Temperature control in thermal batteries
Abstract
Methods of temperature control in thermal batteries are described. Different insulating materials are reviewed and the use of metal wraps round the cell stack to act as heat sinks is described. Salt mixtures which undergo phase changes at the operating temperatures of thermal batteries can be used as heat stores. Pyrotechnics with different burning speeds can be chosen to control the rate of heating of thermal batteries.
