Co was increased from 29.5% (1:2 = O:A) to 99.8% (2:1 = O:A) with co-extraction of 15% Li.
