High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

Oxygen Vacancy Engineering of Ultrafine ZnAl2O4 Nanoparticles as a Robust Protective Layer for Dendrite‐Free and Long‐Lifespan Aqueous Zn Metal Anodes

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects

Phosphorus‐Doping Drives the Formation of a Pt‐Skin@PtFe Alloy Catalyst With Modulated d‐Band Center for Oxygen Reduction

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...

Atomic Synergy of Vacancy‐Engineered Layered Double Hydroxide/Heteroatom‐Doped Carbon Quantum Dots for Bifunctional Oxygen Electrocatalysis in Zn–Air Batteries

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Low conductivity and poor oxygen reduction reaction (ORR) catalytic activity limit the bifunctional catalytic performance of layered double hydroxide (LDH) in zinc–air batteries. In this work, an efficient bifunctional electrocatalyst was prepared by loading nitrogen and phosphorus co‐doped carbon quantum dots (NPCQDs) onto a cationic‐vacancy ...
