PROBLEM TO BE SOLVED: To provide a manufacturing method of an electrode for a lithium secondary battery wherein a dispersibility of electro-conductive auxiliary material powder is able to be improved in an electrode layer by the fact that the formation of an aggregate in electrode slurry is prevented and that the viscosity of the electrode slurry is reduced. SOLUTION: This is a manufacturing method of the electrode for the lithium secondary battery, wherein the electrode layer which includes at least the electrode active substance powder, the electro-conductive assistant powder, an electro-conductive high polymer material and a high polymer binding material is carried by a current collector and formed. The manufacturing method of the electrode for the lithium secondary battery is adopted which is characterized in that it consists of an electrode slurry preparation process to prepare the electrode slurry by mixing the electrode active substance powder, the electro-conductive assistant powder and the high polymer binding material into a solvent and by adding and dissolving the electro-conductive high polymer material into the solvent within a range not less than 0.05 wt.% and not more than 10 wt.%, and that it consists of an electrode manufacturing process in which the electrode layer is carried and formed on the current collector by distilling the solvent after coating the electrode slurry on the current collector. |
