China will have high-capacity super capacitor research and development capabilities

What is a super capacitor? Liu Youmei, academician of the Chinese Academy of Engineering and director of the expert committee of CSR Zhuzhou Machinery Co., Ltd., told reporters that in layman's terms, it was the third generation of energy storage devices. The first generation was mechanical energy storage, such as flywheels and springs, and the second generation was chemical energy storage. Such as lead-acid batteries, nickel-metal hydride batteries, lithium batteries, etc.; and the third generation is a physical type of energy storage devices represented by super capacitors.

"The number of charging times is less than 10,000 times, the charging time is up to several hours, and there is a risk of explosion and contamination of the environment" vs "1 million times, dozens of seconds, no pollution, and explosion risk."

The vice director of the technical center of CSR Zhuzhou Machinery Co., Ltd., and Dian Dianbo, director of the Ningbo Supercapacitor Research Institute, used a set of comparative images to demonstrate the advantages of supercapacitors compared to traditional chemical energy batteries.

What is the scope of application of this product? According to Dian Dianbo, it can be widely used in consumer electronics, rail transit, urban public transportation systems, national defense and aerospace, energy recovery of cranes, power generation and smart grids.

For example, Dian Dianbo said that, for example, at present, a crane crane at a port uses hundreds of tons of containers to consume a large amount of electric energy, and its energy when it is dropped is basically consumed by a resistor device. If a super capacitor is used for potential energy conversion The recovery of electrical energy can achieve up to 80% of electrical energy recycling and reuse, and its green, energy-saving and environmental protection effects are quite outstanding.

In view of the superior green, energy-saving and environmental-friendly advantages of supercapacitors, South Korea, the United States, Japan, and other countries have conducted extensive research work on supercapacitors in recent years. At present, there are more than a dozen supercapacitor manufacturers in the world and can provide various types of Super capacitor products.

China began to develop supercapacitors in the 1990s. In recent years, companies represented by China South Locomotive have achieved a series of inventions and innovations in the fields of structural design, material preparation, device processing, and system integration of supercapacitors and have independent intellectual property rights. The key bottleneck that has constrained the development of supercapacitor technology has been broken through, breaking the foreign technology blockade, and making China one of the few countries in the world that has high-capacity super capacitor research and development capabilities.

Plastic Blind Ditch, main effect is Ooze water in soil. To reduce the pressure of groundwater, eliminate redundant water, protection building won't demage because of Seepage deformation. Widely used in Underground drainage engineering of civil, transportation, water conservancy, civil miners and environmental protection project Underground drainage engineering

 

Product features:

plastic blind ditch is made from many Root modified plastics silk which have same toughness. It is impossible to be staved. With the pressure 250 kpa , Section air void still more than 60%, even on the tremendous pressure, always exist out water space, there are still 10-15% of the pore, and good resilience;

Average surface opening rate of plastic blind ditch reached 90-95%, much more higher than other similar products. To most effectively collecting soil of the seepage, and timely eduction;

plastic blind ditch made by filter membrane from Corrosion fiber and modified polyethylene 3 d mesh, never degradation in in the soil or water, try to be anti-aging formula, can Maintain permanent material without change

filter membrane of plastic blind ditch can be selected according to the different soil conditions, fully meet the needs of engineering, and avoid the old products filter membrane single faults.

plastic blind ditch is light, the construction and installation is very convenient, construction efficiency is greatly accelerated.
