Embodiment 1
[0047] The positive electrode material of the lithium-ion battery in this embodiment is nano-lithium iron phosphate, polyvinylpyrrolidone, carbon nanotube+VGCF, L132 and deionized water according to the proportion formula of 90:1.5:5:5:77 by weight, carbon The weight ratio of nanotubes to VGCF is 1:1, and the positive current collector is made of pure aluminum foil.
[0048] The preparation method of the positive electrode includes the following steps: accurately take each component of the positive electrode material, evacuate to a vacuum degree of 0.02Mpa, mechanically stir and disperse the slurry, the revolution speed of the stirring is 20 Hz, the rotation speed is 20 Hz, and the stirring time is 5 hours , and then adjust the slurry concentration to 4000mPa.s and then coat the pole piece. The coating temperature is 70°C, the coating speed is 4m / min, and then the pole piece is dried at 70°C for 7 hours.
[0049] The slurry in this embodiment is uniformly dispersed, and the pa...
