Overview of Research Progress and Development of Cathode Materials for Aqueous Na‐Ion Batteries

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Aqueous sodium‐ion batteries (ASIBs) have now been viewed as the promising energy storage technique for the grid application due to their intrinsic safety and cost‐effectiveness. However, their energy density and cycling stability are still unsatisfactory accompanied by the narrow electrochemical stability window of water and parasitic side ...

Unveiling the Mechanism of V6O13/MnO2 Heterojunction for High‐Performance Aqueous Zinc‐Ion Batteries via Combined Experiments, DFT, and Deep Learning

open access: yesCarbon Energy, EarlyView.
Preparation process, cycling performance, and deep learning‐predicted cycling performance of the V6O13/MnO2 heterojunction. ABSTRACT Aqueous zinc‐ion batteries (AZIBs) suffer from sluggish diffusion kinetics and poor structural stability. Single‐phase V6O13 exhibits a high Zn2+ diffusion barrier (~0.55 eV), while MnO2 suffers from rapid capacity fading
