Patent ID: 7592097

Claim:
An electrochemical cell, comprising: a) a casing of electrically conductive material; b) first and second opposite polarity electrodes housed inside the casing in electrical association with each other and having a separator disposed there between, wherein each of the electrodes includes a current collector; c) an electrolyte activating the first and second electrodes; d) at least one of the first and second electrodes comprising a first plate, a second plate and at least one third plate intermediate the first and second plates, each of the first, second and third plates comprising a current collector having an electrode active material contacted thereto with an extension portion extending from the current collector being devoid of the electrode active material, wherein the respective extension portions of the first plate, the second plate and the at least one third plate are independently electrically connected to at least three separate locations of the conductive casing to enhance heat transfer out of the cell in the event of an internal short circuit; and e) means for connecting the other of the first and second electrodes to a terminal insulated from and extending through the casing.
