The weather in Xiamen today is great, we also take advantage of this good weather to ship the CNT materials of our regular client's factory. Like lithium ion battery electrode materials, conductive agents are constantly evolving. 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 has very important effect on improving battery cycle performance, capacity development, rate performance, etc. From the earliest zero-dimensional conductive agent carbon black materials to conductive carbon fibers and carbon nanotubes, which are gradually developed later, conductive agents with one-dimensional structure. Carbon nanotubes, a conductive agent with a one-dimensional structure, increase the contact with the electrode material particles due to its fibrous structure, which greatly improves the conductivity of the electrode and reduces the resistance of the pole piece. CNTs can be divided into single-walled CNTs and multi-walled CNTs. Carbon nanotubes with a one-dimensional structure are similar to fibers in a long columnar shape with a hollow interior. Carbon nanotubes have good electronic conductivity. The fibrous structure can form a continuous conductive network in the active material of the electrode. It is also in the form of point-line contact with the active material, which is useful for increasing the battery capacity (increasing the compaction density of the pole piece) and rate Performance, battery cycle life and reducing battery interface impedance have a great effect. After adding carbon nanotubes, the pole piece has higher toughness, which can improve the peeling caused by the volume change of the material during the charging and discharging process, and increase the cycle life. Carbon nanotubes can greatly improve the penetration ability of the electrolyte in the electrode material. Therefore, as a conductive agent for lithium ion batteries, the main problem that CNT needs to be solved is the dispersibility of CNT, which is required to be well dispersed in the slurry. At present, it can be solved by high-speed shearing, adding dispersant, making dispersion slurry, and electrostatic dispersion of ultrafine grinding beads. CNT can more effectively improve the overall performance, which makes it a research hotspot and one of the most potential application directions of conductive agents for lithium batteries.

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.

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 .
