Engineering Stress‐Decoupled SnP2O7@Carbon Core Shell via Spatial Confinement for Cycling‐Stable Sodium Storage

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Tin‐based composite oxides typically undergo severe volume variations and exhibit poor intrinsic conductivities despite their high theoretical capacity as promising anode candidates for sodium‐ion batteries. This results in rapid structural degradation and capacity fading upon cycling.

Defect Engineering of Carbon Frameworks Driven All‐Slope Hard Carbon Anodes for Fast‐Charging Sodium‐Ion Batteries

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Fast‐charging capability is one of the crucial factors determining the application prospects of sodium‐ion batteries (SIBs). Nevertheless, the mismatched sodium storage kinetics and Coulombic efficiency (CE) in hard carbon anodes are bottlenecks in the implementation of fast‐charging SIBs. Herein, we propose a facile pre‐carbonization strategy

Multifunctional Integration in a Monolithic Biomass Carbon: A Triple‐Synergistic Host for Advanced Lithium–Sulfur Batteries

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Lithium–sulfur (Li–S) batteries are promising for next‐generation high‐energy‐storage systems but are hindered by polysulfide shuttle, sluggish kinetics, and volume expansion. Conventional carbon hosts struggle to simultaneously anchor and convert polysulfides efficiently.

Synergizing Multi‐Chemisorption Sites and Micropore Confinement in Porous Carbon for High‐Performance Zinc‐Ion Hybrid Capacitors

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Aqueous zinc‐ion hybrid capacitors (ZICs) bridge the gap between high‐energy batteries and high‐power supercapacitors, yet their performance is fundamentally bottlenecked by the micropore confinement effect in carbon cathodes, which restricts hydrated Zn2+ transport and active site utilization.

Structural Modification and Deformable Design of Electrospun Sn@C Nanofiber Anodes Through Oxide Doping for Flexible Lithium‐Ion Batteries

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Size‐controllable Sn nanoparticles are designed in this work via oxide doping to be uniformly embedded into flexible N‐doped carbon nanofibers, in which the agglomeration and migration of Sn are effectively restrained due to the suppressive effect of selected oxides, including SiO2, TiO2, and ZnO. Benefiting from unique merits of the embedment

MXene‐Based Materials Contribute Better Alkali Metal–Chalcogen Batteries: Progress, Challenges, and Perspectives

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Alkali metal–chalcogen batteries (AMCBs) are one of the most promising next‐generation energy storage systems because of their high energy density and reasonably low cost. However, the practical application of AMCBs is severely hindered by the volume expansion of the chalcogen cathode, the shuttle effect of polychalcogenides, and unstable ...
