Abstract
Aspects of the disclosure relate to an insulator configured to attach to and extend along a length of a current collector of a battery cell. The insulator may include a body configured to prevent contact between the current collector and a housing of the battery cell. The insulator may include an attachment feature at a first end of the body. The attachment feature may be configured to attach the body to a first end of the current collector. The insulator may include a protrusion at a second end of the body. The protrusion may be configured to prevent rotation of the body with respect to the current collector.
Claims19
An apparatus, comprising:
- an insulator configured to attach to and extend along a length of a current collector of a battery cell,
- wherein the insulator comprises:
- a body configured to prevent a contact between the current collector and a housing of the battery cell;
- at least one attachment feature at a first end of the body, the at least one attachment feature configured to attach the body to a first end of the current collector;
- and
- at least one protrusion at a second end of the body, the at least one protrusion configured to prevent rotation of the body with respect to the current collector.
A battery cell, comprising:
- an insulator configured to attach to and extend along a length of a current collector of the battery cell,
- wherein the insulator comprises:
- a body configured to prevent a contact between the current collector and a housing of the battery cell;
- at least one attachment feature at a first end of the body, the at least one attachment feature configured to attach the body to a first end of the current collector;
- and
- at least one protrusion at a second end of the body, the at least one protrusion configured to prevent rotation of the body with respect to the current collector.
A method, comprising:
- welding a current collector of a battery cell to an electrode stack for the battery cell;
- attaching an insulator to the current collector, wherein the insulator comprises at least one attachment feature at a first end and at least one protrusion at an opposing second end, the at least one protrusion configured to prevent rotation of the insulator with respect to the current collector;
- and
- inserting, into a housing for the battery cell, the electrode stack with the current collector welded thereto and having the insulator attached to the current collector, wherein, during the inserting, the insulator prevents contact between the current collector and the housing of the battery cell.
