Cyclic voltammograms (CVs) at a rate of 10 mV/s give additional insights into the (de)lithiation process (Fig. ). While all (cathodic) lithiation peaks are roughly centered at around 2.6-2.7 V vs. Li + /Li, the peak shapes become broader with increasing V2O5 interlayer spacing. Quantitative analysis of the capacity at different currents is probed by GCD at rates up to 5 A/g (Fig. ). The trends of improved kinetics for larger interlayer spacings are reflected in the capacity retention at higher rates, with V2O5-12C-DA showing the highest capacity retention of 50 mAh/g compared to 37 mAh/g (V2O5-6C-DA) and 23 mAh/g (V2O5-2C-DA) at a rate of 5 A/g. It should be noted that the reported values of specific capacity take into account the mass of both the V2O5 host and the alkyldiamine pillars, where the latter do not contribute to the reversible charge storage process. Thus, to gain fundamental insights into the charge storage process in pillared V2O5 hosts, quantification of stored Li + per structural unit of V2O5 is derived from the reversible, electrochemically stored charge and the quantity of pillars derived from TGA. Calculation of the maximum number of Li + stored yields stoichiometries of Li1.02V2O5, Li1.27V2O5-2C-DA, Li1.48V2O5-6C-DA, and Li1.33V2O5-C12-DA, demonstrating increased storage capacity of pillared V2O5 despite the additional presence of pillar molecules in the interlayer space.
