A directly grown pristine Cu-CAT metal-organic framework as an anode material for high-energy sodium-ion capacitors

Chem Commun (Camb). 2019 Sep 17;55(75):11207-11210. doi: 10.1039/c9cc06048k.

Abstract

Copper-based metal-organic framework (Cu-CAT) nanowires are directly grown as an anode of sodium ion hybrid capacitors (SIHCs) for the first time. The uniform molecular pores provide a natural Na+ diffusion pathway and abundant accommodations for Na+ coordination to the C-O active sites, which greatly facilitate the kinetics balance with the capacitive cathode and boost the energy density of SIHCs, respectively.
