Abstract
An improved long life, liquid activated battery is disclosed which employs a battery cell architecture including a metal electrode and a specially configured, multi-element carbon electrode. The carbon electrode is effected by activated carbon granules embedded in an electrically conductive adhesive in which the conductive component is a myriad of carbon particles. A conductor, which may be a carbon fiber material or a more conventional conductor, is connected to the adhesive and couples the carbon electrode through a barrier which isolates the cell chamber to provide one power input connection to a user device. The activated carbon granules serve the second function of a cell gas scavenger such that the need for providing a separate filter to perform this function is eliminated. Thus, a substantially monolithic carbon electrode within the cell chamber is effectively realized. The other electrode is a metal selected to obtain the desired cell voltage appropriate for the battery load. For such conventional circuits as watch and calculator modules, an alloy of magnesium is preferred to obtain a voltage output typically in the range 1.45 to 1.65 volts d-c.
