Lithium solid electrolyte, primary cell reactions

Honeywell have described their work on the development of an alternative electrolyte for a multi-cell lithium-sulphur dioxide resen e battery. In developing a multi-cell lithium reserve battery, the lithium bromide-sulphur dioxide acetonitrile electrolyte system used in their primary batteries was found to be unstable when stored by itself at high temperature - a functional capability required for all resen e applications. In addition to consumption of the oxidant sulphur dioxide in reactions causing instability, some of the products of electrolyte degradation arc solid, which would cause nrajor problems in activation. Primary active cells after storage do not undergo such degradation reactions.
