PURPOSE: A manufacturing method of an electrode formulation is provided to be able to improve the uniformity of the electrode formulation by passing the electrode formulation through a micro-tube with high pressure and mixing, and therefore, to be able to improve the durability and performance of a battery. CONSTITUTION: A manufacturing method of an electrode formulation for a secondary battery which is coated on one side or both sides of an electrode current collector comprises (i) a step of adding an electrode active material, a conductive material and a binder in a solvent; (ii) a step of firstly mixing the mixture of step (i), and (iii) a step of passing the mixture of step (ii) through a micro-tube with high pressure. The manufacturing method mixes the active material, the conductive material, the binder and the solvent at once. The solvent is N-methyl-2-pyrrolidone or methyl ethyl ketone. An electrode for a secondary battery is coated with said manufactured electrode formulation on the electrode current collector. [Reference numerals] (AA) Comparative example 1; (BB) Example 1 |
