With 1 M NEt4BF4/ACN electrolyte, cyclic voltammetry (CV) experiments at a scan rate of 10 mV s -1 showed quasi-rectangular traces and confirmed a stable double-layer voltage window of ca. 1 V for all samples of Cu3(HHTP)2, consistent with our previous work for this layered framework (Fig. ). However, voltammograms from B-CuHHTP and C-CuHHTP exhibited consistently smaller areas, indicating lower charge storage on this timescale for samples with either 'rod-like' or strongly agglomerated particles relative to those with weakly agglomerated 'flake-like' particles. Galvanostatic charge-discharge (GCD) experiments between 0 -1 V at a range of current densities further probed the performances of the three samples.
