Lithium chlorate, , has reported melting points of 127.6° and 129°C. The specific conductance of molten lithium chlorate at 130°C is relatively high compared to common aqueous electrolytic solutions at room temperature. Therefore, lithium chlorate offers the chance to operate a new lithium battery system at a temperature between 130° and 150°C. It was found experimentally that lithium chlorate is stable in the potential range between 3.2 and 4.6V relative to an Li reference electrode. An secondary battery system was observed to have an open‐circuit potential of 3.97V, making an secondary battery in molten lithium chlorate possible, in principle. A lithium‐lithium chlorate primary battery system is also possible. Lithium negative electrode performance was found to be hindered by corrosion and possible runaway reactions with . Dendrite formation on charging was observed. The solubility of and in at 145°C is , respectively. The diffusion coefficients are for and for . Platinum appeared to be an inert positive electrode for chlorate, chlorine, or oxygen reactions for runs on the order of several hours. Nickel shows an active‐passive behavior which is complex. Nickel appears suitable for use in a primary cell for the cathodic discharge of , but it does not appear suitable for a or electrode.
