Lithium battery sp conductive carbon black characteristics
Feb 04, 2023
Conductive carbon black sp is agglomerated from primary particles with a diameter of about 40nm into primary aggregates of 150-200nm, and then formed through subsequent processing such as soft agglomeration and manual compression. At present, the domestic conductive agent for lithium-ion batteries is still dominated by the conventional conductive agent SP. Carbon black has better ion and electronic conductivity, because carbon black has a larger specific surface area, so it is conducive to the adsorption of electrolytes and improves ion conductivity. In addition, the carbon primary particles aggregate to form a branched chain structure, which can form a chain-type conductive structure with the active material, which helps to improve the electronic conductivity of the material.

sp conductive carbon black is a carbon black with high porosity, which can form a carbon black network structure at a very low dosage, and endow the product with excellent electrical conductivity.

Conductive carbon black is mainly used as a reinforcing agent and filler for rubber, and its usage is about half of that of rubber. Carbon black for rubber accounts for 94% of the total output, of which about 60% is used to produce tires. These products endow rubber particles with high strength and resilience, and are generally used in the tire industry, rubber seals, shock absorbers, etc. Rubber products can be used for reinforcement and filling with a certain amount of carbon black. Improve the properties of rubber products.
Pigment black is mainly used as an additive for inks, paints and plastics, as well as an ultraviolet protective agent for plastic products. Its particle size and structure are different, and its dispersion is completely different. The denser the particle size, the more surface, the stronger the cohesion between them.
It can be seen that the basic principle of carbon black for water-based coatings with good dispersibility must have a large particle size and a high structure. If you want to use gray-black plastic products, you should choose a low-carbon black structure with a smaller particle size. In order to obtain a satisfactory coloring effect, attention should be paid to the dispersibility of the black smoke pigment. Dealing with the dispersibility of smoky pigments can only get excellent coloring power.
