The full name of SP conductive carbon black is super pll conductive carbon , which is a kind of conductive carbon black similar to furnace black method. Compression and other subsequent processing molding.
Molecular structure of conductive carbon black sp
The molecular formula of conductive carbon black sp is C, and the structural formula of conductive carbon black sp is also similar to that of other carbon blacks.
Characteristics of Conductive Carbon
1. The product has extremely high purity, moderate specific surface area, excellent processing performance, and can be used in positive and negative electrodes.
2. In the case of low addition amount, it has good synergy in the electrode, which can effectively improve the battery cycle capacity and cycle life.
3. super p Black products have the characteristics of high specific surface area, high structure, high purity and excellent conductivity.
4. It has no effect on the electrochemical mechanism.
SP Conductive Carbon Black application
SP conductive carbon black belongs to the small particle pigment black, which is often used as a conductive agent. It is cheap and practical. High-efficiency superconducting pigment black for lithium batteries, branched chain, high purity, and particularly good electrical conductivity. The role of SP conductive Black in lithium batteries is to improve conductivity, and a low or very low addition of conductive carbon black sp can improve conductivity.
The role of conductive carbon black sp in lithium battery negative electrode
1. SP Conductive black is used in a low or very low addition amount in the negative electrode of lithium batteries, which can improve the conductivity of lithium batteries.
2. Ensuring contact of the active oxide particles with the current collector and better contact of the internal particles.
3. Control the porosity of the negative electrode of the lithium battery and make the electrolyte ideally contact the oxide particles.
4. No effect on the electrochemical mechanism.
The role of conductive carbon black sp in the positive electrode of lithium batteries
1. Conductive Carbon black is used in a low or very low addition amount in the positive electrode of lithium batteries to improve the conductivity of the positive electrode of lithium batteries.
2. Ensuring contact of the active oxide particles with the current collector and better contact of the internal particles.
3. Control the porosity of the positive electrode of the lithium battery and make the electrolyte ideally contact the oxide particles.
The difference between super P and acetylene black
Both super P and acetylene black are conductive carbon blacks, with a particle size of about 40 nanometers, 60 more than that of the second surface. Mesh, which forms a conductive network on the pole piece. The ash content and volatile matter (impurity) of Super P black are less. In fact, the impact of the two additives on battery performance is not much different, but Super-p is more expensive, and acetylene is mostly used in laboratory and practical production.
