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.

Beyond birds: rethinking bird‐centered pathogen models in light of insect migration
Ecography, EarlyView.Migration redistributes biomass, nutrients, and pathogens across ecosystems. For decades, migratory birds have been treated as the default long‐distance pathogen vectors, shaping both conceptual frameworks and empirical models of disease ecology.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.
