The specific capacitance from the CV curves was calculated using the relation: ∫C = 1 2msV Vf I (V )dV Vi (10) where m is the mass of active material excluding mass of the binder (here m ~ 1 mg for all the materials in 3-electrode measurements), s voltage window range V...
Electrochemical testing results: (a) CV curves for the samples at 50 mVs À 1 scan rate; (b), (c) and (d) galvanostatic charge–discharge curves of the pH ¼ 2, 4 and HxMnO2 samples; (e) comparison of specific capacitance for the samples as a function of current density; and (...

The remnant polarization is ~15 µC cm − 2 for both BiT and BiT–LC, comparable to the previously reported values of 15.9 µC cm − 2 from a (104)-oriented La doped BiT film24. (Capacitance and dielectric loss measurements are shown in Supplementary Fig. S1 ...
