The purpose of the contract was to design, develop and deliver a complete Lithium Organic Electrolyte Reserve Battery including activation mechanism to an initial specified configuration. An amendment to the scope of work was added to the contract to determine the causes for stability of a particular electrolyte formulation and also to generate material specifications that will sufficiently describe and control the important characteristics of the electrolyte and constituent materials. The choice of electrolyte was based in part on the results obtained from comprehensive studies concerning the high temperature stability of 2M LiAsF6MF electrolyte solutions. It was found that the addition of small amounts of LiBF4 to these solutions greatly increased their high temperature storage capabilities. It was determined that the LiBF4 was effective only when lithium metal was also present in the solution. LiBF4 was able to stabilize solutions prepared with grades of LiAsF6 obtained from other vendors but to a much lesser degree.
