▎ 摘　　要

NOVELTY - A conductive paste comprises conductive agent, solvent and micro-bubble. The conductive agent comprises graphene and carbon nanotubes. The particle diameter of microbubble is less than 100 micromand the concentration of the microbubbles is greater than 106 per ml. The mass content of the conductive additives is between 0.5-8 wt.%. USE - The conductive paste is useful for battery pole piece which is useful in a battery electrode preparation process, where the battery is a lithium-ion battery. ADVANTAGE - The conductive paste containing micro-bubble is very easy to store, placing for several months without generating precipitate, meeting the need for placing for a period of time in the storage and transportation of the paste, avoids the problem that the existing graphene dispersion needs to be used after dispersing treatment, and can be directly used for electrode preparation of battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a preparation method of conductive paste; (2) an electrode paste; (3) a battery pole piece; and (4) a battery. DESCRIPTION OF DRAWING(S) - The drawing shows a preparation process step diagram of the conductive paste. (Drawing includes non-English language text).
