Disclosed is a cylindrical secondary battery module. A cylindrical secondary battery module according to an embodiment of the present invention is characterized by comprising: a plurality of cylindrical secondary battery cells having a battery case that accommodates both an electrode assembly and an electrolyte solution; a cell frame in which the plurality of cylindrical secondary battery cells are arranged; and a cover coupled to the cell frame and having a fire-discharging hole formed therein, wherein the cell frame is provided with: a plurality of plate-shaped members that are bent and coupled so as to intersect with each other; and spaces formed between the plurality of plate-shaped members so that the cylindrical secondary cells can be disposed therein.
Description
technical field [0001] This application claims priority from Korean Patent Application No. 10-2017-0129093 filed in Korea on October 10, 2017, the disclosure of which is incorporated herein by reference. [0002] The present invention relates to a cylindrical secondary battery module and a method of manufacturing the cylindrical secondary battery module, and more particularly, to a method capable of preventing the spread of flames generated at secondary battery cells and enabling cylindrical secondary battery cells to be set therein. A cell frame of a battery cell is easy to manufacture a cylindrical secondary battery module and a method of manufacturing the cylindrical secondary battery module. Background technique [0003] With the development of technology and the increase in demand for mobile devices, the demand for secondary batteries as energy sources is rapidly increasing. Generally, nickel-cadmium batteries or hydrogen-ion batteries have been used as secondary batte...
