The information of GEFC-125V200A2h-VRB Vanadium Redox Battery


GEFC-125V200A2h-VRB Vanadium Redox Battery 
GEFC-125V200A2h-VRB Vanadium Redox Battery decription :
The practical application advantages.
Stack separated as a place to react with the electrolyte storage tank, fundamentally overcome the traditional battery self-discharge phenomenon. Power depends only on the size of the stack, the capacity depends only on the electrolyte reserves and concentration, the design is very flexible; when the power is certain to increase storage capacity, only need to increase the electrolyte storage tank volume, or improve the electrolyte volume or concentration can, without having to change the stack size; “instant charge” through the electrolyte to replace or add state-of-charge. Can be used in the construction of a kilowatt to 100 megawatt energy storage power plant, and adaptable.
Second, the charge and discharge performance is good, can be high-power charging and discharging, and can also allow the float and the depth of discharge. For lead-acid batteries, the greater the discharge current, the shorter the battery life; the deeper depth of discharge, the shorter the battery life. The vanadium battery depth of discharge 100%, nor will the battery impact. And the vanadium battery is less prone to short-circuit, which avoids the explosion and other safety problems caused by short circuit.
Third, the charge and discharge times theoretically life countless times. Charge and discharge time ratio of 1:1, while the lead-acid battery is 4:1. And the vanadium battery charge, put switch fast response, less than 20 milliseconds, is very conducive to the balanced power supply.
High energy efficiency DC-DC energy efficiency can reach more than 80%, while only about 60% of lead-acid batteries. Each unit battery status in the vanadium battery pack is basically the same, easy to maintain.
Location freedom, small footprint, the system can be fully automated closed operation, does not produce the mist, there is no acid corrosion. The electrolyte can be repeated use of non-emission, simple maintenance, low operating cost. Is a green energy storage technology. For renewable energy generation, the vanadium battery is the ideal substitute of lead-acid batteries.
Advantages of vanadium battery
Compared with other chemical power, vanadium battery has obvious advantages, the main advantages are as follows:
Power: by increasing the number of single cells and the electrode area, you can increase the power of the vanadium battery, the current U.S. commercial demonstration run of the vanadium battery power reached 600 MW.
Capacity: by arbitrarily increasing the volume of the electrolyte can be any increase in the vanadium battery can Daji Wa above; can be doubled by increasing the concentration of electrolyte, vanadium battery.
High efficiency: the vanadium battery electrodes with high catalytic activity, and positive and negative electrode active material is stored separately in the positive and negative electrolyte storage tank, to avoid positive and negative active material of the self-discharge consumption, vanadium battery charge and discharge energy conversion efficiency up to 75%, much higher than 45% of the lead-acid batteries.
(4) long life: the vanadium battery positive and negative electrode active material, respectively, only the phase change in the positive and negative electrolytes, charging and discharging the other battery often creatures, depth of discharge without damaging the battery, long battery life . Vanadium battery modules commercial demonstration of VRBPowerSystems, Canada is the longest running normal operation for over nine years, the charge-discharge cycle life of more than 18,000 times, much higher than the 1000 fixed lead-acid batteries.
5 fast response: the vanadium battery pile filled with the electrolyte can be started in an instant, the switch only takes 0.02 seconds to run the process of charging and discharging state, the response speed of 1 ms.
6. Instant charge vanadium battery charging instant: by replacing the electrolyte can be achieved.
Safety: vanadium battery potential explosion or fire hazard, even if the positive and negative electrolyte mixed non-hazardous, but the electrolyte temperature is slightly higher.
Low cost: In addition to the ion-exchange membrane, the vanadium battery components for low-cost carbon materials, engineering plastics, rich sources of material, easy recovery, does not require precious metals for the electrode catalyst, and low cost.
The vanadium battery site degrees of freedom can be fully automated closed operation, pollution, easy maintenance, low operating costs.
New applications of vanadium
The vanadium battery is a strong development momentum outstanding one of the green battery (which manufacture, use and waste process is not harmful substances), it has a special cell structure, the depth of the high current density discharge; charge quickly; higher than the energy ; low price; a very broad field of applications: such as buildings, airport, program-controlled switching station standby power; can be used as supporting energy storage for solar and other clean power generation systems; to provide electricity for submarines, ocean-going vessels and used for peak shaving.
