Abstract

Described herein are, among other things, structured cathodes for use in electrochemical cells (e.g., batteries). In some embodiments, a structured cathode includes at least one electrochemically active material included in a patterned film. The film may be disposed on a substrate (e.g., current collector) or may be free standing. The film has at least one patterned surface, for example has recesses extending into the film. A patterned film may be porous. A patterned film may be made of an assembly of particles including an electrochemically active material. Recesses may include holes or trenches or a combination thereof. Recesses may be formed by removing material from an initial film, such as with laser ablation. Recesses may extend only partially into or entirely through a film. Recesses may be interconnected or separate. Recesses may be disposed regularly or irregularly across a patterned surface. Recesses may be at least partially filled with electrolyte.
