NOVELTY - The assembly has a first electrode lead gripper (120) which includes a first electrode gripper body (121) corresponding to a first electrode lead (11) of a battery (10), and a gold-plated first contact member (122) coupled to one side of the first electrode gripper body and pressed to contact a surface of the first lead. A second electrode lead gripper (130) has a second electrode gripper body (131) corresponding to a second electrode lead (12) of the battery, and a second contact member (132) coupled to a side of the second gripper body and attached to contact a surface of the second lead.    USE - Gripper assembly for battery charging/discharging in portable electronic devices. Uses included but are not limited to mobile phone, personal digital assistant (PDAs), Smart phones and laptop computers.    ADVANTAGE - Provides a gripper assembly in which current and voltage grippers press the cathode and anode leads of a battery cell to perform charging/discharging operation, and the current and voltage grippers are gold-plated to enhance conductivity. Prevents the second electrode lead from being scratched and also prevents the first electrode lead gripper from being worn out, thus, the jig device may stably fix the battery disposed on the bottom surface of the supporting structure, and thus enhancing stability during charging/discharging operation. The gripper assembly prevents scratches on the electrode lead and also prevents the gripper from being worn out and the gold-plated layer from being damaged by developing the gripper assembly such that the electrode lead grippers is attached to contact one electrode lead of the battery.
