Patent ID: 8241525

Claim:
A method for producing a positive electrode for lithium batteries containing a positive electrode active material and a conductive material, the method comprising: (Step 1): a step of producing a composite material for positive electrodes of lithium batteries, (Step 2): a step of obtaining a slurry containing the composite material for positive electrodes of lithium batteries obtained in Step 1, a solvent, a conductive material and a binder, (Step 3): a step of applying the slurry obtained in Step 1 onto a current collector, and (Step 4): a step of drying the current collector having the slurry applied thereto and obtained in Step 3, wherein Step 1 further comprises: (Step 1-1): a dispersing step of dispersing at least the positive electrode active material and the conductive material 1 in a solvent to be in a forcibly dispersed state; and (Step 1-2): a composite particle-forming step of obtaining composite particles containing the positive electrode active material and the conductive material 1 by a process for agglutinating the conductive material 1 together with the positive electrode active material in the solvent, wherein a conductive material having autoagglutination in the solvent is used as the conductive material 1, the content of the conductive material 1 is 0.2 to 5 parts by weight relative to 100 parts by weight of the positive electrode material, and the forcibly dispersed state is a dispersion state where when a slurry is sampled and diluted to a predetermined concentration, and an average particle diameter is promptly measured by a particle size distribution measuring device, the average diameter does not surpass 130% of a primary particle diameter of the positive electrode active material.
