Abstract
A battery sub-packing unit includes at least one battery cell; and a case accommodating the at least one battery cell, wherein the case comprises an end panel on which an electrode tab of the at least one battery cell is fastened to extend into an external space, and having a lower end portion in which a sub-vent hole is formed for communication between the external space and an internal space in which the at least one battery cell is disposed.
Claims16
A battery sub-packing unit comprising:
- at least one battery cell comprising an electrode tab;
- and
- a case accommodating the at least one battery cell,
- wherein the case comprises an end panel on which the electrode tab of the at least one battery cell is fastened to extend into an external space, and having a lower end portion in which a sub-vent hole is formed for communication between the external space and an internal space in which the at least one battery cell is disposed,
- wherein the battery sub-packing unit further comprises:
- an inner pad disposed in the internal space of the case, contacting the at least one battery cell accommodated in the case, and
- wherein the inner pad is configured to generate at least one of carbon dioxide or nitrogen during oxidation for filling the internal space of the case to block inflow of external oxygen,
- wherein the at least one battery cell is provided as a plurality of battery cells, and the inner pad is disposed between battery cells adjacent to each other among the plurality of battery cells, and
- wherein the inner pad comprises a pad flange portion located between electrode tabs of the plurality of battery cells adjacent to each other.
6 more elements
A battery sub-packing unit comprising:
- at least two battery cells each comprising an electrode tab;
- an inner pad separating the at least two battery cells;
- and
- a case enclosing the at least two battery cells and the inner pad;
- wherein the case comprises an accommodating can, front and rear end panels coupled to front and rear end portions of the accommodating can, and a pair of upper fastening portions extending in opposite directions from opposite side walls of the accommodating can, and
- wherein the pair of upper fastening portions are coupled to each other to secure the case around the at least two battery cells, and
- wherein the inner pad is in direct contact with the at least two battery cells and is configured to generate at least one of carbon dioxide or nitrogen during oxidation to block inflow of external oxygen inside the case, and
- wherein the inner pad comprises a pad flange portion located between electrode tabs of the at least two battery cells adjacent to each other.
