Vanadium batteries (all-vanadium flow batteries) are a type of liquid flow battery that uses vanadium ions in different oxidation states as charge carriers and achieve energy storage and release through the redox reactions of vanadium ions in the electrolyte.
Advantages:
Low cost: The core material is an alum compound (abundant in reserves and low in price), without reliance on precious metals.
High safety: The electrolyte has no flammability, and there is no risk of explosion or fire during charging and discharging, with strong environmental adaptability.
Long cycle life: The theoretical cycle count exceeds ten thousand times, far superior to lithium batteries, and has outstanding cost-effectiveness for long-term use.
Environmentally friendly and pollution-free: The materials can be recycled, and the production and disposal processes have little impact on the environment.
Disadvantages
Low energy density: approximately 20-40 Wh/kg, only 1/5 - 1/10 of that of lithium batteries, with larger volume and weight.
Slow charging and discharging speed: low ion migration efficiency, not suitable for scenarios requiring rapid energy replenishment (such as electric vehicles).
Complex system: requires pump, pipelines and other electrolyte circulation equipment, which is not conducive to miniaturization applications.
