Direct regeneration mechanisms of spent lithium iron phosphate cathode materials for sustainable lithium ion battery recycling

Abstract The rapid adoption of lithium iron phosphate (LiFePO 4 , LFP) batteries in electric vehicles has accelerated end-of-life battery accumulation. Conventional pyrometallurgical and hydrometallurgical routes decompose the cathode structure. High energy consumption, significa...

Evaluation and application of iron-modified clay adsorbents for clean fuel production in the frame of desulfurization technology

Abstract This study investigated clay adsorbents for benzothiophene sulfone (BTO) removal through oxidative desulfurization. Bentonite-Fe 3+ (BF3), Fe 6+ (BF6), activated clay-Fe 3+ (ACF3), and Fe 6+ (ACF6) were synthesized via impregnation of raw bentonite (BR) and raw activated...
