Numerous LiFePO4 batteries have been retired with the increasing development of electric vehicles and hybrid electric vehicles; meanwhile, the spent LiFePO4 batteries will lead to an environment contamination and the resources squander if they do not recycled reasonable. In this paper, a green process is developed for the recovery of spent LiFePO4 cathode materials with a certain amount of impurities:...
Poly(3,4-ethylenedioxythiophene)–polystyrenesulfonate and manganese oxide (PEDOT:PSS/MnO2) hybrids were prepared via a facile solvothermal method coupled with an oxidative polymerization route. The effects of the reaction temperature and the KMnO4-to-organic monomer (3,4-ethylenedioxythiophene, EDOT) ratio on the morphology, structure, and electrochemical properties of the materials were investigated...
Lithium difluoro(oxalate)borate (LiODFB) is acknowledged as a new type of electrolyte lithium salt with great potential for high-voltage lithium-ion batteries. Utilizing Raman spectroscopy, a conductivity tester, and a viscometer, this study concentrates on the solution structures and properties of LiODFB-solvent systems. The results demonstrated that in the sulfolane (SL) solvent, the main coordination...
