Abstract: A lithium metal electrode comprises a layer of lithium metal coating a conductive substrate, the layer of lithium metal having no more than five ppm of non-metallic elements by mass. The layer of lithium metal is in turn coated with a lithium ion conductive conformable polymer, thereby providing the negative electrode and the solid electrolyte for a rechargeable lithium metal battery that further includes a positive electrode. Optionally, the positive electrode includes elemental sulfur in a conductive matrix. The conformable polymer coated lithium metal electrode may be manufactured by a process involving electroplating lithium metal through a conformable polymer coated conductive substrate, for which the conformable polymer coated conductive substrate has been prepared by coating the conductive substrate in a solution of the conformable polymer followed by evaporating the solvent. Alternatively, a lithium metal electrode may be coated directly with conformable polymer.

Alternatively, a lithium metal electrode may be coated directly with copolymer. Rechargeable lithium batteries according to embodiments of the invention have improved cycle life and combustion resistance compared to lithium metal batteries manufactured by conventional methods.

The electrolysis is performed under a blanketing atmosphere, the blanketing atmosphere being substantially free of lithium reactive components. Methods are further proposed for vertically integrating the electrolytic fabrication of highly pure lithium metal electrodes into the production of lithium metal batteries, the fabrication of lithium electrodes and lithium metal batteries being performed in a single facility.
