Abrégé

The present disclosure relates to the technical field of carbon black materials, and in particular to high-crystallinity, high-structure and high-specific-surface-area conductive carbon black, a preparation method therefor, a device, an electrode slurry, and a secondary battery. The high-crystallinity, high-structure and high-specific-surface-area conductive carbon black has a crystallinity of 42-51%, a BET specific surface area of 58-200 m2/g, and a cOAN of 108-180 mL/100 g. The conductive carbon black of the present disclosure simultaneously achieves high crystallinity, high structure, and high specific surface area. When the conductive carbon black is used as a conductive agent, on the one hand, the high crystallinity endows the conductive agent with excellent conductivity and stability and improved compatibility with an electrolyte solution; on the other hand, the structure has sufficient length, perfect network structure, and liquid absorption and retention capacity, so that the conductive carbon black has good conductivity, ion conduction capability, and dispersity and can significantly improve the performance of batteries.
