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

ENERGY &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

Bottlenecks‐Breaking in Zinc‐Iodine Batteries Toward Practical Implementation: A Review and Perspective

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aqueous zinc–iodine batteries (Zn–I2Bs) offer promise for grid storage due to safety and cost advantages yet face critical bottlenecks: severe self‐discharge (polyiodide shuttling and HER), limited energy density, sluggish kinetics, and zinc anode instability.

Monodisperse High‐Entropy Metal Oxide Nanoparticles Encapsulated Within 2D Porous Carbon Sheets for Enhanced Catalytic Activity in Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study synthesizes monodisperse oxide nanoparticles with abundant ionic vacancies encapsulated in 2D porous carbon sheets via pyrolysis of a high‐entropy precursor, constructing a cross‐scale catalytic interface. It enables Li‐S batteries with a high capacity of 761 mAh g−1 at 3 C and retains 80.44% capacity after 1000 cycles at 1 C.

Mitigating Cathodic Challenges in Aqueous Zn–I2 Batteries via Dual‐Effect Function Strategy: Concurrent I3− Immobilization and Catalysis of I0/I− Redox Kinetics

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work employs a dual‐effect function strategy of Se to make an original composite material of selenium (Se) and activated carbon (AC) (designated as Se–AC), as a functional iodine‐adsorbed cathode host. Not only Se catalyzes the I0/I− conversion reaction, but also Se nanoparticles can adjust the charge distribution of AC to adsorb more I3−. Aqueous‐

CeO2/Co3O4 p‐n Heterojunction as a Photo‐Responsive Bifunctional Electrocatalyst for Efficient Zinc‐Air Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A photo‐responsive bifunctional electrocatalyst with CeO2/Co3O4 p‐n heterojunction has been designed and exhibited excellent photo‐enhanced ORR/OER performance and Zn‐air batteries performance. The introduction of semiconductor materials as bifunctional oxygen reduction/evolution reaction (ORR/OER) electrodes has been proved as an efficient way to ...
