Effects of impurities on stability of TiC, TaC and ZrC particles in tungsten

Nuclear Materials and Energy
Titanium carbide (TiC), tantalum carbide (TaC) and zirconium carbide (ZrC) in form of particles are widely added in W to improve its mechanical and anti-irradiation properties. However, TiC, TaC and ZrC particles are decomposed to Ti-C-O, Ta-C-O and Zr-C-

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 ...

Interfacial Charge‐Transfer Enhancement via High‐Entropy Alloy Regulated MXene Heterostructures for Asymmetric Supercapacitor Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel core‐shell HEA@MXene composite was synthesized to enhance supercapacitor electrochemistry. DFT simulations reveal the role of HEA doping in regulating the MXene interface. The HEA@MXene composite exhibits a high specific capacitance of 872 F g−1 at 1 A g−1 with remarkable stability in 1 M KOH.

In Situ Constructed TiO2 on Ti3C2‐MXene Cathode Enables Photo‐Assisted Zn‐Ion Hybrid Microsupercapacitors With High‐Energy Density

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A strategy has been developed for the in situ constructed of TiO2 nanoparticles on a Ti3C2‐MXene cathode, which is assembled with a zinc anode to form a photo‐assisted ZIH‐MSC device. The designed light‐assisted ZIH‐MSC device achieved a wide operating voltage (1.3 V) and battery‐level energy density (97 μWh cm−2, 1 mA cm−2), overcoming the limitations
