Co-extrusion of periodically modulated structures
View Patent ↗A structure at least one stripe of material having a length, wherein a first stripe has a varying width along the length.
1. A structure, comprising:
a first longitudinal stripe of a first material containing at least one electrochemically active material on a surface, the first stripe having borders with a first continuous, periodic sinusoidal pattern of wider and narrower portions about a centerline of the first stripe, wherein the centerline is between the borders; and
a second longitudinal stripe of a second material adjacent to, and in contact with, the first stripe, the second stripe having borders with a second continuous, periodic sinusoidal pattern of wider and narrower portions about a centerline of the second stripe complementary to the first pattern, wherein the centerline is between the borders.
2. The structure of claim 1 , wherein the first material and the second material are a same material.
3. The structure of claim 1 , wherein the first material and the second material are different materials.
4. The structure of clam 1 , further comprising a third material.
5. The structure of claim 1 , wherein the second material is a non-active material.
6. The structure of claim 1 , wherein the first material is electrically conductive.
