Mechanistic Origin of Capacity Limitation in Sidorenkite‐Type Na3‐xFe(PO4)(CO3) Carbonophosphate Cathodes for Na‐Ion Batteries

Advanced Energy Materials, EarlyView.
The potential–capacity profile reveals a one‐electron limitation in sidorenkite Na3−xFe(PO4)(CO3). Structural analysis shows that Fe4+ formation induces lattice strain and suppresses electronic conductivity, blocking further Na extraction. These findings establish key design rules: preserve crystallinity, avoid Jahn–Teller–active d4 configurations, and

“Lithium‐Free” Anode Solid‐State Batteries Enabled by 3D Structured Miec Garnet

Advanced Energy Materials, EarlyView.
“Lithium‐free” anode solid‐state batteries can maximize energy density by eliminating excess lithium metal but are limited by unstable lithium nucleation and poor lithium reversibility at solid interfaces. A mixed ionic and electronic conducting garnet scaffold promotes uniform lithium deposition within a three‐dimensional porous framework at low ...

Unlocking Three‐Dimensional Electron and Ion Transport in High‐Loading and Dense Lithium‐Ion Battery Electrodes Assisted via Porous Graphene Networks

Advanced Energy Materials, EarlyView.
Graphene mesosponge (GMS) enables three‐dimensional electron and ion transport in high‐loading, densely packed lithium‐ion‐battery electrodes through its unique mesoporous structure. The three‐dimensionally interconnected carbon network and electrolyte retained within the GMS mesopores ensure efficient electronic and ionic conduction, respectively ...

Calendering‐Dependent Electrochemical and Cost‐Energy Tradeoffs in Layered – Olivine Blend Cathodes

Advanced Energy Materials, EarlyView.
Blends comprised of LiNi0.9Mn0.05Co0.05O2 (NMC) and LiMn0.7Fe0.3PO4 (LMFP) are investigated to assess the performance – cost tradeoffs. Their rate‐capability benefit is retained only under uncalendered‐to‐moderately calendered states. Although blends reduce voltage decay and improve energy retention, they do not deliver measureable improvement in ...

Near‐Micron Single‐Crystalline Mn‐Rich Cathodes With Exceptional Cycling Stability

Advanced Energy Materials, EarlyView.
Earth‐abundant single‐crystalline Mn‐rich DRX material faces a synthetic limit in particle‐size reduction. Our automated TEM workflow reveals interparticle compositional heterogeneity in early‐stage DRX, which forms minor orthorhombic impurities during cooling and necessitates prolonged annealing.

Redox‐Modulated σ‐Bond Reactivity in a Radical‐Anion Dimer

Angewandte Chemie, EarlyView.
A radialene‐based radical anion σ‐dimer comprising an elongated C‐C bond exhibits orthogonal stimuli responsiveness. Homolytic cleavage of the dimer to the radical state is triggered by mechanical strain and high temperature. Dimer scission is also achieved via oxidation, resulting in formation of neutral radialenes.
