High Energy Density Pelletized Aluminum Chlorine Thermal Batteries.
Abstract
The Eureka Advance Science Corporation entered into a contract to engineer the development of a thermal battery based upon an electrochemical cell developed at the Frank J. Seiler Research Laboratory. This cell utilizes aluminum or lithium-aluminum alloy as its anode, a Cab-O-Sil/NaAlCl4 mixture as anolyte, and a mixture of anolyte, MoCl5 and graphite as cathode. Engineering research at the Eureka Advance Science Corporation was undertaken to develop a profile of the operating characteristics of a battery utilizing this cell, and to investigate the feasibility of manufacturing such a battery. Commercially available NaAlCl4 was found to be unsuitable for cell preparation. The synthesis of NaAlCl4 was carried out at FJSRL and at Eureka, and both synthesized materials were found satisfactory for the production of anolyte and catholyte. Lithium-aluminum alloys of 20 w/o Li and 28 w/o Li were investigated, and both were found to be suitable anode materials.
