NOVELTY - The battery (110) has a positive terminal (126) for operating the battery at a first level of a first internal resistor over temperature range of the battery between first temperature and second temperature. A high resistance negative terminal (122) is adapted for operating the battery at a second level of a second internal resistor outside of the first temperature and the second temperature. A self-activated switch (124) activates the second internal resistor when the temperature of the battery is about the second temperature. A resistor sheet acts as a heating element.    USE - Rechargeable battery such as nickel-metal hydride battery and lithium ion battery, for a battery system (all claimed), used in transportation application i.e. vehicles, aerospace application, military application and stationary energy storage application such as grid energy storage and outdoor power backup systems. Can also be used for a lithium-polymer battery, a lead-acid battery, a nickel-manganese-cobalt battery, a lithium-sulfur battery, a lithium-air battery and all solid-state battery.    ADVANTAGE - The battery can exhibit high resistance for generating heat internally to warm up the battery quickly. The battery reaches normal operating temperatures and can be switched to a low resistance operating mode, thus delivering ultra-power and energy operating in low ambient temperature. The battery can amplify internal heating within battery cells at low ambient temperatures, so that electrochemical and transport processes controlling battery performance can be effectively improved.    DETAILED DESCRIPTION - The high resistor terminal is an additional negative terminal and an additional positive terminal. The switch is selected from one of an electromechanical relay and a temperature controller or a solid-state relay with a temperature sensor, a power MOSFET with a temperature sensor and a high-current switch with a temperature sensor. An INDEPENDENT CLAIM is also included for a method for operating a rechargeable battery.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an all-climate battery including resistor sheets/foils embedded within a stack of electrode-separator assemblies, a high-resistance negative terminal and a low-resistance negative terminal, a positive terminal and a thermally activated switch connecting the high-resistance negative terminal and the low-resistance negative terminal.
