Abstract
A battery module a battery cell stack in which a plurality of battery cells are stacked, a busbar frame connected to the battery cell stack, cell terraces each protruding from battery cells adjacent to each other among the battery cells included in the battery cell stack, electrode leads each protruding from the cell terraces, and an insulating adhesive layer which is located between electrode leads adjacent to each other among the electrode leads and cover the boundary between the cell terrace and the electrode lead, wherein the insulating adhesive layer is in close contact with a stepped part formed by the cell terrace and the electrode lead.
Claims12
A battery module comprising:
- a battery cell stack in which a plurality of battery cells are stacked,
- a busbar frame connected to the battery cell stack;
- and
- a plurality of cell terraces, each cell terrace of the plurality of cell terraces protruding from a respective one of the plurality of battery cells,
- a plurality of electrode leads, each electrode lead of the plurality of electrode leads protruding from a respective one of the plurality of cell terraces, and
- an insulating adhesive layer covering a boundary between the cell terrace and the electrode lead of at least one of the plurality of battery cells,
- wherein the plurality of battery cells includes a first battery cell adjacent a second battery cell, the first battery cell having a first cell terrace and a first electrode lead, the second battery cell having a second cell terrace and a second electrode lead, and
- wherein the insulating adhesive layer is in close contact with a stepped part formed by the first cell terrace and the first electrode lead.
A method for manufacturing a battery module comprising the steps of:
- stacking a plurality of battery cells to form a battery cell stack, each of the plurality of battery cells having a cell terrace and an electrode lead, the plurality of battery cells comprising a first battery cell having a first cell terrace and a first electrode lead and a second battery cell having a second cell terrace and a second electrode lead;
- and
- connecting a busbar frame to the battery cell stack;
- and
- forming an insulating adhesive layer between between the first cell terrace and the second cell terrace,
- wherein the insulating adhesive layer is located between the first electrode lead and the second electrode lead, and
- wherein the insulating adhesive layer is a one-component liquid adhesive that conforms to a step formed at a boundary between the first electrode lead and the first cell terrace.
