## Abstract

Provided is a gripper assembly for battery charging/discharging, which is electrically connected to a battery electrode to apply current during battery charging/discharging operation, the gripper assembly including a first electrode lead gripper including a first electrode gripper body disposed to correspond to a first electrode lead of the battery, and a first contact member coupled to one side of the first electrode gripper body and pressed to contact a surface of the first electrode lead and a second electrode lead gripper including a second electrode gripper body disposed to correspond to a second electrode lead of the battery, and a second contact member coupled to a side of the second electrode gripper body and attached to contact a surface of the second electrode lead.

## Claims

### Claim 1

A gripper assembly for battery charging/discharging, electrically connected to a battery electrode to apply current during battery charging/discharging operation, the gripper assembly comprising:
a first electrode lead gripper comprising a first electrode gripper body disposed to correspond to a first electrode lead of the battery, and a first contact member coupled to one side of the first electrode gripper body and pressed to contact a surface of the first electrode lead; and
a second electrode lead gripper comprising a second electrode gripper body disposed to correspond to a second electrode lead of the battery, and a second contact member coupled to a side of the second electrode gripper body and attached to contact a surface of the second electrode lead,
wherein the first contact member is formed of a metallic material, and the second contact member is formed of a conductive resin.

### Claim 2 (depends on 1)

The gripper assembly of claim 1, wherein the first contact member is provided with a plurality of sharp jaws to press a surface of the first electrode lead.

### Claim 3 (depends on 1)

The gripper assembly of claim 1, wherein the first contact member is gold-plated.

### Claim 4 (depends on 1)

The gripper assembly of claim 1, wherein a bottom surface of the second contact member is formed as a horizontal surface to be attached to a surface of the second electrode lead.

### Claim 5 (depends on 1)

The gripper assembly of claim 1, wherein the first electrode is a cathode and the second electrode is an anode.

### Claim 6 (depends on 1)

The gripper assembly of claim 1, wherein the first electrode lead and the second electrode lead are disposed on both sides of the battery.

### Claim 7 (depends on 6)

The gripper assembly of claim 6, further comprising:
a supporting structure holding the battery,
wherein first and second electrode lead grippers, which are brought into contact with first and second electrode leads respectively disposed at both sides of the battery, are provided on both end portions of the supporting structure, respectively.
