electrochemical device for use in high temperature conditions. An electrochemical device, such as a battery or power source, provides improved performance under severe or extreme conditions. Such electrochemical device for use in elevated temperature conditions may include at least one cathode, a lithium based anode, a separator and an ionic liquid electrolyte. This device may also include a current collector and housing which are electrochemically inert with respect to other components of the device. This electrochemical device can operate at temperatures ranging from 0 to 180, 200, 220, 240 and 260 ° C. |
