Flexible, wearable, and portable energy storage devices with high-energy density are crucial for next-generation electronics. However, the current battery technologies such as lithium ion batteries have limited theoretical energy density. Additionally, battery materials with small scale and high flexibility which could endure the large surface stress are highly required. In this study, a yarn-based 1D Zn-air battery is designed, which employs atomic layer thin Co3O4 nanosheets as the oxygen reduction reaction/oxygen evolution reaction catalyst. The ultrathin nanosheets are synthesized by a high-yield and facile chemical method and show a thickness of only 1.6 nm, corresponding to few atomic layers. The 1D Zn-air battery shows high cycling stability and high rate capability. The battery is successfully knitted into clothes and it shows high stability during the large deformation and knotting conditions.
