Electrochemical Intercalation of Lithium into Transition Metal Compounds in Low Temperature Chloroaluminate Melts

Investigation of the electrochemical intercalation of lithium into several high oxidation‐state transition metal compounds (, , , and ) has been undertaken in low temperature chloroaluminate melts: at 60°C and at 175°C. The reversibility of the different steps of intercalation and deintercalation has been examinated. Cycling tests have shown a good stability and capacity of and in these molten salt media.
