Abstract
A battery includes a cell casing that has recessed portion on a major surface of the casing, the recessed portion being substantially planar and bordering a remainder of the major surface at a ridge portion on each of one or two sides of the recessed portion, whereby the recessed portion, the ridge portions, and the remainder of the major surface cooperate under an increase of gauge pressure to cause a plane defined by a boundary between the ridge portions and the remainder of the major surface to move.
Claims26
A battery casing having a recessed portion on a major surface of the casing, the recessed portion being substantially planar and bordering a remainder of the major surface at a ridge portion on each of one or two sides of the recessed portion, whereby the recessed portion, the ridge portions, and the remainder of the major surface cooperate under an increase of gauge pressure to cause a plane defined by a boundary between the ridge portions and the remainder of the major surface to move.
The battery casing, wherein the ridge portions oppose each other.
A battery, comprising:
- a) a first terminal in electrical communication with a first electrode of the battery;
- b) a second terminal in electrical communication with a second electrode of the battery;
- and
- c) a battery can having a cell casing and a lid, which are in electrical communication with each other, the battery can being electrically insulated from the first terminal, wherein the cell casing has a recessed portion on a major surface of the casing, the recessed portion being substantially planar and bordering a remainder of the major surface at ridge portions on at least three sides of the recessed portion, whereby the recessed portion, the ridge portions, and the remainder of the major surface cooperate under an increase of gauge pressure to cause a plane defined by a boundary between the ridge portions and the remainder of the major surface to move.
A battery casing having a plurality of recessed portions on a major surface of the casing, the recessed portions being substantially planar and bordering a remainder of the major surface at ridge portions of the recessed portion, wherein at least a portion of the ridge portions are parallel to each other.
