Embodiment Construction

[0047] The present invention relates to a water activated delayed action cell and a method for the manufacture of a cathode for such a cell.

[0048] More specifically, the present invention relates to a delayed action battery adapted to be activated by immersion in water. For example, such batteries could be used to automatically power emergency lights and sirens on lifejackets in the event of submersion.

[0049] Embodiments of the present invention relate to such a lifesaving locator light and a battery thereof.

[0050] There are standard humidity tests that such batteries and lamps must pass, such as SAE International Aerospace Standard (AS) 4492 Survival Positioning Lights, RTCA / DO-160C and RTCA issued December 1995 and reaffirmed November 18, 2004 / DO-160E.

[0051] Areas of interest, while maintaining full compliance with international aerospace standards, are extending product life of lifesaving locator lights in high humidity environments, shortening soak-to-light ...

Abstract

A Water Activated Battery characterized by a) At least one anode selected from the group consisting of magnesium, aluminum, zinc and alloys thereof; b) A cathode comprising at least one basic copper salt comprising Cu(OH) 2 combined with a copper salt CuX (with (n-1) the molar ratio between the CuX and the Cu(OH) 2 in the basic copper salt), such that a discharge reaction in saline versus a Mg anode could be written nMg + Cu(OH) 2. (n-1)CuX = Mg(OH) 2 + (n-1)MgX + nCu) on a skeletal frame, the cathode further comprising a non-hygroscopic soluble, ionically conductive material; c) at least onecavity separating said cathode and said at least one anode; and d) at least one aperture leading to said at least one cavity for the ingress of an electrolyte-forming, aqueous liquid.

Description

technical field [0001] The invention relates to the field of battery-driven lights, in particular to the cathode formula of a lifesaving positioning light. Background technique [0002] Passengers and crew or crew of aircraft and seagoing vessels must be equipped with lifejackets with survival locator lights powered by water-activated batteries (WAB). Water-activated batteries for marine applications generally include lithium-based power cells that are safe, reliable and economical. However, lithium-based power batteries are banned from being used in aircraft's water-activated batteries due to the potential for explosion. In contrast, water-activated batteries have been developed that contain dry electrodes connected to lamps such that immersion in water causes water to enter the pores in the water-activated battery casing, filling the gaps between the electrodes and dissolving the salt contained in the water-activated battery to provide ions, This creates an ionic current...
