In a new study, North Carolina State University researchers made a cathode, or the positive end of a battery, in the shape of a thread-like fiber. The researchers were then able to use the fiber to create a zinc-ion battery prototype that could power a wrist watch.
Published in the journal ACS Applied Materials and Interfaces, the proof-of-concept study is a step forward in the development of a fiber-shaped battery that could ultimately be integrated into garments.
