China's car successfully developed the world's highest level of supercapacitors
Three times the power increase, the use of more efficient use of energy, can be used longer, October 9, from China Zhuzhou Electric Locomotive Co., Ltd. (China Railway Machine Co., Ltd.) came the news, self-developed a new generation of high-power Graphene super capacitor come out.
The company released the news, "3 V / 12000 Farah graphene / activated carbon composite electrode supercapacitors" and "2.8 V / 30000 Farah nano-hybrid nano-capacitors" in Zhejiang Province Science and Technology Achievement and New Products Identification Conference, was identified Performance indicators for living in the leading international level. Depending on capacity and rated operating voltage, a 3 V / 12,000 Farad supercapacitor can be fully charged in 30 seconds and a 2.8 V / 30,000 Farad supercapacitor charges in 1 minute. Compared to activated carbon supercapacitors, graphene / activated carbon composite electrode supercapacitors more energy, longer life expectancy.
Chinese Academy of Engineering Yang Yusheng, Liu Youmei and "National 863 Energy Saving Project" expert Professor Zhang Shichao and other experts unanimously identified: 3 V / 12000 Farah super capacitor and 2.8 V / 30 000 Farah super capacitor represents the world's super capacitor monomer technology The highest level of technology research and development continue to walk in the forefront of the world.
It is reported that the super capacitor is a typical physical energy storage device, charging device than the traditional incomparable advantages. Charging 10,000 times, charging time up to several hours, the risk of explosion and pollution of the environment "VS" 1000000 times, tens of seconds, pollution-free and the risk of explosion. " Vice President of the Technology Center of China Railway Car Corporation and Ruan Dianbo, director of Ningbo Supercapacitor Research Institute, used a series of contrasting images to make a presentation. Ruan Dianbo said super capacitor can be widely used in consumer electronics, rail transit, urban bus system, national defense and aerospace, crane potential energy recovery, power generation and smart grid and other fields.
Currently, supercapacitors are widely used and representative in trams and trolley buses. China's Zhongchuangchuang company developed 9500 Farah, 7500 Farah and many other super capacitors have been widely used in Guangzhou, Ningbo, Wuhan, Huai'an, tram and 196 trolleybus in Ningbo City. Guangzhou Supercapacity, which has been operating for more than six months, is a perfect fusion of Guangzhou Tower and Pearl River. It has become a bright business card in Guangzhou City and is warmly welcomed by people from all walks of life.
3 Volt / 12000 Farad Supercapacitors are suitable for the main drive of the tramcar. The single-charging mileage is up to 6 km with zero emission characteristics, saving over 30% of the energy consumption of the tram. At present, there are 5,000 km of planned tramways in the country and 2,500 km in 2020. If all the trams use this super capacitor as the main driving power, 219 million kWh of electricity can be saved each year and 2.5 million tons of carbon dioxide emissions will be reduced.
2.8 V / 300 Farah supercapacitors suitable for trolley bus master drive, single charge mileage can be increased from the current 4 to 6 km to 8 to 10 km to achieve the vehicle only at the end of the site charging requirements, but also with charge Discharge speed, long cycle life advantages. Currently, about 60,000 bus buses are updated annually in mainland China. If all the supercapacitors are used as the main driving power source, the annual energy saving will reach 584 million kWh and the emission of carbon dioxide will be reduced by 6.7 million tons.
