[0004] 2. Description of the Related Art

[0005] Lithium batteries typically have high voltage and high energy densities, and thus are used in various applications. Devices such as electric vehicles, e.g., a hybrid electric vehicle (“HEV”), plug-in hybrid electric vehicle (“PHEV”) and the like, are desired to be operable at high temperatures, to charge or discharge a large quantity of electricity, and to have long-term usability, such that such devices use lithium batteries ha...
