METHOD FOR EVALUATING INSULATION OF OVERLAY PART

The present invention relates to a method of evaluating insulation of an overlay part, and the method includes: (a) a process of applying and drying insulation coating liquid on the electrode mixture layer to thereby simulate the overlay part, and collecting data about a length c of a gap of an applicator, a thickness d which has been increased by insulation coating, and a capacity f of the overlay part; (b) a process of applying and drying insulation coating liquid on a current collector to thereby simulate a pure insulation coating layer, and collecting data about a length g of a gap of an applicator and a thickness h of the pure insulation coating layer; (c) a process of generating a relation formula 1 between thickness H of the pure insulation coating layer and capacity F of the overlay part based on data collected through the processes (a) and (b); (d) a process of measuring a thickness of a pure insulation coating layer at an electrode for evaluation; and (e) a process of calculating the capacity of the overlay part by substituting the thickness of the pure insulation coating layer measured in the process (d) into the relation formula 1.
