It only takes 2 seconds to charge the mobile phone, and it takes more than 20 seconds to charge the energy-storage light rail train. This is the magic function of the super capacitor. Today, the Chinese have firmly occupied the heights of this world's cutting-edge technology.
On September 12, the news came from China CSR Zhuzhou Electric Locomotive Co., Ltd., the world's largest power supercapacitor monomer (7500F) independently developed by Ningbo CSR New Energy Technology Co., Ltd., its subsidiary, successfully achieved mass production. The first batch of 5000 7500F Super capacitor products have been delivered to users.
What is a super capacitor? Liu Youmei, academician of the Chinese Academy of Engineering and director of the Expert Committee of China South Locomotive and Rolling Stock Co., Ltd., introduced it as a third-generation energy storage device. The first generation is mechanical energy storage, such as flywheels and springs; the second generation is chemical energy storage, such as Lead-acid batteries, nickel-metal hydride batteries, lithium batteries, etc .; and the third generation is a physical energy storage device represented by super capacitors.
"Within 10000 charging times, charging time of several hours, there is a risk of explosion and environmental pollution" VS "1 million times, tens of seconds, no pollution and explosion risk" Ruan Dianbo, deputy director of CSR Zhuji Machinery Technology Center and director of Ningbo Supercapacitor Research Institute, used a set of comparative images to demonstrate the advantages of supercapacitors compared to traditional chemical energy batteries. According to Ruan Dianbo, it can be widely used in consumer electronics, rail transit, urban public transportation systems, national defense and aerospace, lifting potential energy recovery, power generation and smart grid.
Ruan Dianbo gave an example. For example, the current cranes in the port consume a large amount of electrical energy when lifting hundreds of tons of containers at a time, and the energy when they are dropped is basically consumed by resistance devices. If supercapacitors are used for potential energy conversion The recovery of electric energy can achieve up to 80% of electric energy recovery and reuse, and its green, energy-saving and environmental protection effects are quite outstanding.
In view of the superior green, energy saving and environmental protection advantages of supercapacitors, in recent years, South Korea, the United States, Japan and other countries have carried out a lot of research work on supercapacitors. At present, there are more than a dozen supercapacitor manufacturers in the world that can provide a variety of types. Super capacitor products.
China has been developing supercapacitors since the 1990s. In recent years, companies represented by CSR have made a series of inventions and innovations in the fields of supercapacitor structural design, material preparation, device processing, system integration, and have independent intellectual property rights. Breaking through a number of key bottlenecks restricting the development of supercapacitor technology, breaking the foreign technical blockade, making China one of the few countries in the world with high-power supercapacitor research and development capabilities.
At present, many cities in China are communicating with China CSR Zhuji Corporation to develop and use green intelligent products such as 100% low-floor trams and city buses that use super capacitors as the main power source.
In view of the application value of supercapacitors, led by CSR Zhuji Corporation, Qingdao Institute of Bioenergy and Process, Chinese Academy of Sciences, Institute of Chemical Materials, Chinese Academy of Engineering Physics, Nanjing University of Technology and other units participated in the "high specific energy, low cost Research on the key technology of the new supercapacitor ", as a sub-project of the key technology research theme project of high-performance chemical energy storage batteries and demonstration power stations, participated in the national" 863 "plan.
Silicone rubber tape is made of high temperature resistant adhesive tape adhesive inorganic silicone rubber tape is attached with easy peel protection layer, can be used in class H high temperature 250℃ (365°F), especially suitable for adding the outermost layer of cable terminal, can resist electric mark.
When Self Fusing Insulation Tape be sued, the end is covered with overlapping tape head, the entire end from the cable shell one inch to the metal protrusion, and another layer of semi-overlapping tape. When wrapping the Self Fusing Electrical Tape, gently exert force (can make the tape have 10%-100% elongation).
The last circle of the tape should not be stretched. In order to prevent the tape from warping away from the end, hold the tape until it is self-melting and stick (do not use water and dust).
