Recycling of spent lithium-ion batteries (LIBs) is essential for both environmental protection and natural resource conservation. Carbothermic reduction active materials has been a research hotspot LIB recycling. However, the high reaction temperature limited solubility Li2CO3 in reduced product seriously restricted its industrial application. Here, based on catalytic effect alkali metal salts carbothermic reduction, novel process that features lower temperature, accurately controlled...
The remarkably increasing consumption of lithium ion batteries (LIBs) has been an issue worldwide for the contained valuable metals and intrinsic toxicity in spent LIBs. Here, a novel process including selective leaching precipitation developed recovery carbothermic reduction LiNixCoyMn1–x–yO2 was applied to control degree target metallic elements. Afterward, H3PO4 solution utilized selectively leach 99.1% Li 96.3% Mn, excellent selectivity achieved that merely 4.5% Co 1.2% Ni were...

The rapid growth in demand for lithium ion batteries (LIBs) results the generation of a vast amount spent LIBs. Recovery valuable metals from LIBs is required terms environmental protection and natural resource conservation. Here, we developed novel process sustainable recovery Li Co LiCoO2 cathodes based on situ reductive roasting. In operation roasting, Al foil cathode performs as an reagent converting into Li2O, CoO, Al2O3. Lithium aluminum roasting products can be selectively leached...
Abstract All‐solid‐state lithium–sulfur batteries (ASSLSBs) are considered promising next‐generation battery technologies due to their high energy density and intrinsic safety. However, the poor electron Li + transport of sulfur‐based cathodes, along with interface resistance, result in insufficient sulfur utilization efficiency subpar rate performance. Herein, a “one‐stone‐three‐birds” design strategy integrated hosts is proposed enhance solid‐state redox reaction species. By fabricating...
Binders are the key components for maintaining integrity of sulfur electrodes in lithium‐sulfur batteries. However, traditional insulating binders have a negative impact on charge transfer within electrodes, which is an important factor leading to poor rate performance Herein, ionic conductive binder (LPABM‐d‐LATP) based interface compatibilization fast conductor was synthesized by in‐situ emulsion polymerization and lithiation neutralization. The modified Li1.3Al0.3Ti1.7(PO4)3 nanoparticles...
Activated carbon with abundant nanoporous structures can effectively adsorb 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) molecules. However, an atomistic understanding of its underlying adsorption mechanism is still urgently needed because TCDD, given strong toxicity, requires strict testing conditions in experiments. In this work, a series grand canonical Monte Carlo (GCMC) simulations were performed to evaluate the effects slit width and pore size distribution (PSD) activated carbons on TCDD...
