Abstract

A tray for accommodating a secondary battery is provided, the tray including a plurality of accommodation parts in which secondary batteries are accommodated, wherein each of the accommodation parts includes a bottom portion on which the secondary battery is mounted, sidewalls protruding from the bottom portion and supporting side surfaces of the secondary battery, and a protrusion protruding towards each of the accommodation parts on the sidewalls.

First claim

What is claimed is:

1 . A tray for accommodating a secondary battery, the tray including a plurality of accommodation parts in which secondary batteries are accommodated,
wherein each of the accommodation parts includes a bottom portion on which the secondary battery is mounted, sidewalls protruding from the bottom portion and supporting side surfaces of the secondary battery, and a protrusion on at least one of the sidewalls protruding towards each of the accommodation parts.

2 . The tray of claim 1 , wherein the secondary battery comprises:
an electrode assembly including a first electrode plate, a separator, and a second electrode plate; a case accommodating the electrode assembly and having a bottom surface, a pair of long side surfaces and a pair of short side surfaces bent from the bottom surface and extending therefrom; a cap plate coupled to the case to seal the case and having a short-circuit hole; and a first electrode terminal and a second electrode terminal electrically connected to the electrode assembly and protruding through the cap plate.

3 . The tray of claim 2 , wherein the sidewalls include a first sidewall contacting the first electrode terminal, a second sidewall contacting the second electrode terminal, a third sidewall contacting the pair of short side surfaces of the case, and a fourth sidewall contacting a bottom surface of the case, and wherein the protrusion is formed on the first sidewall.

4 . The tray of claim 2 , wherein the protrusion is proximate the first electrode terminal and contacts the cap plate.

5 . The tray of claim 2 , wherein a short-circuit plate for short-circuiting the second electrode terminal and the cap plate upon over-charging of the secondary battery is formed at the second electrode terminal.

6 . The tray of claim 5 , wherein the short-circuit plate includes a first short-circuit plate coupled to the short-circuit hole of the cap plate and downwardly convexly formed in a first direction and a second short-circuit plate coupled to the second electrode terminal, spaced from the first short-circuit plate, and extending to cover the short-circuit hole, and wherein the first short-circuit plate is configured to contact the second short-circuit plate upon over-charging of the secondary battery.

7 . The tray of claim 3 , wherein a first separating groove is formed between the first sidewall and the second sidewall, and a second separating groove is formed at a location of the fourth sidewall corresponding to the first separating groove.

8 . The tray of claim 1 , wherein a support member is adjacent to the bottom portion.

9 . The tray of claim 8 , wherein a plurality of trays are vertically stacked and the support member contacts the secondary battery positioned under each of the trays.

10 . The tray of claim 1 , wherein support grooves are formed on at least three corners of the tray.
