# Scalable production of high-performing fiber lithium-ion batteries

Researchers from Fudan University published a study in the journal Nature suggesting how the internal resistance of high-performing woven lithium-ion fiber changes with their lengths, which provides theoretical support for developing secure lithium-ion fiber batteries.

Based on the findings, Chinese scientists have realized the scalable production of high-performing woven lithium-ion fiber batteries, bringing the wireless charging of electronics via clothes one step closer to reality.
