Strongly Coupled NiCo2O4 Nanocrystal/MXene Hybrid through In Situ Ni/Co–F Bonds for Efficient Wearable Zn–Air Batteries

; to the best of our knowledge, this is the record performance among all reported flexible ZABs with MXene-based air cathodes and comparable with some noble metal catalysts. Moreover, even after cutting and suturing, our flexible solid-state ZAB devices are tailorable with high rate of performance.
