Cobalt‐Free Single‐Crystal Cathodes for Next‐Generation Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cobalt‐free single‐crystal cathodes enhance lithium‐ion battery stability by mitigating fracture, degradation, and phase transitions. This review highlights Ni‐rich layered, Li‐Mn‐rich, spinel, and olivine frameworks, synthesis strategies enabling morphology and defect control, and structural tuning via doping and coatings, offering pathways toward ...

Mitigating Structural Degradation in Hydrated V2O5 for Proton Batteries through Nanoconfinement with a Holey Graphene Matrix

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
HrGO‐supported and confined water‐assisted synergy for faster proton transport in the V2O5 resulted in ultra‐long life over 10 000 cycles at high current density of 1 A g−1. A reaction kinetics study of the ultra‐long cyclability via first principle DFT calculation is also presented. Proton‐based electrochemistry offers a promising solution to the cost

Strong Nonradiative Recombination Induced by Pronounced Lone‐Pair Electron Expression Following Deprotonation in Aziridinium Lead Iodide Perovskites

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The transition from linear to cyclic organic cations promotes deprotonation and activates VH(N) defects with pronounced lone‐pair electron activity, thereby inducing severe local distortions and highly efficient nonradiative recombination centers. This work unveils a direct structure–defect–performance correlation and proposes design strategies for the
