The vanadium redox battery (VRB) is a mobile battery is gradually entering the commercialization stage. VRB energy storage technology as a chemical, compared to traditional lead-acid batteries, nickel cadmium batteries, it is designed to have many unique performance is also applicable to a variety of industrial applications, for example, can replace the oil machine, spare power supplies. Use of the design and manufacture of VRB VESS (VanadiumEnergy Storage System, vanadium energy), its design and operating characteristics in the VRB’s based on the optimization, and integrated intelligent control and operation of electronic devices for management of many automated. Simply put, the vanadium redox battery energy will be stored in the electrolyte is converted to electrical energy, which is achieved through the electronic exchange between the two different types of vanadium, separated by a membrane. The electrolyte is a mixture of sulfuric acid and vanadium, acid and traditional lead-acid batteries. Since this is reversible, so the VRB battery can either charge, can also discharge. The charge and discharge, with the two kinds of vanadium ion concentration, power and energy conversion. The VRB battery consists of two electrolyte pools and layers of the battery unit. Electrolyte pool for two different Sheng electrolyte. Each battery unit consists of two “half unit”, sandwiched between the diaphragm and the electrodes used to collect the current Two different “half unit” is in full bloom with the electrolyte of different ionic forms of vanadium. Each electrolyte pool with a pump for each “half-cell electrolyte transport in closed pipes. When charged electrolyte flow in the layers of the battery unit, electronic flow to the external circuit, which is the discharge process. When electronic transmission to the internal battery from the outside, the reverse process occurs, and this is charged to the electrolyte in the battery cell and then pumped back to the electrolyte pool. In the VRB, the electrolyte flow between multiple battery cell, the voltage of each cell voltage in series formed. The nominal voltage is 1.2V. Current density collected by the current in the battery unit surface area of ​​the decision, but the current supply depends on the flow of electrolyte between the battery cell, rather than the battery layer itself. The VRB battery technology is one of the most important features are: peak power depends on the cell layer of the total surface area, while on battery power depends on the electrolyte. In traditional lead-acid and nickel-Fu battery electrode and electrolyte is placed in a piece of power and energy is strongly dependent on the capacity of the plate area and electrolyte. VRB battery is not the case, the electrode and electrolyte does not have to be placed in a, which means that energy storage can be exempted from the limitations of the battery casing. Power in terms of different levels of energy for the cell layer of the battery unit or groups of units by providing sufficient electrolyte to get. Layer charging and discharging the battery does not necessarily require the same voltage. For example, the VRB battery can use the series battery voltage discharge, charging can be in another part of the cell layer with a different voltage.
