Multifunctional Phosphorus Doping: Integrating Enhanced Ionic/Electronic Transport and Interface Optimization for Silicon Oxycarbide Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Phosphorus doping introduced additional electrons into silicon oxycarbide (SiOC) materials, facilitating fast ion/electron transport. It also induced the formation of more stable and Li‐ion conductive interfaces, contributing to the improvement of electrochemical performance.

Ag‐Induced Phase and Defect Engineering of Co‐Evaporated Sb2Se3 Thin Films for Enhanced Photovoltaic Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The sequential formation of Ag2Se and AgSbSe2 phases at the Sb2Se3/Mo interface upon Ag incorporation in co‐evaporated Sb2Se3 solar cells promotes grain growth and defect passivation. These newly formed intermediate phases enhance crystallinity and suppress recombination, leading to significant improvements in open‐circuit voltage, fill factor, and ...

Organotrifluoroborate‐Driven Phase Stabilization and Defect Suppression for Wide‐Bandgap Perovskites

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional additive, trifluoro(pyrrolidin‐1‐ium‐1‐ylmethyl) borate (PyMe‐BF3), leverages B‐F coordination and N‐H hydrogen bonding to passivate undercoordinated Pb2+, fill halide vacancies, and suppress phase segregation. Its preferential enrichment at the buried interface targets the defect‐rich region, enabling simultaneous wide‐bandgap ...

Molten Salt Electrolyte for Enhanced Low‐Temperature Sodium Liquid Metal Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces the application of a low‐temperature, high‐conductivity, solvent‐free Na/KFSI molten salt electrolyte in sodium liquid metal batteries. Additionally, this electrolyte facilitates the formation of a stable and NaF‐rich cathode electrolyte interphase (CEI) on the alloy cathode, enabling stable cycling at an unprecedentedly low ...

Enhancing Anode‐Free Lithium Metal Batteries: A Lightweight MPTS‐MXene Current Collector for Superior Performance and Energy Density

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces an MPTS‐modified MXene current collector for anode‐free lithium metal batteries (AFLMBs). A key advantage of MPTS‐MXene is its ultralight weight, only 15% as heavy as standard copper per unit volume. Its special layered structure and Si‐O rich surface help lithium deposit smoothly and flat, while forming a protective layer that ...

In Situ Bilayer Interphase Enables Air‐Stable Li Metal Anode for Long‐Term Li‐Air Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An in situ formed bilayer SEI—featuring an Ag/LiF‐enriched inner backbone and a CF3‐dominated hydrophobic outer shell—enables fast/uniform Li+ transport and exceptional moisture‐air stability for Li metal. Lithium metal is an attractive anode for next‐generation high‐energy batteries, but its practical use is plagued by dendrite growth and parasitic ...
