Enter Amp New Energy Technology Co., Ltd. | Experience the practical application of "protecting the blue sky with fluorine chemistry"
Enter Amp New Energy Technology Co., Ltd. | Experience the practical application of "protecting the blue sky with fluorine chemistry"
Global warming, depletion and destruction of the ozone layer, reduction of biodiversity...With the pace of human development, global environmental issues are becoming increasingly severe, and environmental protection has become a common topic for the international community.With the proposal of the "dual carbon" target, promoting the green and low-carbon transformation of the economy and society has become a major systemic project, and enterprises will undoubtedly become the vanguard of global environmental governance. Adhering to the concept of "science first", Amp New Energy Technology Co., Ltd. has undertaken the construction of national key laboratories for fluorine greenhouse gas substitution and control treatment, as well as the national ODS substitute engineering technology research center and other national level innovation platforms.They have developed a new generation of green refrigerants, foaming agents, and other products, with the annual elimination of ODS accounting for about 10% globally and contributing to a reduction of 460 million tons of CO2 equivalent, equivalent to the average annual absorption of CO2 by 40 billion trees. This is the low-carbon vision that China Blue Sky is painting. On World Environment Day on June 5th, at the media open day event held by China Blue Sky, we understood the original intention of a fluorine chemical enterprise to "protect the blue sky" for 72 years and the beautiful belief of promoting world high-quality development through technological innovation. Amp New Energy Technology Co., Ltd. is truly a "sky protector".As early as 1999, the Zhejiang Chemical Research Institute under Amp New Energy Technology Co., Ltd. was approved to establish the only "National ODS Substitute Engineering Technology Research Center" in China, being the first research institution in the country to engage in ODS replacement research. Today, the center has developed a large number of influential ODS substitute varieties and technologies, winning awards such as the "Ozone Layer Protection Contribution Award" from the National Environmental Protection Bureau, making significant contributions to China's compliance with the Montreal Protocol and product upgrades. Currently, the national key laboratory for fluorine greenhouse gas substitution and control treatment has achieved a series of innovative results in the development of fluorine greenhouse gas substitutes, green process development, and fluorine gas capture and conversion, providing strong technical support for reducing emissions at the source, process control, and end-of-pipe treatment of fluorine greenhouse gases. During the open day, journalists experienced a magical "water" where a tablet computer could function normally when submerged in it, and a light bulb could be powered on safely when placed in it. Researcher Wang Fei explained that this was the "miraculous fire extinguishing agent" called perfluorohexanone, developed by the company's national key laboratory. This fire extinguishing agent has excellent insulation, compatibility, and efficiency, but most notably, its environmental friendliness. Perfluorohexanone is currently one of the ideal replacements for halon, with an ODP value of 0 and a GWP value of only 1, compared to the GWP value of 3500 for the currently used fire extinguishing agent, heptafluoropropane. This means that for the same fire extinguishing effect, the greenhouse gas emissions released into the atmosphere are only 1/3500 of the original amount! With an atmospheric residence time of 5 days, it is truly a green and environmentally friendly fire extinguishing agent.

New energy vehicles with a range of 700 kilometers? Can't do without this material!
New energy vehicles with a range of 700 kilometers? Can't do without this material!
