An investigation of the most direct and systematic approach in selecting the most promising materials for the development of higher capacity secondary batteries for space applications is reported. The experimental approach, materials, and necessary precautions required in molten salt technology are summarized. Advantages and disadvantages of the various molten salt elec trolytes considered are presented. Experimental procedures and couple materials investigated are discussed. The experimental results for the molten- salt cells investigated are presented. Data are presented for cells with fluoride, chloride and sulfate molten-salt electrolyte. Objectives and results of a ceramic separator study phase of the program are included. The design of a molten-salt secondary battery which was constructed during the course of the program is described, along with fabrication procedures of this battery. Theoretical calculation for the initial heat input versus heat output and the heat loss due to cell radiation is presented.
