The disclosure provides electrochemical batteries, electrochemical battery housings and methods for assembling electrochemical batteries. The battery housing can include a container, a container lid assembly and an electrical conductor. The container can include a cavity that extends into the container from a cavity aperture. The lid assembly can seal the cavity, and can include an electrically conductive container lid and an electrically conductive flange. The container lid can cover the cavity aperture and can include a conductor aperture that extends through the container lid. The flange can cover the conductor aperture and can be electrically isolated from the container lid. The conductor can be connected to the flange and can extend through the conductor aperture into the cavity. The conductor can be electrically isolated from the container lid.
