Description

technical field [0001] The invention relates to the technical field of vanadium batteries, in particular to a non-metallic electrode material for a vanadium battery and a preparation method thereof. Background technique [0002] The vanadium battery is called a vanadium redox flow battery (Vanadium Redox Battery, abbreviated as VRB), which is a redox battery in which the active material is in a circulating liquid state. In work, vanadium battery is a secondary energy system that utilizes redox reactions between vanadium ions in different valence states for energy storage and conversion. Its characteristics are: no emission pollution, adjustable capacity, long cycle life, deep high current density discharge, fast charging, and high energy conversion rate. Therefore, it is widely used in systems such as power station peak regulation, large-scale photoelectric conversion, energy storage for wind power generation, uninterruptible power supply, and emergency power supply.
