Articles and methods are provided that include layers for protection of electrodes in electrochemical cells. As described herein, a layer such as a protective layer for an electrode may comprise a plurality of particles (eg, crystalline inorganic particles, amorphous inorganic particles). In some aspects, at least a portion of the plurality of particles (eg, inorganic particles) are fused to one another. For example, in some embodiments, the layer may be formed by an aerosol deposition method; or any other suitable method including relatively high velocity of the particles such that fusion of the particles occurs during deposition. . In some cases, the protective layer may be porous. |
