Abstract: An electrolyte for use in an electrochemical cell. The electrolyte includes a first layer having a thickness of about 1 μm to about 40 μm and a second layer having a thickness of about 5 μm to about 60 μm. The first layer includes, based on a total weight of the first layer, about 10 wt. % to about 40 wt. % of first solid-state electrolyte particles, about 1 wt. % to about 15 wt. % of lithium, and about 1 wt. % to about 65 wt. % of fibrils including carbon and fluorine, The second layer includes second solid-state electrolyte particles.
