Advancing Upcycling and Regeneration of Spent LiFePO4: Failure Mechanisms and Recovery Strategies

Carbon Energy, EarlyView.
This review studies the failure mechanism to promote the upcycling regeneration of spent lithium iron phosphate (S‐LFP). It first summarizes the failure mechanisms of LFP batteries revealed via advanced characterization technologies and then explores the respective advantages and challenges of hydrometallurgy and direct regeneration methods.

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction

Universal and Normalized Regeneration of Heterogeneous Spent LiFePO4 via Mechanochemical Delithiation and Flash Relithiation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We propose a universal “x → 0 → 1” regeneration route: mechanochemical delithiation converts spent LixFePO4 of any degradation level to FePO4, erasing batch variance; 35‐s flash relithiation yields uniform LiFePO4 with near‐identical capacity, suppressing grain growth and cutting energy andtime by >90% versus furnace sintering, overcoming unpredictable
