An anode casing having a bright tin or bright tin alloy surface layer at least on an inside surface of the casing, preferably on the entire surface of the anode casing, and to an electrochemical cell containing the anode casing. Methods for preparing anode casings and electrochemical cells containing the anode casings are disclosed. In a preferred embodiment, the anode casings are plated at high current density utilizing a variable contact rack plating process, wherein portions of a clamp assembly of the device variably or alternately contact different portions of the anode casing so the entire surface of the anode casing is plated. The bright tin-plated surface is a high hydrogen-overvoltage metal that reduces gassing in cells using the casings.
