Conductive slurry for battery pole piece, battery pole piece and battery
ActiveCN114023968AUniform and stable dispersionEasy to storeMaterial nanotechnologyElectrode manufacturing processesConductive pasteCarbon nanotube
The invention discloses conductive slurry for a battery pole piece, the battery pole piece and a battery, the conductive slurry for the battery pole piece is composed of a conductive agent, a solvent and fine bubbles, and the conductive agent comprises graphene and carbon nanotubes; the particle size of the micro-bubbles is less than 100 microns, and the concentration of the micro-bubbles is greater than 106 / ml; and the mass content of the conductive agent is between 0.5 wt.% and 8 wt.%. When the obtained conductive paste is used in the actual battery electrode preparation process, the conductive paste containing the micro-bubbles is very easy to store and does not generate precipitates after being placed for several months, and the requirement that the conductive paste needs to be placed for a period of time in the storage and transportation process is met. The problem that the existing graphene dispersion liquid can be used only after dispersion treatment is avoided, and the graphene dispersion liquid can be directly used for preparing the electrode of the battery.
