What this paper is about
Milkweed floss was carbonized with sulfur to make microtube-shaped porous carbon, then used as the cathode in lithium-sulfur batteries.
The hollow structure of the fiber survives carbonization, which is what makes it useful here. Materials science rather than biology.

Abstract
Microtube-like porous carbon (MPC) and tube-like porous carbon-sulfur (MPC-S) composites were synthesized by carbonizing milkweed pappus with sulfur, and they were used as cathodes for lithium-sulfur batteries. The morphology and uniformity of these materials were characterized using X-ray powder diffraction, Raman spectroscopy, scanning electron microscopy, transmission electron microscopy with an energy-dispersive X-ray analyzer, thermogravimetric analysis, and X-ray photoelectron spectrometry. The electrochemical performance of the MPC-S cathodes was measured using the charge/discharge cycling performance, C rate, and AC impedance. The composite cathodes with 93.8 wt.% sulfur exhibited a stable specific capacity of 743 mAh g-1 after 200 cycles at a 0.5 C.
