## Abstract

A rechargeable battery including: a case; an electrode assembly including a plurality of electrode sub-assemblies accommodated in the case; a plurality of terminals electrically connected to the electrode assembly; a cap plate sealing the case; and an insulation plate between the electrode assembly and the terminals and being hingedly coupled to the cap plate. The terminals protrude through the cap plate.

## Claims

### Claim 1

A rechargeable battery comprising:
a case;
an electrode assembly comprising a plurality of electrode sub-assemblies accommodated in the case;
a plurality of terminals electrically connected to the electrode assembly;
a cap plate sealing the case and comprising protrusions protruding from a bottom surface of the cap plate toward the electrode assembly in the case, the terminals protruding through the cap plate; and
an insulation plate between the electrode assembly and the terminals and being hingedly coupled to the cap plate, the insulation plate comprising recessed coupling grooves at regions corresponding to the protrusions, the protrusions being hingedly coupled to the insulation plate at the recessed coupling grooves such that the insulation plate is configured to pivot relative to the cap plate.

### Claim 2 (depends on 1)

The rechargeable battery of claim 1, wherein the insulation plate is configured to pivot in a widthwise direction of the cap plate.

### Claim 3 (depends on 1)

The rechargeable battery of claim 1, wherein the protrusions are at opposite edges of the cap plate in a lengthwise direction thereof.

### Claim 4 (depends on 1)

The rechargeable battery of claim 1, wherein the protrusions are at a central region of the cap plate in a lengthwise direction thereof.

### Claim 5 (depends on 1)

The rechargeable battery of claim 1, wherein ends of the protrusions have a cone, a curve, or a polygon shape.
