Sequential deposition synthesis (SDS) is a recently-discovered technique that allows a solid-state electrolyte layer to be fabricated directly from a liquid precursor which is then atomized onto a heated substrate where the solvent evaporates and the precursor salts decompose to form a conformal layer. Li7La3Zr2O12 (LLZO) is a promising material that has seen much interest in the battery field but has challenges to synthesize this layer between 5-15 µm thick which SDS is capable of fabricating. LLZO films were fabricated directly onto a porous substrate that was infiltrated with a polymer gel electrolyte and the cycling performance was demonstrated in a full cell using Li metal anode and lithium cobalt oxide (LCO) cathode. The cycling performance is discussed in reference to state-of-the-art performance in the battery field and post-mortem analysis on the cells is performed to elucidate failure mechanisms.
