  • Brief description of the production process of lithium battery cells
    Brief description of the production process of lithium battery cells Jun 28, 2021
    The cathode materials of lithium batteries are lithium cobalt oxide LiCoO2, ternary material NiMnCo, lithium manganese oxide LiMn2O4, and add conductive agent and binder, and coated on aluminum foil to form a cathode electrode. The anode electrode is coated with layered graphite plus conductive agent and binder on the copper foil, the more advanced anode layered graphite particles have adopted nano-carbon. 1. Slurry mixing: Use a special solvent and a binder to mix with the powdered cathode or anode active materials, and mix them evenly to make a slurry of cathode or anode materials. 2. Coating: The cathode or anode electrode slurry is uniformly coated on the surface of the metal foil by an automatic coating machine, and the cathode or anode electrodes are automatically cut into cathode or anode electrode sheet after automatic drying. 3. Assembly: According to the top-down sequence of cathode electrode sheet-separator-anode electrode sheet-separator, the electrolyte is injected, sealed, and the cathode or anode tabs are welded to complete the assembly process of the battery to make a finished battery. 4. Formation: put the finished battery in the tester for charge and discharge test, screen out the qualified finished battery. TOB NEW ENERGY LIMTED can supply full set of lithium battery equipment and materials, if you are interested in it, please feel free to contact us, looking forward to discuss with you.

  • NMP solvent sent to the customer's battery factory
    NMP solvent sent to the customer's battery factory May 28, 2021
    Today, a batch of lithium battery grade NMP solvent is ready to be shipped to our customer's factory. NMP is a nitrogen heterocyclic compound with a series of excellent physical and chemical properties. It is non-toxic, high boiling point, strong polarity, low viscosity, low corrosiveness, high solubility, low volatility, good stability, and easy to recycle efficient and selective solvent. NMP is a very important auxiliary material for the production of lithium-ion battery electrodes. It is a solvent commonly used in the front-end batching process of lithium-ion batteries. It is commonly known as methyl and its molecular formula is C5H9NO. In the mixing stage: as a PVDF solvent, it participates in the dispersion of the slurry to form a uniform medium and maintains a stable slurry for a long time within a certain viscosity range In the coating stage: as the main liquid carrier of the slurry, it is uniformly coated on the metal substrate with a stable thickness, and it is required to have very good wettability and fluidity with the metal substrate In the baking stage of the coating process: the wet film runs at a uniform speed in the oven, the solvent volatilizes regularly, NMP is responsible for the pore-making function, and the NMP volatilizes from the wet film at a stable speed to form a porous microelectrode structure with uniform pore size and uniform distribution .

  • Lithium ion Battery Conductive Agent
    Lithium ion Battery Conductive Agent May 10, 2021
    As an important part of the lithium ion battery, the conductive agent, although it occupies a small amount in the battery, it greatly affects the performance of the lithium ion battery, and it plays an important role in improving battery cycle performance, capacity utilization, rate performance and so on. The primary function of the conductive agent is to improve the electrical conductivity of the electron.In order to ensure that the electrode has a good performance of charge and discharge, a certain amount of conductive agent is usually added during the production of the electrode sheet to collect micro-current between the active substances and between the active substances and the fluid collector, so as to reduce the contact resistance of the electrode and accelerate the movement rate of electrons. In addition, the conductive agent can also improve the processability of the electrode sheet, promote the infiltration of electrolyte to the electrode sheet, and effectively improve the migration rate of lithium ions in the electrode material, reduce the polarization, so as to improve the charge and discharge efficiency of the electrode and the service life of the lithium battery. Conducting agents mainly include granular conductive agents such as acetylene black, carbon black, etc., conductive graphite is mostly artificial graphite, fibrous conductive agents such as metal fibers, carbon fiber grown by gas phase method, carbon nanotubes, etc., and new graphene and its mixed conductive paste are used as conductive agents.
