Longli Biographene helps the new energy vehicle industry enter an accelerated adjustment period

Recently, the National Development and Reform Commission announced that all foreign equity restrictions in the automobile industry will be lifted in the next five years. At the same time, as subsidies for new energy vehicles continue to decline, new energy vehicles have entered a period of accelerated adjustment of the industry.

New energy vehicles are a new development trend in the automotive industry, but the shortcomings of automotive power batteries, such as limited driving range and long charging time, have hindered the popularization of electric vehicles. Graphene material is the thinnest, lightest and strongest new nanomaterial discovered in the world. It has excellent electrochemical energy storage characteristics, ultra-fast charging and discharging, and cyclic charging, which can bring disruptive changes to automotive power batteries. At present, the Ningbo Institute of Materials, Chinese Academy of Sciences has developed a graphene-modified high-energy-density lithium-ion supercapacitor, and has passed the new product appraisal organized by the Ningbo Economic and Information Commission. Experts believe that the product has a single-cell capacity of 17KF, an energy density of more than 20Wh/kg, and a power density of nearly 8kW/kg, and the technical level has reached the international leading level. This type of product has received good feedback from users, and its main technical performance meets the requirements of use. At the same time, it also has the ability to be put on the market in batches. This will solve the important obstacles to the development of new energy vehicles and drive the industry to achieve rapid development.

According to the forecast of the Industrial Research Center of China Graphene Industry Technology Innovation Strategic Alliance, the global graphene application market will grow to 100 billion yuan in 2020, and China will occupy a dominant position in the global graphene market.

Shandong Longli Biotechnology Co., Ltd. is a biomass comprehensive utilization enterprise that produces bio-based graphene by using corn cob waste residue after producing functional sugars, cellulosic ethanol and lignin. The products are widely used in traditional and emerging fields such as chemical coatings industry, composite materials industry, semiconductor industry, photovoltaic industry, lithium-ion batteries, new generation display technology, aerospace, military industry, etc., with the characteristics of abundant raw materials, low production cost, no pollution to the environment and high added value.

In May 2017, Longli Bio's joint-stock company Longju New Materials successfully completed the equipment installation, commissioning and production of the graphene pilot production line. After purification and inspection by the Ningbo Institute of Materials, Chinese Academy of Sciences, the graphene products prepared by Longju New Materials are less than 10 layers, and the yield continues to improve. The fine graphene products purified by Longju New Materials have been introduced to related customers such as rubber, tires, thermal conductive films and anti-corrosion coatings for trial use.

It is reported that the "300 tons of bio-based graphene industrialization construction project per year" of Shandong Longju New Materials Technology Co., Ltd., in which Longli Biotechnology holds a stake, has been included in the Shandong Province's old and new kinetic energy conversion project library. The project uses cellulose ethanol or lignin extracted from corn cob waste as raw materials to prepare bio-based graphene at low cost. It is the first to use cellulose and lignin from plant straw as biological sources for graphene preparation, and obtain high-quality graphene through simple processes. After the project is completed, it will form a scale of 300 tons of bio-based graphene per year.

With the continuous innovation of graphene technology, Longli Bio's graphene industry will make efforts to help the new energy vehicle industry transform its old and new kinetic energy.
