Non-Aqueous Magnesium Batteries. Phase 1

摘要

The Phase I research aimed at developing nonaqueous magnesium batteries has ledto the identification of several electrolytic solutions. They include Mg(ClO4)2 in propylene carbonate (PC), LiAsF6 in PC, and LiAlCl4.2.6SO2, with conductivities of 0.0044/, 0.0051/, and 0.072/ohm.cm, respectively. Because Mg is more electronegative than Li, solutions of Li salts can be used in Mg primary batteries. The Mg/CuF2 cell, utilizing the LiAlCl4.2.6SO2 electrolyte, and the MgSO2,C cell have been identified as useful electrochemical power sources, as determined by the extent of their discharge capacities. Potential commercial applications of high energy density magnesium batteries include communication devices, hand-held tools, toys, military and space equipment, and biomedical devices.
