High Entropy–Driven Performance Enhancement in Perovskite Oxides for Energy Conversion and Storage Systems

Carbon Energy, EarlyView.
High‐entropy perovskite oxides enable tunable structures and properties through multi‐cation disorder and entropy stabilization. This review summarizes advances in synthesis, structural and defect engineering, and their applications in OER/ORR, CO2RR, and electrochemical energy storage, highlighting in situ characterization and modeling that clarify ...

Catholyte‐Free Composite Cathodes Break the Energy Density Barrier of All‐Solid‐State Lithium Batteries

Carbon Energy, EarlyView.
All‐solid‐state lithium batteries (ASSLBs) with conventional catholyte‐based composite cathodes have a theoretical energy density limit of approximately 400 Wh kg–1 and 900 Wh L–1. The design of catholyte‐free composite cathodes can break this barrier and improve the theoretical energy density up to 500 Wh kg–1 and 1000 Wh L–1. ABSTRACT The gravimetric

Impact of A‐Site Sr Substitution in LaFeO3 on Syngas Selectivity During Chemical Looping Dry Reforming of Methane (CL‐DRM)

Chemistry – A European Journal, EarlyView.
Sr doping regulates oxygen exchange and methane activation in LaFeO3, suppressing nonselective CH4 cracking and coke formation during CL‐DRM. La0.7Sr0.3FeO3 provides the optimal balance, delivering ∼40% CH4 conversion, an H2/CO ratio of 2, and >95% carbon balance.

Iron and Nickel Substituted Perovskite Cobaltites for Sustainable Oxygen Evolving Anodes in Alkaline Environment

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

Resource‐Efficient Electrodes with Metallized Woven‐Glass‐Grid Current Collectors for Lithium‐Ion Batteries

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The use of metallized glass‐based woven‐grids instead of metal foils as current collectors for LIBs leads to a significant reduction in metal usage by over 90 % and weight savings of more than 80 %, resulting in an 11 % increase in specific energy at the cell level. Abstract A novel class of resource‐efficient, woven‐glass‐grid current collectors (CCs)
