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

Carbon 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
