Fused Zirconium Dioxide/Yttria Stabilized Zirconium/Acetylene Carbon Black

Special Conductive Carbon Black of Lithium Battery

Special Conductive Carbon Black of Lithium Battery

Our company has actively developed a new energy strategy for requirement based on the national situation. Through a long—term cooperation with several national lithium battery manufacturers, we have been going on continual technological communications in order to accumulate and carry out deeper research on the applied mechanism of acetylene black in the lithium battery. We have been investing equipment constantly and improving as well as optimizing production engineering. As a result, we develop and produce high-quality acetylene black( powder and granular) which could apply to different kinds of lithium batteries( primary and the secondary as well as polymer lithium batteries). And our products become largely popular among our customers.

    

I.The physicochemical properties of conductive carbon black:

Compared with other carbon black, granular has small size while big proportion, which owns good properties of specific surface area and absorption. The structure of high chain is excellent, making it easier to form more conductive paths. It has high thermal conductivity and stable chemical property. In addition, the surface activity and conductivity are quite good. Its purity is above the average with fewer impurities, such as heavy metal. The value of  Ph is between 8.2 and 9.2.


Compared with powder acetylene black, the granular carbon black has a small volume and big proportion. It possesses the merits of little dust pollution and good mobility as well as superior dispersion.


II.The integrated electrical performance of lithium battery:

1. Thanks to acetylene black have larger surface area than graphite and Super P products, which urges graphite to improve its circulation property. The specific surface area is big which can increase the area of electrochemical reaction and reduce the impedance of this reaction. Besides, it levels up the acceptable ability of battery charging and strengthens the conductive property.

2. Because the particles of carbon black are small, the exertion of volume per gram can be increased.

3. It can decrease the dosage of conductive agent.

4. It can enhance the density of high—rate discharge power.

5. It has strong absorption which can raise electrolyte absorption.

6. It can increase the cycle service life

7. Owing to its high thermal conductivity, it can raise the safety property.
