A new solid-state electrolyte system to pair with high-capacity lithium anodes and metal oxide cathodes is necessary for high-voltage batteries to meet higher energy density and safety targets. To overcome the challenges in existing solid-state lithium-ion batteries Oceanit investigated an innovative layer-by-layer approach to create SSLIB, with reduced interfacial resistance, and improved conductivity of Li+ ions between cathode and anode with highly conductive solid-state electrolyte. Oceanit investigated a composite LLZO-based electrolyte for high-voltage enhanced energy density batteries. Composite ceramic electrolyte with LLZO were fabricated via 3D direct-ink-writing (DIW) technique. Composite ceramic electrolytes were assembled in a coin cell format (CR 2032) with a lithium metal anode and Lithium Manganese Oxide (LMO) or Lithium Manganese Nickel Oxide cathode. Cycling studies demonstrated consistent discharge capacities for the ceramic electrolyte and when combined with LMNO, a voltage of 4.5V was achieved. The ceramic electrolyte was tested for at least 100 cycles with a minimal drop (
