Lithium ion battery positive plate, preparation method of lithium ion battery positive plate, and lithium ion battery

The invention discloses a lithium ion battery positive plate, which comprises a positive current collector and a positive active layer coating the surface of the positive current collector, the positive active layer comprises the following raw materials in parts by mass: 0.9-1.5 parts of a positive binder, 0.6-1 part of carbon nanotubes, and 90-100 parts of positive active materials, the lithium ion battery positive plate selects the carbon nanotubes as a conducting agent, the conductivity of the carbon nanotube is excellent, the tubular structure cannot collapse during repeated charging and discharging processes; compared with a traditional conducting agent, by adopting the carbon nanotubes, the cyclic performance of the battery adopting the lithium ion battery positive plate can be effectively improved, the effects of reducing internal resistance and reducing polarization can also be achieved, so that the battery safety performance of the lithium ion battery positive plate can be improved.
