ABSTRACT:
A method of assembling a lithium alloy/molten salt/metal chalocogenide, high-energy density electrochemical device. Broadly, the method comprises providing a negative electrode structure in intimate contact with an electrolyte, which is conductive at elevated temperatures. There also is provided in contact with the electrolyte a positive electrode structure which includes a current-collecting substrate containing a sulfur and oxygen compound of at least one alkali metal in intimate admixture with a particulate metal. An electric current is passed from one electrode to the other to cause such device to be in a desired state of elecrochemical charge, whereby when said device is in a charged state a negative electrode active material comprises an alkali metal alloy and the positive electrode active material comprises a mixture of oxides and sulfides of the particulate metal.
