Geochemistry‐Driven Recovery of Li and Fe From Spent LiFePO4 Cathodes via Stabilized Phosphorus Mineralization

EcoEnergy, EarlyView.
A geochemistry‐guided, acid‐free recycling paradigm for spent LFP batteries. ABSTRACT The rapid expansion of lithium iron phosphate (LFP) batteries presents a critical challenge for sustainable end‐of‐life management, where conventional recycling methods heavily depend on intensive acid/oxidant use and overlook persistent phosphorus pollution.

Cobalt‐Free Single‐Crystal Cathodes for Next‐Generation Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cobalt‐free single‐crystal cathodes enhance lithium‐ion battery stability by mitigating fracture, degradation, and phase transitions. This review highlights Ni‐rich layered, Li‐Mn‐rich, spinel, and olivine frameworks, synthesis strategies enabling morphology and defect control, and structural tuning via doping and coatings, offering pathways toward ...

Mineralogical Characterization of Baptistina Asteroid Family: Implications for K/T Impactor Source

, 2011
Bottke et al. (2007) linked the catastrophic formation of Baptistina Asteroid Family (BAF) to the K/T impact event. This linkage was based on dynamical and compositional evidence, which suggested the impactor had a composition similar to CM2 carbonaceous

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

Grain growth and dust settling in a brown dwarf disk: Gemini/T-ReCS observations of CFHT-BD-Tau 4 [PDF]

, 2004
We present accurate mid-infrared observations of the disk around the young, bona-fide brown dwarf CFHT-BD-Tau 4. We report GEMINI/T-ReCS measurements in the 7.9, 10.4 and 12.3 micron filters, from which we infer the presence of a prominent, broad ...

The Significance of Multiple Saturation Points in the Context of Polybaric Near-fractional Melting [PDF]

, 2004
Experimental petrologists have successfully located basaltic liquid compositions parental to mid-ocean ridge basalt that are, within experimental resolution, multiply saturated with three-phase harzburgite or four-phase lherzolite assemblages on their ...
