16.4. Key materials for vanadium batteries The key materials for vanadium cells include the vanadium electrolyte, membrane, and electrodes. Strict technical control and testing of these components are required during their preparation. 16.4.1.
Vanadium batteries are also compatible with the wide geographical distribution and large number of solar cells used in network communication systems. They can replace the lead–acid batteries commonly used in the current solar power systems, while reducing maintenance requirements and costs and increasing productivity. 16.3.2.5.
Electrolyte materials Initially, the vanadium battery electrolyte was made by dissolving VOSO 4 directly in H 2 SO 4. However, due to the high price of VOSO 4, the field began investigating other vanadium compounds, such as V2 O 5 and NH 4 VO 3. Currently, there are two methods to prepare the electrolyte: mixed heating and electrolysis.
In this book, vanadium-based electrode materials are divided into four kinds based on their structure features and electrochemical characteristics: oxygen-free vanadium-based compounds, vanadium phosphates, vanadates, and vanadium oxides (Fig. 1.5). Classification of vanadium-based electrode materials.
Turbines currently use lead–acid batteries, with small capacity, short lifetime, poor stability, laborious maintenance, and high level of pollution. Hence, vanadium batteries can provide significant advantages and could completely replace the existing lead–acid batteries as the main body of dynamic wind energy storage systems.
With increasing maturity of the technology, vanadium batteries are constantly adapting to different energy storage requirements. In March 2001 the Institute of Applied Energy installed a stable vanadium battery system for storing wind turbine output of AC 170 kW×6 h.
