Harnessing Carbon‐Containing Materials for Next‐Generation High‐Temperature Electromagnetic Wave Absorbers

open access: yesCarbon Energy, EarlyView.
Traditional carbon materials show limited high‐temperature oxidation resistance, which becomes pronounced above 673 K and significantly restricts their practical applicability. To address this challenge, enhancing polarization loss and leveraging its negative temperature dependence to offset the temperature‐induced increase in conductance loss are ...

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
