Abstract: An electrochemical storage cell is disclosed which includes at least one cathode sheet, at least one anode sheet and at least one separator sheet combined to make a core. The core is housed within a rectangular shell with four sides and two ends, sealed with an air-tight seal. The cell further includes a blow out vent in at least one of the two ends of the shell. This blow out vent is adapted to open and release excess pressure above a predetermined level to thereby prevent catastrophic rupture of the shell.

Abstract: An electrochemical storage cell having a coiled core is disclosed. The coiled core includes a cathode sheet, an anode sheet, and a separator sheet. An anode connector is connected with the anode sheet at a first end of the coiled core and a cathode connector is connected with the cathode sheet at a second, opposite end of the coiled core. The coiled core has a length Lcore and a width Wcore and each connector has a width Wconnector. The length of the coiled core Lcore, width of the coiled core Wcore, and width of each connector Wconnector have the relationship 0core-Wconnector)/Lcore
