Abstract

Articles and methods including layers for protection of electrodes in electrochemical cells are provided. As described herein, a layer, such as a protective layer for an electrode, may comprise a plurality of particles (e.g., crystalline inorganic particles, amorphous inorganic particles). In some embodiments, at least a portion of the plurality of particles (e.g., inorganic particles) are fused to one another. For instance, in some embodiments, the layer may be formed by aerosol deposition or another suitable process that involves subjecting the particles to a relatively high velocity such that fusion of particles occurs during deposition. In some embodiments, the layer (e.g., the layer comprising a plurality of particles) is an ion-conducting layer.
