Lithium-ion Battery Slurry Mixing Equipment Mar 19, 2024
Lithium-ion Battery Slurry Mixing Equipment
Double planetary mixer Currently, the mainstream slurry mixing equipment used by lithium-ion battery manufacturers is the double planetary mixer, also known as the PD mixer. This mixer is equipped with a low-speed mixing component, Planet, and a high-speed dispersing component, Disper. The low-speed mixing component comprises two folding frame agitators that utilize planetary gear transmission. As the agitators rotate and orbit, they allow the material to move in various directions, achieving the desired mixing effect within a relatively short time. The high-speed dispersing component typically features a toothed dispersing disk that rotates along with the planetary carrier while spinning rapidly, exerting intense shearing and dispersing forces on the material. This effect is several times greater than that of ordinary mixers. Additionally, the dispersing component can be configured with either a single or double dispersing shaft, depending on the specific requirements of the application. Ball mill mixing Ball milling mixing is also often used for the preparation of lithium-ion battery slurry, which is generally more common in laboratories. Similar to fluid mechanics-based mixing methods, the dispersion ability of the ball milling process is determined by the balance of cluster fragmentation and agglomeration reorganization speeds, which is related to the properties of powder particles and can be changed by the addition of surfactants. In the ball milling process, powder particles undergo a large number of surface and volumetric changes, which may lead to mechanical and chemical transformations of the material (such as the rupture of carbon nanotubes, changes in their aspect ratio and structure). Reactions may occur between particles, between powder and dispersing media (solvents and binders), and even between powder and grinding balls. Collisions between grinding balls and local fluid high-shear turbulence can also cause the rupture of binder molecules. Ultrasonic stirring Currently, ultrasound is used by people for mixing at the microscopic scale based on the transient acoustic cavitation effect. This effect needs to be generated under quite high ultrasonic intensity, accompanied by the formation and growth of a large number of microbubbles. When the bubble size reaches a certain critical value, the bubble growth rate increases rapidly and then ruptures instantly, forming shock waves to disperse agglomerates while causing local high temperature and high pressure (local pressure can reach thousands of atmospheres). Another process that occurs during ultrasonic mixing is the macroscopic flow of the liquid. The concentration of cavitation bubbles gradually decreases along the axis centered on the generator, and the bubbles diffuse to low-concentration regions, driving the liquid to flow with a speed of up to 2m/s. This fluid flow is sufficient to provide adequate mixing effects without the need for additional equipment. Email :tob.amy@tobmachine.c...

  • Factors Influencing the Cycle Life of Lithium-ion Batteries
    Factors Influencing the Cycle Life of Lithium-ion Batteries Feb 28, 2024
    1.Battery material aging and decay The materials inside lithium batteries mainly include: positive and negative electrode active materials, binders, conductive agents, current collectors, separators, and electrolytes. During the use of lithium batteries, these materials undergo a certain degree of decay and aging. Tang Zhiyuan et al. believed that the factors causing capacity decay in manganese acid lithium batteries include dissolution of the positive electrode material, phase changes in the electrode material, electrolyte decomposition, formation of an interfacial film, and corrosion of the current collector. Vetter et al. systematically and deeply analyzed the changes in the positive electrode, negative electrode, and electrolyte of the battery during cycling. The author believed that the formation and subsequent growth of the SEI film on the negative electrode would be accompanied by irreversible loss of active lithium, and the SEI film did not possess true solid electrolyte functionality. The diffusion and migration of substances other than lithium ions would lead to gas generation and particle rupture. In addition, changes in material volume during cycling and the precipitation of metal lithium would also lead to capacity loss. 2. Charge and discharge system  The charge and discharge system mainly includes three aspects: charge and discharge method, rate, and cut-off conditions. Regarding the charge method, American scientist Mas proposed the concept of an optimal charging curve. He believed that the optimal charging current of a battery gradually decreases as the charging time increases, which can be expressed by the formula I=I0e-αt. In this formula, I represents the receivable charging current; I0 represents the maximum initial current at the time t=0; t represents the charging time; and α represents the decay constant. The relationship curve between I and t is shown in follow Figure. 3.Temperature Different types of lithium batteries have different optimal operating temperatures, and both excessively high and low temperatures can have an impact on the service life of the batteries. 4.Cell Consistency Battery packs typically consist of hundreds or even thousands of individual cells connected in series or parallel. In addition to the aforementioned factors influencing their cycle life, cell consistency is another crucial factor. Due to differences in materials and manufacturing processes, it is challenging to ensure the consistency of lithium-ion battery cells. In terms of materials, the uniformity of positive and negative electrode materials and electrolytes is crucial. Lithium batteries produced from the same materials and in the same batch often exhibit relatively better consistency. In terms of manufacturing, the production process of lithium batteries is complex, involving multiple process parameters at each step. Poor control can lead to inconsistencies in parameters such as battery voltage, capacity, and internal resistance. E...
