Vanadium Redox Flow Battery

概述

The vanadium redox flow battery (VRFB) uses four oxidation states of vanadium (V²⁺/V³⁺ and VO²⁺/VO₂⁺) in two electrolyte tanks. During discharge, V²⁺ is oxidized to V³⁺ at the negative electrode while VO₂⁺ is reduced to VO²⁺ at the positive electrode. Using the same element eliminates cross-contamination.

日常示例

Large VRFB installations store renewable energy from wind and solar farms, releasing it when the sun is not shining or wind is not blowing.
