The Lithium Thionyl Chloride Battery-A New Source for Automotive Applications 860571

LITHIUM BATTERIES ARE IMPLEMENTED IN ELECTRONIC DEVICES AND SERVE AS A BACKUP TO MEMORIES OR A MAIN POWER SOURCE IN INSTRUMENTS USED IN THE AUTOMOTIVE INDUSTRY. THE PURPOSE OF THIS PAPER IS TO INFORM THE ENGINEER ABOUT THE CHARACTERISTICS, PERFORMANCE, ADVANTAGES, LIMITATIONS, SAFETY AND GENERAL APPLICABILITY OF LITHIUM BATTERIES, AND PARTICULARLY THE LITHIUM THIONYL CHLORIDE BATTERY (LiSOCl₂). THERE ARE DETAILS PROVIDED ON APPLICATIONS FOR CONTROLLERS. SENSING, NAVIGATION, MONITORING AND OTHER DEVICES WHERE THE LiSOCl₂ BATTERY TECHNOLOGY OFFERS AN UNUSUAL COMBINATION OF OPERATING AND COST ADVANTAGES. THIS CHEMISTRY COMBINES THE HIGHEST PACKAGED DENSITY OF ANY COMMERCIALLY AVAILABLE SYSTEM WITH A WORKING VOLTAGE OF APPROXIMATELY 3.6 VOLTS, OUTSTANDING STORAGE CAPABILITY, LOW SELF-DISCHARGE RATES EVEN AT ELEVATED TEMPERATURES UP TO 85°C. AND U.L. RECOGNIZED SAFETY. ALTHOUGH THE EMPHASIS IN THIS ARTICLE IS MAINLY ON THE USE OF LiSOCl₂ BATTERIES FOR MEMORY RETENTION, IMPLEMENTATION OF THIS BATTERY TECHNOLOGY AS A PRINCIPAL POWER SOURCE WILL ALSO BE COVERED.
