Abstract: The disclosed technology relates to an electrical feedthrough for a cylindrical battery cell. The electrical feedthrough may include an annular channel having an outer sidewall, an inner sidewall, and a base; an insulator formed of glass having an overmold portion; and a pin extending through the insulator and configured to form an external battery terminal. The insulator is bonded to the inner sidewall of the annular channel and a portion of the base of the annular channel. The overmold portion prevents electrical contact between a set of electrodes and the electrode feedthrough.
