Wire‐shaped micro‐supercapacitor and micro‐battery: Aligned multi‐walled carbon nanotube fibers and composite fibers have been easily twisted to produce both wire‐shaped supercapacitors and lithium ion batteries with high performances. The energy densities achieved 92.84 and 35.74 mWh/cm 3 while the power densities could reach 3.87 and 2.43 W/cm 3 during the charge and discharge process, respectively. The unique structure enables promising applications in various fields, e.g., these wires can be easily integrated into electronic textiles by a conventional weaving technique.
