A systematic review of efficient recycling for the cathode materials of spent lithium-ion batteries: process intensification technologies beyond traditional methods

Abstract

With the successive retirement of lithium-ion batteries (LIBs) approaching, there has been an upsurge of spent LIBs, posing significant challenges to energy, resources, and environment, which has led to the...

Strategy for Efficient Recovery of NCM Materials by the Reagent-Free Method: Green Recovery of Lithium and High-Value Byproducts through Capacitive Deionization Reverse Applications

“…Conventional hydrometallurgical recovery for inorganic acid leaching metal ion involves a lengthy process, huge and costly chemical consumption, little selectivity, leached metal contaminants, and easily corroded equipment. , Organic acid leaching has little equipment corrosion and no secondary pollution, but it has drawbacks such as long reaction times, high temperatures, and slow reaction kinetics. In the context of carbon peaking and carbon neutrality, it is urgent to reduce carbon emissions, and it is particularly important to explore low-cost organic acid leaching or acid-free leaching technologies. − …”

Recycling spent lithium-ion battery cathode: an overview

“…The recycling and utilization of S-LIBs are a hot topic, which has attracted attention from many scholars. Recently, many scholars such as Men et al , 23 Lei et al , 60 Wang et al 61 and Jia et al 47 published excellent reviews related to the recycling of S-LIBs. However, compared to these excellent reviews, our review has unique features.…”
