Abstract: A mandrel for manufacturing an electrode assembly includes a first mandrel member having a semicircular cross-section and a predetermined length, and a second mandrel member configured to define a cylindrical shape of the mandrel by being coupled to the first mandrel member while facing the first mandrel member. A concave-convex part is provided on joint surfaces of the first and second mandrel members. The concave-convex part includes a protrusion and a groove formed in a longitudinal direction so as to engage with each other.

Abstract: A cutting apparatus and a method for chamfering a film stack using the cutting apparatus. The chamfering method reduces microcracks generated in the film stack during curved surface chamfering, reduces the maximum stress applied to the film stack, prevents lifting, and enables processing of a curved surface.

Abstract: The present application relates to a mixer and a mixing method and, more specifically, to a pipe-type mixer for low-flow dispersion of immiscible liquids. The mixer, according to the present application, comprises: a pump (30) provided in a liquid transport section so as to supplement a deficient flow velocity, when materials to be mixed such as liquids are mixed through a continuous mixing step; and static mixers (22) suitable for the dispersion of the materials to be mixed by increasing a diameter of mixing parts (20) provided in a circulation pipe (10). Thus, a mixing rate of mixed materials can be more efficiently increased when the materials are mixed by using the static mixers (22).

Abstract: The present invention relates to a stirrer having grooves formed on the inside of a container in order to improve the degree of mixing, and the stirrer which is provided comprises: a plurality of projections formed on the inner surface of a stirrer container; and a plurality of grooves formed between the plurality of projections.
