Digital battery

Recently, the vanadium KD186 NF343 battery is subject to heated debate, supporters believe that the vanadium battery has a green, long life and other devices, with the rapid development of technology that will make a human being without precedent is a importance and scope of new energy industrial revolution. Opponents argue that only research institutions, as well as the vanadium battery are very beautiful blown foam, the sole purpose of financing needs. Finance Street EP after study has revealed that although the area of the vanadium battery is there are many problems, but it has the potential to undermine the process of past human use of energy, it is good to look forward.

 

Development of vanadium battery

Vanadium redox batteries (VRB, VanadiumRedoxFlowBattery) is the largest and most technologically advanced, closer to the industrialization of fuel cells, high performance reversible, with a great power, high capacity, high efficiency, low cost, a long life and a series of unique green benefits of wind energy, photovoltaic energy, energy peaks, distributed power generation, electrical storage military vehicles of municipal services, base station communication , power supplies UPS has a very wide field of good prospects in Japan, Canada, the United States, Australia, Western Europe etc. countries and regions have begun to replace the capacity of small, short life, pollution, advance considerable acid batteries.

Compared to other food chemicals, vanadium battery has obvious advantages, the main advantages are:

1. Big Power: increasing the number of single cells and the area of the electrode, you can increase the power of the vanadium battery, the commercial demonstration of American power in the vanadium battery is running has reached six megawatts.

2. High capacity: an increase in the volume of electrolyte, you can arbitrarily increase the power of the vanadium battery until gigawatt hours or more, increasing the concentration of electrolyte, you can multiply the power of vanadium batteries.

3. The efficiency is high: When the vanadium battery electrode high catalytic activity, and positive and negative electrode active material were stored in the storage tank positive and negative electrolyte, preventing the material of positive electrode and negative Active use of self-discharge battery vanadium and discharge energy conversion efficiency up to 75% or more, much more that 45% of battery lead acid. hp OmniBook XE3 battery  hp Pavilion dv8000 battery

4. Long life: When the vanadium battery positive and negative active material to exist only in the positive and negative electrolyte, charge and discharge the battery when no other phase-change policy, can not damage the battery deep discharge, long battery life. Canada Now VRBPowerSystems longest commercial demonstration module vanadium battery has worked more than 9 years, the charge-discharge cycle life of more than 18,000 times, much higher than the lead acid type fixed battery 1000 times .

5. Speed of response: the heap is full of electrolyte battery of vanadium could be launched at a moment in the process of filling and operation requires the execution of only 0.02 seconds to turn the state, response time 1 ms.

6. Perhaps snapshot: the electrolyte can be achieved by replacing the battery Vanadium instantaneous load.

7. High security: vanadium battery, without the potential risk of explosion or fire, although the mixture of positive and negative electrolytes is also non-hazardous, but the temperature of the electrolyte was slightly increased.

8. The cost is low: In addition to ion-exchange membrane, components of the vanadium battery, the cost for most materials at low cost carbon, engineering plastics, materials, sources of wealth, easy retrieval, not of precious metal catalysts as electrodes, and low.

9. Vanadium battery location large degree of freedom can be fully automated transaction closed, no pollution, easy maintenance, operating costs low. Sony VGP-BPS8 Sony VGP-BPS8A

 

World and China’s battery Vanadium view of the market in recent years will continue to maintain a relatively rapid pace of growth, market prospects are very good. More precisely from the data, estimated that by 2010 the world market for vanadium batteries will reach 1.075 trillion yuan, up 74.8% over 2008, while in 2020 the size reaches 7 25 trillion yuan, against a growth of 574.42 percent in 2010. From the Chinese perspective, 2010, China’s battery market vanadium reach 527.5 billion yuan, growing 39.22% over 2008, while in 2020, the size will reach 1.63 trillion yuan more in 2010 rose to 209%.

 

Investment value of vanadium battery

With wind, solar and other clean resources, extensive use of its power generation does not become an obstacle to the stability of defects are a major obstacle to the development of its depth. If there is no great capacity, a storage device to provide secure support for the development of clean energy is an empty word. Storage devices in the clean energy sector as a whole is a very important link in the chain, while the vanadium battery for his own benefit in the future development of devices for energy storage will play an important role.

Vanadium battery is a strong growth momentum, a green battery excellent, it has a particular cellular structure, depth of discharge at high current density, load quickly, high energy, low cost, in the large scale storage in lithium-ion energy, Ni-MH unmatched price-performance advantage. And manufacture of complex and expensive compared to fuel cells, both in the large-scale storage of energy, or application prospects vehicle power, the vanadium battery is more competitive force can be used as production systems to support clean solar energy storage devices for energy for hybrid and electric cars. In addition, the scope of the internal battery of vanadium is still in the market are not in the marketing process is required to have a number of investment opportunities.

 

At the same time promote the use of vanadium batteries in line with current government energy-saving emission reduction strategy advocated by a national scale. Vanadium battery for its efficiency of energy conversion, storage capacity of electricity, operational safety and environmental benefits such as friendly to allow the final energy consumption of China, fundamental changes have occurred, you can achieve greater energy efficiency, conservation of existing energy resources and reduce pollution, and ultimately to achieve energy savings targets for reducing emissions.

In addition, the location of China’s commercial technology batteries Vanadium achieved a major breakthrough has been that a number of key core technologies have complete independence of intellectual property rights, the vanadium battery that provides investment significant technical support. Here we have common prefecture-level cities in China, for example, if the peak value of about 500 million kilowatts will be 10 hours of peak power of the all-vanadium battery Duan Duan Gu Energy Supply energy storage.

 

However, the need to remind investors to note that does not mean that there is technically no problem. For example, first, the cathode of battery vanadium vanadium pentavalent liquid at temperatures above 45 degrees Celsius, or put aside for the case of precipitation of vanadium pentoxide easily precipitate precipitation precipitation plug flow channel, the Felt carbon fiber coating, deterioration of electrical performance of the reactor until the battery disposal, while the stack in the long term the process temperature of the electrolyte can easily exceed 45 degrees Celsius. Secondly, the graphite plate etching liquid to be positive if the user is working properly, the graphite sheet can be used for two years, if the user misuse, a charge will be able to complete the burning graphite plates The battery can not be discarded. Under normal circumstances of use, every two months by a professional should conduct an interview, the maintenance costs of such a fund with high frequency, effort.

In addition to technical issues, the vanadium battery problems, it is still too expensive. With a battery of five kilowatts, for example, (a cube electrolyte, 1.8mol / L) 17 million control system 10 million euros, divide 70000, chassis 40000, the graphite plates 15,000, 07000 pump, carbon estimated 04000, a total of 406,000 is the cost of core subjects, but does not include the cost of secondary materials and labor costs. Thus, five kilowatts of vanadium batteries cost more than 400,000 higher than the cost of the same size lead-acid repeatedly. The vanadium battery popularize provide significant barriers.
