A sodium or potassium battery is provided, prior to an initial charge and discharge cycle, with a halogen salt additive. As is conventional, the battery is made up of the following components: an anode, a cathode, and an electrolyte. In addition, the battery includes a halogen salt (MX), where M is a metal and X is a halogen element. The halogen salt is added to the anode, the cathode, the electrolyte, or combinations thereof. The concentration MX with respect to the component(s) to which it is added is in the range of 0.01% to 10% in weight. The element X can be selected from the group of halogen elements listed in the Periodic Table. M is a material such as lithium, sodium, potassium, cesium, magnesium, calcium, barium, titanium, manganese, iron, cobalt, nickel, copper, zinc, ammonium, or combinations thereof. Advantageously, the electrolyte may be either aqueous or non-aqueous.
