Abstract
The tape cell battery system comprises an elongated strip of flexible tape divided into segmented sections of anode, cathode and fluid electrolyte. The electrolyte is stored in a separated segment sealed from the segment containing the anode and cathode. The tape is advanced through nip rolls to individually break open each sealed segment containing electrolyte such that the electrolyte is caused to flow into a single adjacent segment containing said anode and cathode such that only one battery cell at a time becomes electrochemically active while the other battery cells remain electrochemically dormant.
Claims17
A tape cell battery system comprising an elongated strip of flexible tape composed of a plurality of discrete sections with each section of tape including an anode, a cathode, a fluid electrolyte and means for storing said electrolyte so that it is isolated from said anode and said cathode and with said system further comprising means for accessing said electrolyte in each section to enable each section to become electrochemically active while the other sections remain electrochemically dormant and means for advancing said tape in succession as each preceding section is electrochemically discharged with said elongated strip of flexible tape being interconnected to a strip of inactive material which functions as a leader in establishing a sequence for initially activating a section of said tape wherein said strip of flexible tape is interconnected to itself and to said strip of inactive material to form of an endless loop.
A tape cell battery system comprising a single compartment housing an elongated strip of flexible tape interconnected as an endless loop, means for separating said tape into segmented sections containing an anode, a cathode and fluid electrolyte and means for forming a weak seal of predefined strength between each segment containing said fluid electrolyte and an adjacent segment containing an anode and cathode so as to form a plurality of electrochemically dormant battery cells and means for individually opening each weak seal in each battery such that only one battery cell at a time becomes electrochemically active while the other battery cells remain electrochemically dormant.
A tape cell battery system comprising an elongated strip of flexible tape composed of a plurality of segmented sections with each segmented section of tape consisting of a plurality of discrete battery cells with each cell having an anode and a cathode and wherein each section of tape contains fluid electrolyte to electrochemically activate the anode and cathode in each of the battery cells and with said system further comprising means for electrically connecting said plurality of discrete battery cells in each section in a series and/or parallel arrangement, means for advancing said tape in succession and a strip of inactive material connected to said strip of tape and functioning as a leader for establishing a sequence for advancing each section of tape in said tape battery cell system wherein said strip of flexible tape is interconnected to itself and said strip of inactive material in the form of an endless loop.
