Vanadium battery can lead the new energy revolution

Vanadium battery (VRB, VanadiumRedoxFlowBattery) is the world's largest and most technologically advanced, closest to the industrialization of high-performance reversible fuel cell with power, and large capacity, high efficiency, low-cost, long life, a series of unique green advantages, in wind power, photovoltaic power generation, peak shaving power grid, the distribution of power stations, military storage and transport of municipal, communication base stations, UPS power supply, etc. have an extremely broad field of application of good prospects in Japan, Canada, the United States, Australia, Western Europe and other countries and regions have begun to replace the capacity of small, short life of lead-acid battery pollution.
Vanadium 411462-421,hp pavilion dv2000 battery,hp pavilion dv6000 battery technology with the rapid development of vanadium battery is bound to bring to mankind an unprecedented, far-reaching significance of the new energy revolution!
The advantages of vanadium battery Power compared with other chemicals, vanadium battery has obvious advantages, the main advantages are as follows: 1. Power big: the battery by increasing the number of single-chip and electrode area, can increase the vanadium battery power, the current model of the U.S. commercial operation of the vanadium battery power has reached 6 MW.
2. Capacity: through the arbitrary increase in the volume of electrolyte can be any increase in the vanadium battery power, when more than up to giv'at; by increasing the concentration of the electrolyte can be doubled in capacity vanadium hp pavilion dv2500 battery,372772-001,pb994a, hp nc6110 battery , hp nc6120 battery.
3. Efficient: As the vanadium battery of high catalytic activity of the electrode, and positive and negative electrode active material were stored in the positive and negative electrode electrolyte storage tank, to avoid the positive and negative electrode active material of the self-discharge consumption, vanadium battery charge and discharge energy conversion efficiency above 75%, much higher than 45% of lead-acid batteries.
4. Long life: As the vanadium battery positive and negative electrode active material, respectively, only exists in the positive and negative electrolytes, the charge-discharge the battery when no other phase change often can not damage the battery depth of discharge, long battery life . At present, the commercialization of Canada VRBPowerSystems the longest running model vanadium battery module has been running more than nine years, the charge cycle life put more than 18,000 times, much higher than the fixed-type lead-acid batteries of 1000.
5. To respond to fast: the heap is full of vanadium battery electrolyte can be activated in an instant, in the operation of charge-discharge state switch only 0.02 seconds, in response to the speed of 1 ms.
6. Can be instantly recharged: the electrolyte can be achieved through the replacement of vanadium hp nc6140 battery , hp nc6200 battery , hp nc6220 battery , hp nc6230 battery charge moment.
7. Safe: vanadium battery without the potential risk of explosion or fire, even if the positive and negative non-hazardous mixed electrolyte, the electrolyte is only slightly elevated temperature.
8. Cost: In addition to ion-exchange membrane, the vanadium battery components for the low-cost carbon materials, engineering plastics, rich sources of material and easy recovery of precious metals for the electrodes do not need a catalyst, and low cost.
9. Vanadium hp nx6110 battery , hp nx6120 battery , hp nx6125 battery site degrees of freedom, and can be closed fully automatic operation, no pollution, easy maintenance, low operating costs.
Vanadium battery market China and the world market, respectively, vanadium battery is shown in Table 1, Table 2, in which wind power and photovoltaic power generation market demand vanadium battery capacity by the total volume (see Table 3 ~ 6) 25%, the other areas of the vanadium battery market demand by 100 % calculation; vanadium battery output 2 yuan / kW basis, non-electrolyte.
Wind power At present, the need for wind turbines with power equivalent to approximately 1 percent of its power of lead-acid batteries used in emergency situations to protect land Blade fan, and other needs of each aircraft is equipped with the Typhoon power equivalent to approximately 4 percent of its power back-up battery. As the grid has become a bottleneck in the development of wind power, with the explosion of wind power development, wind power and the grid will become more and more conspicuous contradictions, in order to reduce the impact on the power grid to improve the utilization of wind power at the same time earn large peak-valley difference grid, with wind power would require the equivalent power of 10 ~ 50% of the dynamic energy storage ibm thinkpad r40 battery,ibm thinkpad r32 battery. Off-grid power generation for the fan, you need a larger proportion of the dynamic energy storage batteries.
As the fan is now the existence of lead-acid batteries used in the capacity of small, short life, poor stability, the maintenance of time-consuming and laborious, serious pollution, such as defects, fan manufacturers are always looking for a better alternative to lead-acid battery products, I believe has many outstanding advantages The vanadium battery can replace the existing lead-acid batteries, and the dynamics of building a wind power energy storage system, greatly improve the efficiency of wind power and efficiency, and promote wind power industry to develop better and faster.
Photovoltaic power generation According to authoritative statistics, in recent years the global average annual growth rate of PV modules up to 30%, the development of photovoltaic industry become the world's one of the fastest growing new businesses. Especially in 2008, the world's total PV installed capacity of 3 GW. As its name implies, solar photovoltaic power generation needs, once at night and on rainy days, made no electricity, thus the need for batteries for the storage of electricity, as a result of lead-acid 02k6928 , 02k7052 , 02k7053 , 02k7054 power, capacity, life expectancy are very limited, I believe that sets a number of outstanding advantages in the vanadium Photovoltaic cells will serve as the preferred energy storage battery.
