NOVELTY - The device (110) has a component within a housing (112) to generate electric power by combining with other components, chemicals, or material residing within the housing. A thermal conductivity material with K-value of less than 400W/(masteriskK) is coupled to an interior wall surface (114) of the housing or internal components of the housing.    USE - Electrical energy storage device e.g. battery such as lithium-based battery, lithium battery, lithium-ion nanophosphate battery, lithium sulfur battery, or lithium-ion polymer-battery (all claimed) and fuel cell used in e.g. mobile device such as laptop computer. Can also be used in computer, mobile device, global positioning system (GPS) unit, power tool, electric vehicle, hybrid electric vehicle, vehicles such as truck, boat, bus, train, air conveyance such as airplane, rocket, hovercraft, helicopter, ground conveyance such as car, truck, locomotive, tank, armored personnel carrier, building such as home, warehouse, office, appliance such as refrigerator, washing machine, dryer, communication system such as networked system, telephone system, voice over internet protocol (IP) system, etc.    ADVANTAGE - The electrical storage device is cooled before the anticipation of heat generating event so that the cooling demands is kept up the thermal control system.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) method of altering temperature of electrical storage device or electrochemical energy generation device;    (2) method of operating electrical storage device or electrochemical energy generation device;    (3) method of providing power from electrical storage device or electrochemical energy generation device;    (4) method of charging electrical energy storage device;    (5) electrical storage device or electrochemical energy generation device temperature altering system; and    (6) method of thermal control of electrical storage device or electrochemical energy generation device.
