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.

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.
