Problems solved by technology
The invention discloses a preparation method of a lithium iron phosphate positive electrode material slurry; the positive electrode material slurry is composed of lithium iron phosphate, a binder, a conductive agent and a solvent; the preparation method comprises the step of mixing the components in the positive electrode material slurry, wherein the mixing comprises four processes of adhesive solution preparation, conductive agent dispersion, lithium iron phosphate dispersion and dilution stabilizing. The conductive adhesive solution is added step by step into a lithium iron phosphate powder, and with use of shearing action of a device on a high-solid-content dispersion system, the acting force between particles and the acting force between the particles and the device are increased so as to achieve an excellent dispersion effect.
