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 (...

Ultimately, the control system will require specific ion concentration data, which would feed into a mass flux driven control algorithm that takes into account the effects of growth medium capacitance and plant uptake [83]. This combined system of ion-specific data and mass transport modelling ...
