1. A battery comprising:
a battery cell within a battery housing; and
a headspace insulator inserted between the battery cell and a top cover, the headspace insulator including an upper insulator portion, a lower insulator portion, and a neck joining the upper insulator portion and the lower insulator portion, wherein the upper insulator portion comprises a first planar surface and a second planar surface, wherein the neck exerts a compressive force against the lower insulator portion to retain the lower insulator portion against the battery cell, wherein the upper insulator portion includes a first plurality of openings and the lower insulator portion includes a second plurality of openings, wherein the first and the second plurality of openings are configured to provide electrolyte to the battery.
