Beschreibung
Zusammenfassung:	The invention discloses a homogenating method of lithium battery positive electrode slurry. The homogenating method includes: mixing an adhesive and a solvent to prepare adhesive liquid; adding carbonnanotube, superconductive carbon black and a solvent into a double-planet stirrer, heating, and stirring to obtain a wetting conductive agent; adding the adhesive liquid into the wetting conductive agent, adopting the double-planet stirrer to perform vacuum stirring operation for the first time to obtain a conductive adhesive; adding lithium iron phosphate micropowder into the conductive adhesive, and well mixing and stirring to obtain a positive electrode slurry precursor; adopting specific revolution speed and dispersion speed to perform vacuum stirring operation for the second time to obtain the lithium battery positive electrode slurry. By adopting a specific stirring process, the circumstance that molecular long chains in raw materials are broken due to stirring in the process of dispersing and stirring the
