Dongxu Group builds two graphene-based lithium battery production lines

After the bio-based environmental protection new materials, Man Wei 4.0 and Huanlv New Energy Vehicle Project settled in the new energy industrial park, another high-tech leading project will also take root here. On July 8, good news arrived from the Diaoyutai state guesthouse in Beijing. Dongxu Group officially “married” with the city and will invest 500 million Yuan to build two graphene-based lithium battery production lines in the new energy industrial park. After the project is put into production, it is estimated that the annual sales will exceed 1 billion Yuan.

According to reports, Dongxu Group was established in 1997. It is a multi-industry investment group that integrates financial and urban real estate with the core of photoelectric display and new energy as its core. It owns two listed companies, Dongxu Optoelectronics and Baoan Real Estate two listed companies and more than 40 wholly-owned and holding subsidiaries. Dongxu Optoelectronics Co., Ltd. is the core supplier of the key supporting materials for the upstream localization of flat panel display in China's optoelectronic display field. It ranks first among the A-share companies in the Forbes 2014 China Top 100 Listed Companies.

"In line with the development trend of the new materials industry, Dongxu Optoelectronics has listed the graphene industry as an important pole in the company's future industrial development strategy, actively expanding the industrial application of graphene in optoelectronic display, new energy and other fields, and accelerating graphite. The layout of the olefinic industrial chain," said Wang Zhonghui, head of Dongxu Optoelectronics Investment.

Wang Zhonghui introduced the graphite alkenyl lithium battery project that was settled in the new energy industry park. The investment entity is Shanghai Carbon Source Huigu New Material Technology Co., Ltd., which is controlled by Dongxu Optoelectronics. The company is the only company in China that can achieve high-quality single-layer graphene scale production (up to ton per year). It is in the industry in the preparation, separation and purification technologies and processes of single-layer graphene oxide and grapheme forefront. The total investment of the project is 500 million Yuan, with a total area of 170mu, which will be constructed in two phases. The first phase will build a production line with an annual output of 3 tons of low-cost high-quality single-layer graphene, one production line of 300 tons of lithium battery positive/negative materials, and the second phase of construction of 150 million Wh of power battery cells and pack production plants. After the project is put into production, it is estimated that the annual sales will exceed 1 billion Yuan.

“The new energy industrial park with the lithium battery industry chain as the key point and characteristics will form a strong downstream support for the development of graphene industry. This is one of the important reasons for Dongxu to choose a new energy industrial park.” Hailing District Committee Chen Xiang, deputy secretary and head of the district, said that the new energy industry park is currently using the automotive power battery, high-power energy storage battery , new energy equipment R & D and manufacturing as a breakthrough, with energy-saving emission reduction, new energy technology in urban construction and other fields of demonstration applications. Based on promotion, we will focus on building four industrial clusters of photovoltaic, energy storage new energy equipment manufacturing and energy conservation and emission reduction. “Graphene is known as the king of materials in the 21st century. After the Dongxu photoelectric graphene-based lithium battery project is settled in the new energy industrial park, it will have a huge demonstration effect, attracting more new materials and new energy projects to settle in Hailing and even Taizhou. Efforts will be made to create a complete graphene industrial chain that integrates scientific research and innovation and incubation."

"We first met Dongxu in Kunshan two years ago, because Dongxu Optoelectronics mainly worked on supporting LCD panels, and the New Energy Industrial Park lacked the conditions for its support, and missed the opportunity to become a first time." Fei Wu, deputy secretary of the Party Committee of the Energy Industry Park, said that after the first "lost love", the park deeply realized that it is necessary to improve the industrial carrying capacity of the park, in order to enhance the attractiveness of the park and enhance the success rate of investment, in order to change the impossible. It is possible.

It is reported that after learning about the industrialization of Dongxu photoelectric graphene, the new energy industry park carries forward the spirit of "three do not believe" and persists in keeping a close eye on it. After repeated docking and negotiation, in March this year, Dongxu Optoelectronics and the New Energy Industrial Park jointly set up a 100 million graphene industry development guidance fund, based on the integration of Dongxu Optoelectronics' existing industrial resources and technical strength.

Fei Wu said that the development guide fund will be used to throw out the olive branch and then use specific projects to cash in. The purpose is to attract more projects to settle down through cooperation between the two parties, actively build a graphene industrial cluster, and promote new energy industry parks to file. Upgrade, leapfrog development.

What is a graphene-based lithium battery?

Graphene battery is a new energy battery developed by taking advantage of the rapid and large amount of shuttling between the graphene surface and the electrode of lithium ions. It has the characteristics of quick charge and quick release, and has a huge market prospect in consumer electronics, power battery and energy storage. The core feature of graphene-based lithium batteries is that they can be filled or emptied in 6 minutes. In addition, the product has excellent cycle performance and high and low temperature properties. Graphene-based lithium batteries can significantly shorten the battery charge and discharge time, extend battery life and increase battery capacity, which can greatly enhance the endurance of new energy vehicles and promote the popularity of new energy vehicles.
