Vanadium battery, also known as all-vanadium ion redox flow battery (VFB for short), is divided into two parts, the stack and the electrolyte, which are relatively independent. Electric energy, the electrolyte circulates during operation. It does not produce harmful substances during use, and is a new type of green battery. The battery structure is special and has the incomparable advantages of traditional batteries:
◆Power and capacity are independent of each other and can be flexibly configured according to user needs;
◆SOC can be accurately monitored in real time, providing accurate basic data for operation scheduling;
◆Long cycle life, much higher than traditional secondary batteries;
◆High-rate charge and discharge capability, fast charge and discharge;
◆The charging and discharging state can be changed quickly at will, without memory effect or other adverse effects;
◆Battery balance is automatically realized through electrolyte circulation, the management system is simple, and the design and manufacture of large systems are easy
◆Low lifetime cost and easy maintenance;
◆High safety and reliability, environmental protection and no pollution, great freedom of location selection.