At the beginning of the 20th century, the range of new energy vehicles was only 40 kilometers. Today, many new energy vehicles can travel over 700 kilometers on a single charge, thanks to the revolution in battery technology, which has driven rapid industrial development. Today, we will decrypt the "code" behind the range of new energy vehicles and understand the core functional material behind it, PVDF lithium battery binder.Decrypting the low-key hero in lithium batteries - lithium battery binder The lithium battery we are familiar with mainly consists of electrodes (positive and negative electrodes), electrolytes, and separators. During the charging and discharging process of the battery, lithium ions (Li+) are repeatedly inserted and extracted between the positive and negative electrodes, while electrons form a current through an external circuit.Where is the lithium battery binder? ☟ The lithium battery binder is "stuck" on the positive electrode sheet ☟Why is a binder needed? This is because the electrode is composed of a metal electrode sheet and electrode material attached to it, and there is no adhesive force inside the electrode material or between the electrode material and the metal electrode sheet. The binder is needed for "bonding" to maintain the integrity of the electrode structure. How important is the lithium battery binder? The lithium battery binder is an indispensable component in lithium batteries. Although it accounts for a small proportion, it is the main source of the overall mechanical performance of the electrode, and it has a significant impact on the production process of the electrode and the electrochemical performance of the battery.The main functions of lithium battery binders: ▶▶ Bonding active materials, conductive agents, and current collectors to maintain electrode structure integrity ▶▶ Acting as a dispersant or thickener to improve the uniformity of electrode components In summary, lithium battery binders, which account for only about 1% of the total cost of lithium batteries, play a significant role in the core performance of batteries such as cycle life, charge-discharge capacity, rate capability, and so on.Why choose PVDF as the lithium battery binder? Lithium battery binders not only carry so many responsibilities, but also need to work stably in extremely harsh environments for a long time. In daily life, the adhesives we use are mostly hydrocarbon polymers, which have the advantages of low cost, quick drying, and strong bonding strength. For example, pressure-sensitive adhesive (acrylic resin) and super glue (alpha-cyanoacrylate) are commonly used. However, the internal environment of lithium batteries is harsh. The binders and electrode materials are constantly immersed in the electrolyte, subjected to various electrochemical reactions, and required to maintain long-term stability within the working voltage range of the electrodes. Ordinary hydrocarbon "glues" are either dissolved in the electrolyte or oxidized by the electrochemical environment. The task of bonding lithium batteries is not something that general adhesives can handle. This is where PVDF comes in. PVDF (polyvinylidene fluoride) is a special fluorinated olefin polymer. Compared to the "king" of olefin polymers polyethylene, half of the hydrogen atoms in PVDF are replaced by fluorine atoms, forming carbon-fluorine bonds instead of carbon-hydrogen bonds in polyethylene. These bonds have a high energy, are very strong and difficult to break, making PVDF much more stable than general hydrocarbon polymers. In addition, because fluorine atoms have strong electronegativity, PVDF is highly polar and can dissolve in some strong polar solvents such as amides, forming a flow system of electrode materials, binders, and solvents for coating on electrode sheets. Witness the Four Winning Moves of PVDF #"Stable" PVDF has good chemical stability, is acid-resistant and oxidation-reduction-resistant, will not be dissolved by the electrolyte, will not be oxidized under high voltage conditions, and will not react or deteriorate during storage and cycling. #"Bonding" If the bonding strength of the binder is insufficient, the electrode material may detach from the electrode sheet after multiple charge-discharge cycles, rendering the battery unable to store energy and leading to the entire battery being scrapped. Compared to tetrafluorine binders, PVDF has both carbon-fluorine bonds and carbon-hydrogen bonds, forming hydrogen bonds with the oxygen elements on the positive electrode to firmly adhere the positive electrode particles. #"Flexible" PVDF has enough flexibility to ensure that the active materials do not detach during repeated expansion and contraction, and the binding between electrode particles is not destroyed. #"Dissolve" PVDF lithium battery binders have good solubility, fast dissolution speed, and high solubility. After PVDF is dissolved into a solution, it can be evenly dispersed into the positive electrode material and the surface of the electrode sheet, effectively bonding the active materials uniformly to the current collector.Amp New Energy Technology Co., Ltd. What's the big difference in PVDF lithium battery binderInnovation-driven, high-end products achieve domestic substitution Amp New Energy Technology Co., Ltd. has been deeply involved in fluorine chemical industry for more than 70 years, with more than 40 years of deep accumulation in the field of PVDF research and production technology, and has presided over and participated in many scientific and technological research projects. Since 2009, Amp New Energy Technology Co., Ltd. has started to develop PVDF products specifically for lithium battery binders, successively developing 5 grades of PVDF products including emulsion, suspension, and modified types, and has accumulated a number of leading technologies and "Know-How" in VDF monomer synthesis, PVDF polymerization process formulation, and resin scale production. It has many "unique skills" in areas such as fluoropolymer quasi-steady-state polymerization, constant ratio copolymer modification, and condensed phase structure analysis. Innovative mechanism, efficient operation of "research, production, sales, and inspection"Amp New Energy Technology Co., Ltd. has a complete set of small-scale, medium-scale, and industrialization supporting facilities, and integrates product development, performance evaluation, application research, production, and sales in one. The project team focuses on product design and process manufacturing, with customer application requirements as the guide, and creates sustainable innovation capabilities. At the beginning of 2021, the domestic new energy electric vehicle industry ushered in an explosive growth market situation, and the demand for PVDF from lithium battery manufacturers quickly increased. The project team took rapid action, conducted targeted product small-scale experiments to prepare samples, and achieved the formalization of a new green and high-performance emulsion method PVDF grade in just 3 months; and overcame the scalability issues of synthetic process amplification. While optimizing experiments and saving production costs, the new product was efficiently scaled up for production, successfully integrating the product into the supply chain system of leading enterprises in the lithium battery industry. At the same time, Amp New Energy Technology Co., Ltd. is also one of the few PVDF manufacturers in China that provide evaluation laboratories for lithium battery applications. The application evaluation laboratory has the ability to evaluate most of the downstream lithium battery customer trial lines, test indicators such as solid content, stability, rheological properties of lithium battery slurry containing PVDF, and coat them into electrode sheets to evaluate the relevant performance of the electrode sheets. It is equivalent to moving some of the evaluation capabilities of lithium battery customers into the laboratory, greatly reducing the distance between products and applications, and achieving efficient connection with the market.

