Patent ID: 8003241

Claim:
A lithium-ion battery, comprising: a) a first terminal in electrical communication with a first electrode of the battery; b) a second terminal in electrical communication with a second electrode of the battery; c) a cell casing that includes a lid, wherein the lid is in electrical communication with the cell casing and the cell casing is electrically insulated from the first terminal and in electrical communication with the second terminal; d) a positive thermal coefficient layer, having an increasing electrical resistivity with increasing temperature, in electrical communication with the first terminal of the battery and over the lid of the cell casing; e) a first conductive layer over the lid of the cell casing; f) a second conductive layer, wherein at least a portion of the second conductive layer is at least a component of the first terminal, or is electrically connected to the first terminal; g) a feed-through device electrically connecting the first electrode of the battery to the first terminal; and wherein the positive thermal coefficient layer is between the first and second conductive layers, the first conductive layer is physically connected to the feed-through device, and is over the feed-through device, and each of the lid of the cell casing, the second conductive layer and the positive thermal coefficient layer defines a pass-through hole through which the feed-through device is connected to the first conductive layer.
