✦ Synopsis

Lithium-manganese dioxide cells have not only excellent specific energy and shelf life characteristics, but they are also capable of very promising performance at temperatures as low as --40 °C (--40 OF). The polarization and discharge curves of cylindrical and button cells at --40 °C are compared in an effort to evaluate the useful low temperature operation range. The cathode design, and type of MnO2 strongly affect the low temperature behaviour. Although the excellent low temperature performance of the Li/SO 2 system can probably never be equalled, due to some diffusion shortcomings inherent in the Li/MnO2 cells, for low and moderate current drains covering many meteorological, military, and consumer applications, Li/MnO2 batteries are very competitive in terms of simple technology, increased safety, and price, offering satisfactory operation within the range --40 to +71 °C (--40 °F to +160 °F).
