Graphene-based lithium battery announced Dongxu Optoelectronics launches new engine

On September 10, Dongxu Optoelectronics and Shanghai Carbon Source Huigu, a holding subsidiary, launched the latest graphene-based forklift lithium-ion battery successfully developed and commercialized. In the view of Dongxu Optoelectronics, the launch of this new product not only marks the company's graphene-based lithium-ion battery technology to make the leap from miniaturized fast-charge batteries to large-power lithium batteries, but also successfully launches Dongxu Optoelectronics graphene business for the second time. The new engine taking off. Different lithium-ion batteries According to the information disclosed by Dongxu Optoelectronics, the cycle life of this product can reach 5000 times evenly under 5C charge and discharge conditions, which can meet the normal working temperature between -20℃ and +60℃, and the charging and discharging efficiencyu0026ge; 98%. Different from conventional power lithium-ion batteries, this product of Carbon Source Huigu is a graphene-based lithium-ion battery for the electric forklift market. According to Guo Shouwu, a professor and doctoral supervisor of the School of Electronic Information and Electrical Engineering of Shanghai Jiaotong University, the breakthrough point of the graphene industry is to develop products that are truly market-oriented. There is one thing that is not considered comprehensively, and it is not a product. In fact, before the launch of the new product, the carbon source sinking research team was dormant for a year to in-depth research on the pain points of the forklift market, and targeted improvements to the product. First of all, although the essence of the lithium-ion battery in the forklift and the new energy vehicle category is the same, the technical performance indicators are completely different. The usage scenarios of forklifts determine its characteristics such as frequent start and stop, high peak current, and harsh working conditions. It puts forward requirements for low voltage, high current, stacking, counterweight and other requirements for the adapted power lithium-ion battery. The existing new energy vehicle lithium Ion batteries cannot be adapted. Secondly, the graphene-based lithium-ion battery launched by Carbon Source Huigu uses graphene-coated lithium iron phosphate as the cathode material. According to Professor Guo Shouwu's analysis, graphene-coated cathode material reduces the resistivity except the internal resistance of the material itself, and enhances conductivity, making graphene-based lithium-ion batteries have fast charging and ultra-long cycles compared with conventional lithium-ion batteries. Life and other characteristics. Dong Xinhua, CTO of Carbon Source Sinusica, said: Our batteries can be fully charged in an hour, while lead-acid takes 8 hours or more. Forklift lithium-ion batteries are a new blue ocean in the lithium battery industry. According to market research data from Dongxu Optoelectronics and intermediary agencies, the sales of electric forklifts in my country will reach 300,000 units in 2021, of which 100,000 units will use lithium-ion batteries. By then, the demand for lithium-ion batteries in new forklift trucks and the aftermarket will reach 210,000 yuan, the market size is around 5 billion yuan. Forklift trucks have high requirements for instantaneous current, and vehicle body vibration can cause great damage to the battery. This is not a low threshold. Professor Guo Shouwu said in an interview with Shanghai Securities News. Activating the new engine of Dongxu Optoelectronics In the opinion of Dongxu Optoelectronics chairman Wang Lipeng, the announcement of the graphene-based forklift lithium-ion battery is the starting point for the second take-off of Dongxu Optoelectronics graphene business. Dongxu Optoelectronics has not changed the direction of graphene as an important development strategy of the company, and it continues to increase its strength. Dongxu Optoelectronics adheres to the development plan of small steps and fast running in the graphene-based lithium-ion battery business. Dr. Feng Weidong, Vice President of Dongxu Optoelectronics and Chairman of Carbon Source Huigu, analyzed: The first step is to develop high-quality (graphene-based) cathode materials; the second step is to perform technical verification and use on 3C and small power tools The current launch of forklift batteries and commercialization on industrial vehicles is the third step; the ultimate goal is to be widely used in commercial vehicles, AGVs, robots and other fields. It is worth noting that Tunghsu Optoelectronics is combining its own industrial advantages to accelerate the construction of an industrial closed loop from the preparation of graphene materials to graphene-based lithium-ion battery new energy vehicles. In addition to the closed-loop industry, Tunghsu Optoelectronics will enhance the research and development of graphene products in an endogenous and epitaxial manner, combining the existing advantages of high-tech intelligent manufacturing and integrated marketing to promote the formation of industrial synergy between the graphene business and other businesses. Dongxu Optoelectronics has clarified the realization path of the high value-added industrial use and development of electric lamp heating cores. The electric lamp thermal cores correspond to the four important products of graphene-based lithium-ion batteries, graphene energy-saving lighting, graphene thermal management, and suspended graphene sensor chips. The suspended graphene sensor chip is a collaboration between Dongxu Optoelectronics and the University of Manchester. New crystals. Industry-university-research is becoming the moat of Dongxu Optoelectronics in the field of graphene. Wang Lipeng said that the company and Mandazheng discussed the establishment of a joint venture company in my country. The establishment of a joint venture company in China will help accelerate the industrialization of front-end scientific research results, and there should be results within the year (joint venture matters). In addition to Manchester University and Shanghai Jiaotong University, Dongxu Optoelectronics has also reached cooperation in the field of graphene with Jiangxi University of Science and Technology, Zhejiang University, and Beijing Institute of Technology. Dongxu Optoelectronics also set its sights on the Sci-tech Innovation Board. The state encourages the development of science and technology innovation, and we are also actively studying the policies of the science innovation board and making full use of the policies. When talking about the Science and Technology Innovation Board, Wang Lipeng said that this is also the philosophy of 'Serving the country with industry and making the country strong with science and technology' that Dongxu people have upheld for many years.
