Unraveling Synergistic Regulation Mechanism in Nitrogen/Sulfur Co‐Doped Biomass‐Derived Hard Carbon Toward Durable Sodium‐Ion Battery Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nitrogen/sulfur co‐doping optimizes the electron and spatial structure of biomass‐derived hard carbon, and the anode demonstrates superior long‐term cycling stability over 2000 cycles, validating an improved “adsorption‐intercalation‐pore filling” mechanism.

Dual‐Armor Architecture‐Mediated Microstructural Engineering of Germanium Anode for Advanced Liquid‐ and Solid‐State Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐armor structured p‐Ge/SiO2/NC‐2 composite is designed to tackle the large volume variation and interfacial instability of Ge anodes. It combines internal SiO2 support with an outer N‐doped carbon layer to achieve exceptional structural integrity, a robust SEI and continuous conductive networks.

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 ...

Key advantages of high performance lubricants for the manufacturing of powder metallurgy parts

, 2014
In powder metallurgy, the usage of an admixed lubricant to aid the compaction and to ease the ejection of the green parts is most of the time unavoidable.

Alloying variants – A special feature of powder metallurgy

In contrast to classical ingot metallurgy, in which case a chemically homogeneous liquid phase is the initial state, in powder metallurgy solid powders are the starting materials.
