Uniaxial compressive strength prediction and ratio parameter optimization of titanium tailings composite backfill materials using intelligent hybrid models

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling

Sustainable Revival of Spent Lithium Iron Phosphate Cathodes in Li‐Ion Batteries: Recycling and Surface Engineering Approaches

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Schematic illustration of the lifecycle of LiFePO4 cathodes. Lithiation and delithiation reactions happen through its discharging and charging processes. Recycling pathways including hydrometallurgy, pyrometallurgy, and direct regeneration enable sustainable reuse of spent LFP materials. Surface modification approaches (carbon, polymer, and metal/metal
