Design Strategies for Electrolytes in Lithium Metal Batteries: Insights into Liquid and Solid‐State Systems

Batteries &Supercaps, EarlyView.
This review systematically analyzes electrolyte design strategies for lithium metal batteries, covering both liquid and solid‐state systems in parallel. Liquid strategies such as high‐concentration, fluorinated, and additive‐engineered electrolytes are discussed, as well as polymer‐, ceramic‐, and composite‐based solid electrolytes, highlighting their ...

Keggin‐Type Aluminum Polyoxometalate‐Mediated Oxidation of Amorphous Carbon for Engineered Electrochemical Interfaces

Carbon Energy, EarlyView.
Keggin‐type Al‐POM‐coated silica achieves selective surface oxidation of amorphous carbon through electrostatic attraction and proton‐coupled oxidation, tailoring interfacial properties for lithium‐ion batteries and semiconductor processes. ABSTRACT Amorphous carbon is widely used in energy storage and semiconductor technologies, where surface ...

Alloying Cu, Fe, and Co in Ni/YSZ Electrodes for High‐Temperature CO2 Electrolysis: Impact on TPB Density, Activity, and Carbon Deposition Resistance

Carbon Energy, EarlyView.
Systematic alloying of Ni with Cu, Fe, and Co in Ni/YSZ electrodes modifies active site density up to 43%, decreases activation energies by up to 44%, and reduces carbon deposition fourfold. Cu–Ni alloy is among the most promising alloy catalysts for electrochemical CO2 reduction in SOECs.

Synergistic Fe–Si Dual‐Site Pathway Engineering in Biomass‐Derived Carbon Matrix for High‐Performance Oxygen Reduction Reaction

Carbon Energy, EarlyView.
We report a dual‐atomic Si–Fe–N–C catalyst synthesized from nitrogen‐rich pinecones and an Fe porphyrin precursor. The inherent Si and N in pinecones form a porous Si–N–C framework that stabilizes Fe atoms during pyrolysis, yielding robust Si–Fe dual sites.
