金属氧化物催化剂用于钒液流电池的研究进展OA

Vanadium redox flow batteries(VRFBs)have emerged as a pivotal technology for large-scale energy storage due to their high safety and long cycle life.The performance of electrode materi-als directly determines the overall battery efficiency,yet conventional carbon-based electrodes face challenges such as poor hydrophilicity,insufficient active sites,and sluggish reaction kinetics.Metal oxide-modified carbon-based electrode materials,as an effective optimization strategy,have garnered significant attention.Metal oxide catalysts not only offer advantages like low cost and diverse variet-ies but also exhibit strong oxidation capabilities,making them ideal candidates for enhancing elec-trode performance.This paper reviews recent research progress on metal oxide-modified electrodes in VRFBs,systematically classifying different types of metal oxide catalysts based on elemental group similarities and atomic counts.Furthermore,it analyzes the catalytic mechanisms and performance of various catalysts,while providing perspectives on future research directions for electrode materials and catalysts.
