Liu Zhaoping won the Million Award for the Entrepreneurship Plan Competition with "Graphene Industrialization Technology". He is accepting the award ceremony host to interview the electric car sold in the market. It takes 150 hours to charge at least 150 hours, which is too time consuming. "If you use a graphene-powered lithium battery, you can complete the charging in 10 minutes without damaging the battery life." Yesterday, Liu Zhaoping, a native of Jiangxi, returned to China with confidence.
The problem is that graphene is ten times more expensive than gold and the application cost is too high. The graphene production technology developed by Liu Zhaoping and his team reduced the value of graphene 5,000 yuan per gram to 3 yuan per gram.
Yesterday morning, at the awarding ceremony of the “2011 China Science and Technology Entrepreneurship Competition†held in Ningbo, Liu Zhaoping won the “Overseas Talent Entrepreneurship Award†with the highest amount of 1 million yuan.
Let the world's thinnest material price drop from 5,000 yuan per gram to 3 yuan per gram
Liu Zhaoping explained that graphene is a two-dimensional crystal composed of carbon atoms which is peeled off from graphite materials. It was discovered in 2004 and is the thinnest material found in the world. In 2010, the graphene discoverers won the Nobel Prize in Physics.
Liu Zhaoping said that the graphene-powered lithium battery made of graphene has higher conductivity and lower resistance in the battery. The storage capacity and fast charge and discharge capacity are much stronger than ordinary lithium batteries. Not only that, graphene is extremely soft, and it is added to the production to create the display in the movie "Avatar": transparent, can be bent at will, thin as paper.
However, the cost of preparing graphene is too high, and the price reaches 5,000 yuan per gram, which is more than ten times that of gold, which greatly limits the application of graphene.
Liu Zhaoping calculated that his graphene industrialization technology, once put into production, the price of graphene can be reduced to 3,000 yuan per kilogram, which is 3 yuan per gram.
Liu Zhaoping said that in July this year, his research and development team has cooperated with a Ningbo company to build the world's first production line with an annual output of 30 tons of graphene, and has already received some orders.
Liu Zhaoping is 35 years old. He is from Xingguo, Jiangxi. He graduated from the State University of New York and has participated in research work in many new materials research institutions such as Japan and New York. In October 2008, after graduating from a postdoc, he applied to work at the New Energy Technology Institute of Ningbo Materials. After only 3 years, he and his team solved the problem of large-scale preparation of graphene.
