FIBER • THREE LAYOUTS

Wires that store energy

Two electrode fibers side by side, coated in a gel electrolyte

Two fibers wound around each other like a rope, gel electrolyte between

A core fiber electrode, an electrolyte sheath, and an outer electrode, like a coaxial cable

Fibers are the one-dimensional end of the geometry spectrum: length becomes the scaling axis.

FIBER • STRENGTHS AND CATCHES

Weavable, but resistive

Strength Thin and flexible; can be woven, knitted, or embroidered into fabric

Catch: resistance R = ρL/A grows with length, so long fibers lose power

Catch: capacity Little electrode area per length, so modest storage

Materials Carbon nanotube yarn, graphene fiber, carbon fiber, coated metal wire

A textile of many short fiber cells in parallel often beats one very long fiber.
