## Abstract

A battery pack includes one or more battery cells including a plurality of electrode tabs, a protective circuit module connected to the electrode tabs of the one or more battery cells, a frame accommodating the battery cells and the protective circuit module, and a protective tape covering the protective circuit module and the electrode tabs, a first surface of the protective tape including a plurality of grooves corresponding to the electrode tabs.

## Claims

### Claim 1

A battery pack, comprising:
one or more battery cells including a plurality of electrode tabs;
a protective circuit module connected to the electrode tabs of the one or more battery cells;
a frame accommodating the battery cells and the protective circuit module; and
a protective tape covering the protective circuit module and the electrode tabs, a first surface of the protective tape including a plurality of grooves corresponding to the electrode tabs.

### Claim 2 (depends on 1)

The battery pack as claimed in claim 1, further comprising a label configured to fix the battery cells and the protective circuit module to the frame, a portion of the label being connected to a second surface of the protective tape.

### Claim 3 (depends on 2)

The battery pack as claimed in claim 2, wherein an interface between the second surface of the protective tape and the portion of the label connected to the protective tape is planar.

### Claim 4 (depends on 1)

The battery pack as claimed in claim 1, wherein depths of the grooves are equal to heights of the electrode tabs protruding from the protective circuit module.

### Claim 5 (depends on 1)

The battery pack as claimed in claim 1, wherein the protective tape further comprises a porous structure for emitting heat generated from the protective circuit module.

### Claim 6 (depends on 1)

The battery pack as claimed in claim 1, wherein the protective tape includes:
a first protection layer positioned on the protective circuit module and having the plurality of grooves corresponding to the electrode tabs; and
a second protection layer positioned on the first protection layer to cover the electrode tabs.

### Claim 7 (depends on 6)

The battery pack as claimed in claim 6, wherein a thickness of the first protection layer equals a height of the electrode tabs protruding from the protective circuit module.

### Claim 8 (depends on 7)

The battery pack as claimed in claim 7, wherein each of the first protection layer and the electrode tabs is positioned directly on a same layer, and a top surface of the first protection layer and a top surface of the electrode tabs are coplanar.

### Claim 9 (depends on 6)

The battery pack as claimed in claim 6, wherein each of the first protection layer and the second protection layer includes polycarbonate (PC), polyethyleneterephthalate (PET), and/or a polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS).

### Claim 10 (depends on 1)

The battery pack as claimed in claim 1, wherein the protective tape includes polycarbonate (PC).

### Claim 11 (depends on 1)

The battery pack as claimed in claim 1, wherein the protective tape is transparent.

### Claim 12 (depends on 1)

The battery pack as claimed in claim 1, wherein an entire second surface of the protective tape is flat, the second surface being opposite the first surface, and an entire portion of the first surface of the protective tape between adjacent grooves is flat.

### Claim 13 (depends on 1)

The battery pack as claimed in claim 1, further comprising a label directly on the protective tape, an entire contact surface between the label and the protective tape being flat and parallel to the protective circuit module.

### Claim 14 (depends on 13)

The battery pack as claimed in claim 13, wherein an entire contact surface between the protective tape and the protective circuit module is flat.
