Abstract : The report describes research on inorganic compounds for use as positive electrodes in a rechargeable lithium battery. First, desired characteristics of the candidate electrode materials were considered, including theoretical voltages and idealized weight relationships and, therefore, the maximum watt hours per pound that could be expected. Two dozen separate compounds were considered in this preliminary analysis from among seven general classes of inorganic compounds that included the metal salts of carbonates, cyanides, cyanates, thiocyanates, hydroxides, sulfides, and methoxides. Second, electrolytes to be used in combination with the candidate electrode compound were developed. One prerequisite for rechargeability in the electrolyte development was the presence of an anion common to both the positive electrode compound and to the electrolyte solute. An electrolyte resistivity lower than 1000 ohm-cm also was sought in these studies as well as stability of the electrolyte with the positive electrode compound and with lithium. (Author)
