An insulation portion for an electrochemical cell having a plurality of slots into which bent electrode tabs are slid through during an assembly process of an electrochemical cell. A latch is disposed adjacent the slots and is movable from a resting position to a biased position to engage the electrode tabs. Attachment of the insulation portion to the electrochemical cell and bending of the electrode tabs can be robotically performed, such that controllers of an attachment device and bending device are in communication with each other.

Electrical insulator for electrochemical cell

An electrochemical cell includes components that are welded from an external source after the components are assembled in a cell canister. The cell canister houses electrode tabs and a core insert. An end cap insert is disposed opposite the core insert. An external weld source, such as a laser beam, is applied to the end cap insert, such that the end cap insert, the electrode tabs, and the core insert are electrically coupled by a weld which extends from the end cap insert to the core insert.
