Abstract:

An investigation into the feasibility of high energy battery based on the use of the magnesiumsulfur couple in an electrolytic solution in liq id ammoni indicated that it is possible to obtain as much as 50 watt-hours per pound of cell structure electrodes, electrolyte, and spacers at a 15-minute rate. Translation into an aut matically activated battery would probably reduce this value to less than 20 watthours per pound. There i little change in output between -40 C and 20 C. The attery could presumably be used at considerably lower and higher temperatures with nearly the same output. Whereas such a ba tery appears to be competitive with other automatically activated reserve batteries, especially for low-temperature service, it delivers about 7 of the desired output of 250 watt-hours per pound. Therefore, it is concluded that the feasibility o very high energy batteries was not demonstrated. Author
