Thermal Battery Systems for Ordnance Fuzing

Abstract

Thermal battery technology for ordnance fuzing is reviewed. Most present thermal batteries use the Ca/LiCl-KCl eutectic/CaCrO4 system. This system is highly reliable when properly fabricated, but is subject to electrical short circuiting from CaLi2 formed during operation and is capacity and rate limited by anodic film formation. Proposed replacement electrochemical systems use lithium or its alloys as anodes to eliminate these difficulties, but the high chemical reactivity of lithium causes storage and handling problems. Anodes of calcium alloys might eliminate short circuiting and increase electrical output above that of the Ca/LiCl-KCl eutectic/CaCrO4 system without causing the handling and storage difficulties of the lithium systems. The calcium alloy anode should be researched to determine its capabilities in practical batteries.
