Development of a low-melting-point eutectic salt and evaluation of its discharge performance for light weight thermal batteries.

ABSTRACT

This paper proposes low-melting-point eutectic salts containing RbCl as electrolytes for light weight thermal batteries. The handleability of the eutectic salts was remarkably improved for commercialisation. Their performance as thermal battery molten-salt electrolytes was verified using tests on a single cell and a 12-cell stacked battery.
