Variable pressure insulating jackets for high-temperature batteries
A new method is proposed for controlling the temperature of high-temperature batteries namely, varying the hydrogen pressure inside of multifoil insulation by varying the temperature of a reversible hydrogen getter. Calculations showed that the rate of heat loss through 1.5 cm of multifoil insulation between a hot-side temperature of 425[degrees]C and a cold-side temperature of 25[degrees]C could be varied between 17.6 W/m[sup 2] and 7,000 W/m[sup 2]. This change in heat transfer rate can be achieved by varying the hydrogen pressure between 1.0 Pa and 1,000 Pa, which can be done with an available hydrogen gettering alloy operating in the range of 50[degrees]C to 250[degrees]C. This approach to battery cooling requires cylindrical insulating jackets, which are best suited for bipolar batteries having round cells approximately 10 to 18 cm in diameter.
