Abstract:Orthorhombic LiFePO4 (LFP) offers highly reversible
redox reactions, making it an attractive cathodic material for lithium-ion
batteries. This electrochemical property was exploited to develop
an environmentally benign selective lithium extraction process based
on CO2 and hydrogen peroxide that can be applied to direct
LFP recycling. The proof of concept of this green delithiation process
was demonstrated in a previously published paper, while the process
optimization and the establishment of the reaction kine… Show more
“…While this recycling approach has proven to be very effective for various cathode materials, it has only achieved low lithium recovery rates when applied to LFP. 39 Seeing that understanding of reaction mechanism and kinetics can foster process development of battery recycling, 40,41 in our study we want to delve deeper into this process by investigating different ball-milling parameters to uncover the fundamental reaction mechanisms behind the reductive mechanochemical recycling of LFP. Additionally, the subsequent leaching process and Li recovery stages were analysed to explore potential avenues for making recycling of LFP effective and protable.…”
