Abstract :
The storage temperature for typical lithium carbon-monofluoride cells ranges from -40° to +60°C. A design of the lithium carbon-monofluoride coil cell system has been optimized for high temperature (125°C) applications. The development process of the ultrahigh temperature cell focused on four basic elements of cell design: grommet; sealant; separator; and electrolyte. This cell design can also meet performance requirements after exposure to a surface mount soldering temperature profile. The optimization was accomplished utilizing the standard JR 1225 cell size as a test vehicle. An unique electrolyte formulation and polymeric seal material have resulted in cells that tolerate temperatures up to 125°C for a year without substantial degradation in performance
