Abstract
En 中文
• Interconnected 1D carbon nanotubes construct a 3D conductive framework for rapid electron transport. • Optimal V2O3 loading balances active sites and conductive network for enhanced kinetics. • The hierarchical mesoporous structure shortens Zn2+ migration pathways and promotes pseudocapacitive storage. • Optimized vanadium-carbon ratio balances electronic conduction, ion transport, and structural stability. • Kinetic analysis elucidates the diffusion-controlled and pseudocapacitive dual charge storage mechanism.
