The report presents a feasibility analysis of an internal cooling technique for pile-type batteries. A first-order thermal analysis is done for a battery design which uses internal heat sinks placed directly between the battery cell stacks. The heat sink contains a phase-change material and is specifically designed to permit a continuous electrical current path between cell stacks in the pile. A more accurate solution higher order may be attempted if experiment indicates the current results are inadequate. The problems of fabricating such cooling devices are not addressed here but an analysis of their performance is. The equations derived are not difficult to use in designing the cooling devices. This cooling technique is attractive for high current density pile-type batteries, particularly where an external heat sink approach is not wanted. Author