Cutting-edge technology in new energy vehicles: Conductive carbon black
Cutting-edge technology in new energy vehicles: Conductive carbon black
Conductive carbon black is a type of conductive agent and an important auxiliary material in lithium batteries.Compared to other conductive agents, conductive carbon black has better overall performance and is currently the mainstream conductive agent. Benefiting from the continuous growth in demand for downstream new energy vehicles, we expect the global market space for conductive carbon black to be around 7.6 billion yuan by 2027. In terms of production process, the main barrier for conductive carbon black lies in the design of reaction furnace equipment. In terms of production cost, the main cost components of this product include raw materials such as coal tar. In terms of market landscape, this product has mainly relied on imports in the past, but is currently accelerating domestic substitution. Domestic companies mainly include Black Cat Corporation, Jiaozuo Hexiong, Yongdong Corporation, and Wuxi Dongheng. Looking at future trends, conductive carbon black is suitable for the trend of composite conductive agents. Conductive carbon black is the mainstream lithium battery conductive agent, with core technology creating barriers Conductive agents are important auxiliary materials for improving the conductivity of lithium batteries, which can compensate for the poor conductivity of positive electrode materials and maintain the conductivity performance of negative electrode materials after repeated expansion and contraction. Conductive carbon black performs well when considering factors such as the degree of improvement in electrode conductivity, slurry dispersion performance, formulation dosage, and cost. According to GGII data, conductive carbon black accounted for 65% of China's power battery conductive agents in 2022. The performance of conductive carbon black is mainly determined by its structural characteristics, specific surface area, and magnetic impurity content. The performance requirements for lithium-grade conductive carbon black are higher than for ordinary carbon black, and the product performance can be classified from low to high as acetylene black, SP, and Ketjen black. The reaction furnace is an important reaction equipment and a core barrier for the production of conductive carbon black, with components such as the oil nozzle in the furnace head being crucial for accuracy. Localization and cost reduction are the trend, with potential for small and beautiful new energy tracks In terms of cost composition, raw materials such as coal tar account for approximately 80% of the cost of conductive carbon black. The price of imported conductive carbon black has long been high, with shipping costs accounting for a certain proportion.Domestic substitution can eliminate shipping costs, while domestic raw material costs are lower than overseas costs, making it cost-effective. Assuming that the proportions of conductive carbon black added to ternary positive electrode materials, lithium iron phosphate and other positive electrode materials, and negative electrode materials are 2%, 3%, and 1% respectively, and the penetration rates of conductive carbon black from 2023 to 2027 are 56%, 54%, 52%, 51%, and 50%, the global market demand for conductive carbon black from 2023 to 2027 is estimated to be 48,000 tons, 66,000 tons, 89,000 tons, 118,000 tons, and 152,000 tons, corresponding to market spaces of 3.14 billion yuan, 3.94 billion yuan, 4.87 billion yuan, 6.15 billion yuan, and 7.60 billion yuan. Domestic substitution is underway, with efforts to promote expansion In the past, due to the dispersed scale of domestic carbon black companies and their focus on the tire market, as well as insufficient core research and development technology for reaction furnaces, domestic conductive carbon black was almost entirely dependent on imports. Major companies included France's Orion Stone, the United States' Cabot Corporation, Japan's Lion King, and Japan's Denka Corporation. With the accelerated penetration of downstream new energy vehicles and the significant increase in demand for lithium batteries, overseas supply of conductive carbon black has been unable to meet demand and prices have been high. Domestic companies have begun to initiate domestic production, gradually achieving technological breakthroughs. Major companies include Black Cat Corporation, Jiaozuo Hexiong, Yongdong Corporation, and Wuxi Dongheng.Risk warning: Lower-than-expected sales of downstream new energy vehicles, slower-than-expected industrialization progress, technological innovations, and the mention of companies in the industry chain do not represent coverage or investment recommendations for the company.
