Lead a new era of new energy batteries! DFD third generation large cylinder “fluorine core battery” is available
Recently, Polyfluoro (002407), a leader in the fluorine material industry, officially announced that its self-developed third-generation large cylinder battery – “fluorine core battery” was officially launched, marking the company has made another major breakthrough in the field of new energy batteries. This release not only highlights the strong technical strength and market foresight of polyfluoro, but also injected strong impetus into the development of China’s new energy automobile industry.
As an important achievement of the multi-fluoride new energy strategy, the fluorine core battery integrates the company’s latest research results on the three core elements of battery safety, capacity and cost. Through the introduction of innovative technologies such as bidirectional pressure relief explosion-proof valves, unique formula additives and single-side bus design, comprehensive upgrades are achieved in terms of energy density, safety, service life and cost control.
In terms of safety technology innovation, the bidirectional pressure relief explosion-proof valve independently developed by DFD has become a highlight of the industry. Compared with the traditional one-way pressure relief valve, the bidirectional pressure relief explosion-proof valve has higher flexibility and adaptability. It can open different pressure relief valves according to the different internal pressure of the battery to release the pressure in time to balance the internal and external pressure difference and achieve double protection. This bi-directional adjustment enables the battery to maintain stable performance and safety even under the most severe abuse conditions.
In the battery formula, through the introduction of anionic unsaturated additives, new fluorine-containing electrolyte flame retardant additives and negative fast ion conductor additives, fluorine core batteries have successfully achieved synchronous improvement of energy density, safety and service life. These additives not only optimize the crystal structure and electrical conductivity of the battery material, but also significantly enhance the self-protection ability of the battery under extreme conditions.
In the battery material, the anionic unsaturated additive interacts chemically with the active substance in the battery, thereby increasing the energy density of the material. At the same time, it can also improve the conductivity and ion mobility of the battery, reduce the internal resistance of the battery, and further improve the output power and cycle stability of the battery.
A new flame retardant additive containing fluorine functional group was introduced into the battery electrolyte. It can respond quickly when the thermal runaway occurs inside the battery, effectively capture the hydrogen and oxygen free radicals generated in the thermal runaway, so as to effectively inhibit the spread of the flame and the sharp rise in temperature, greatly reducing the risk of fire and explosion of the battery. In addition, the additive can also work synergistically with other components in the electrolyte to improve the overall electrochemical performance of the battery and extend the service life of the battery.
In the negative electrode material of the battery, the carefully designed negative fast ion conductor additive can promote the rapid migration and diffusion of lithium ions at low temperatures. By optimizing the microstructure and conductive network of the anode material, the anode fast ion conductor additive significantly improves the charge and discharge efficiency of the battery at low temperature, thereby effectively alleviating the capacity attenuation problem caused by low temperature.
Although the traditional two-side bus design in battery production is mature, it has certain limitations in cost and efficiency. The innovative use of single-side junction design not only reduces the production cost of the battery, but also optimizes the spatial layout of the battery pack, improves the simplicity of the module structure and assembly efficiency, and makes the battery reach a new height in terms of cost control and performance optimization.
In the battery production process, DFD always adhere to the principle of quality first. The company deeply integrates the concept of intelligent manufacturing into the production process, and realizes the precise control and efficient operation of the production process through automation, digitalization and intelligent means.
In order to ensure the impeccable quality of the battery, the company adopts advanced and comprehensive testing technology, covering every production link from raw materials to finished products, to ensure that every battery can withstand stringent quality tests.
Through intelligent manufacturing and testing system, polyfluoride has formed a set of scientific and strict quality control system, covering all aspects of the production process, this comprehensive and multi-level quality control ensures the continuous optimization and improvement of battery quality.
At present, DFD has a production capacity of 8.5GWh, which can fully meet the market demand for high-quality and high-performance power batteries.
In the process of expanding to the light vehicle market, the company takes the technology of automotive grade lithium-ion power battery as the entry point, and successfully develops a full series of 12-100AH capacity single battery, which can meet all the needs of the two – and three-wheeled electric vehicle market, not only enriching the product line, but also further enhancing the brand influence of the company in the field of new energy.
In the future, with the continuous progress of technology and the continuous expansion of the market, DFD will achieve more brilliant achievements in the field of new energy batteries. The company firmly believes that the release of fluorine core batteries will open a new chapter in the new energy battery industry, and will lead the industry to a more safe, efficient and sustainable direction.
