Information
While the entire province is learning and implementing the spirit of the important speech of the Heilongjiang delegation during the National Conference of General Secretary Xi Jinping, this newspaper launched a series of planning reports on “Dragging and Rejuvenating the Longjiang” to show the general secretary of each province in various industries and departments. The requirement of “promoting weaknesses, avoiding weaknesses, shortening weaknesses, and strengthening weaknesses” was put forward. Focusing on the center of economic construction, we focused on the dedication and dedication, and worked hard to get out of the new path of revitalizing Longjiang.
A piece of graphite placed on the bookshelf of Zhang Haijiae, vice president of the Provincial Institute of Graphite New Materials Engineering, is the same size as a fist. Its appearance is the same as that of a coal block. There is no diamond or gold dazzling, but Zhang Haijiao told reporters that like rare earth, Graphite and new materials that have been stripped from graphite have become "stars" in the fields of energy and new materials. As the main producing area, our province has sufficient graphite raw materials and strong scientific research strength. The enterprises and universities are jointly working on new graphene materials, and the Longjiang graphite industry has been gradually upgraded. It has been transformed from the original raw material export province into a high-tech research and development center, combined with application promotion, graphite change. Become "black gold."
Charging 6 minutes to run 300 km "super battery" will be produced in Kazakhstan to produce ultra-thin graphite paper only 30 micron made heat sink sell well
Have you seen batteries that can be used below -55C? Have you seen an electric car that can be fully charged and travel 200 to 300 kilometers in 6 minutes? All these will become reality in the ice city.
The "super battery" that created the "miracle" was not a previous nickel-cadmium battery, nor was it a lithium battery, but was made of graphene, a new material. The cruising range is at least 10 times higher than that of lithium batteries. This is the graphite frontier technology project of Beijing Zhongbo Xinyuan Company officially settled in Harbin at the beginning of the month.
Earlier this year, the battery produced by powdered graphene from the Huasheng Industrial Company of Heilongjiang Province had the same battery life as the Cambridge University of the United Kingdom. A single charge enabled the electric vehicle to travel about 650 kilometers.
Yang Yusheng, general manager of Harbin Tianbao Graphite Co., Ltd., said that graphite has become a “star” in new energy and new materials. They and the Harbin Engineering University have jointly established the Collaborative Innovation Center for Graphite New Materials to make graphite into 30 micron thick graphite paper. The production of LED heat sinks, only this product, brought a large number of orders to the company.
It is not a simple matter to peel off graphene from graphite. However, Harbin Fuller Technology Development Co., Ltd. and Heilongjiang University of Science and Technology jointly joined hands to create an independent brand—graphene intercalation and stripping method. It can successfully strip 1 to 10 layers of graphene and achieve layered control below 10 nm. , to achieve the leading domestic level.
Academician Peking University came to Harbin Lab to develop graphene wearable devices
In the Wanxin Graphite Valley Technology Co., Ltd. in Songbei District, a brand of “PKU-Baoan Carbon Technology Laboratory” is very eye-catching. This is a scientific research team of Academician Liu Zhongfan of Peking University. He cooperated with the company on the key technology of graphene application and will apply graphene to wearable devices to promote the industrial application of graphene.
Qitaihe Baotailong Coal Company, which is engaged in the traditional coal chemical industry, entered the graphene field in 2015. According to the announcement, the company has signed a cooperation agreement with the Institute of Nuclear Energy and New Energy Technology of Tsinghua University. It will use graphene to stretch 20% without breaking, making it a display device that can be folded and stretched.
As early as 2012, Aoyu Group of Heilongjiang University and Academician Yu Yongfu of Wuhan University of Technology established the “Workstation of Academician of High Thermal Conductivity Graphite Materials”, which is the first and only academician workstation for the graphite industry in China.
There is raw material technology
Several graphite high-tech companies settled in our province
In our province, scaly graphite has been identified at 1.04 billion tons, accounting for more than 64% of the country’s total reserves of minerals.
Zhang Haijiao told reporters that Harbin Institute of Technology, Harbin Engineering University, Harbin University of Science and Technology, Heilongjiang University, and Heilongjiang University of Science and Technology have made breakthroughs in graphite new energy materials, power batteries, high-grade sealing materials, and aerospace materials.
In addition to these colleges and universities, our province has also established the old electric carbon graphite company Harbin Electric Carbon Plant in 1956. The plant is a designated unit for the design and production of graphite materials for the aerospace industry in the country, with core graphite technology.
There are raw materials, there are technologies, attracting a large number of well-known graphite high-tech companies to invest in our province settled down. The reporter learned from the Provincial Graphite Industry Association that there are more than 50 original graphite companies in the province, plus more than 60 homes of Wanxin and the recent Nangang Graphite Industrial Park.
At the same time, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the National Certification and Accreditation Regulatory Commission formally issued a document on March 14. The National Quality Supervision and Inspection Center for Graphite Products officially landed in Jixi, filling the gap in the supervision and inspection of integrated graphite products in the north of the Yangtze River.
