Primary battery of the remotely activated type with acid electrolyte

Abstract From the Canadian patent

The present invention includes a primary battery of the remotely activated type which may include one or more zinc electrodes and which is filled with a liquid electrolyte only when the battery is to be activated. A novel feature of the invention is the use of an acid or mixture of acids in aqueous solution as the electrolyte. Hydrochloric acid phosphoric acid, and sulfuric acid are preferred although other acid can also be, used in various concentrations as the electrolyte. The voltage of the battery is unexpectedly higher and the battery has a faster activation time at low temperatures than if an alkaline electrolyte were used. A superior high voltage short diration battery is thus …
