Abstract: Disclosed is a universal jig for charging and discharging a secondary battery cell. The universal jig includes a cell zig assembly including: a cell receiving part for receiving the secondary battery cell thereon; and a zig for a positive electrode terminal and a zig for a negative electrode terminal disposed above the cell receiving part and in contact with a positive electrode terminal and a negative electrode terminal of the secondary battery cell to apply current thereto, respectively; and a zig rotation inducing assembly connected, via a rotation center shaft thereof, to one face or an opposite face of the cell zig assembly on which the zig for the positive electrode terminal and the zig for the negative electrode terminal are disposed, wherein the zig rotation inducing assembly allows the cell zig assembly to rotate around the rotation center shaft.

Abstract: A formation apparatus for performing a charging and discharging test of a cylindrical secondary battery is disclosed. The cylindrical secondary battery includes a cylindrical body, and a positive electrode plate disposed on a top face of the body and a negative electrode plate disposed on the top face of the body. The formation apparatus includes a battery array tray on which a plurality of cylindrical secondary batteries are seated on and are arranged in a matrix form, a secondary battery contact device disposed above the battery array tray, wherein the secondary battery contact device includes a plurality of charging and discharging channels, a power supply disposed above the secondary battery contact device to supply power for the charging and discharging test to each of the plurality of charging and discharging channels, and a heat-dissipating fan facing toward the power supply to prevent overheating of the power supply.
