Microscale Tin–Bismuth Alloy Prepared via Cooling Rate Control as Anode Material for High‐Performance Lithium‐Ion Batteries

Advanced Functional Materials, Volume 36, Issue 4, 12 January 2026.
To investigate the mechanisms about the enhanced buffering effect and morphological retention in fully lithiated Sn–Bi alloys, this study introduces a new bulk bimetallic Sn–Bi alloy with fine grains of uniformly distributed Sn and Bi alloys (≈50 nm) via cooling rate control. This design effectively relieves internal energy buildup and suppresses crack

Molten Salt Electrolyte Enables Micro‐Sized Silicon Anode in Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 1, January 2026.
Introducing a non‐flammable Li0.3K0.35Cs0.35FSA molten salt electrolyte in high‐capacity micro‐sized silicon (mSi) anode, which forms a robust inorganic SEI (LiF, Li3N, Li2O, Li2S), reduces interfacial resistance and accommodates volume changes. The Li||mSi cell achieves 60.7% capacity retention (100 cycles, 99.5% CE), addressing safety and stability ...

Design of Multilayer Cathodes with Graded Porosity and Their Impact on Lithium‐Ion Battery Performance

Energy Technology, Volume 14, Issue 1, January 2026.
This study explores multilayer cathodes with gradient porosity and their impact on electrochemical performance. For direct comparison with conventional single‐layer electrodes, thickness, mass loading, and overall porosity were kept constant. Graded‐porosity electrodes reduce tortuosity, enhance rate capability, and improve cycling stability ...

Enhancing Cycling Stability of All‐Solid‐State Batteries With 3D‐Architectured Interfaces via Controlled Yield Stress and Internal Stress Relaxation

Small Structures, Volume 7, Issue 1, January 2026.
3D interfacial architectures are introduced into all‐solid‐state batteries (ASSBs) to enhance cycling stability under low‐pressure conditions. The 3D interfaces relax internal stress and suppress resistance accumulation during long‐term operation. Integrated structural and electrochemical analyses reveal that 3D interfaces provide continuous contact ...
