Galvanostatic charge/discharge (GCD) profiles of the first five cycles of HTO, HTO-PA and HTO-HDA at 50 mA g -1 in standard organic electrolyte (LP30) are shown in Fig. . All three samples exhibit a pronounced plateau for the lithium intercalation reaction. The reduction plateau is located at ca. 1.7 -1.5 V for HTO and at ca. 1.5 -1.3 V for HTO-PA and HTO-HDA, demonstrating a shift to a lower lithiation potential for pillared HTOs. All three samples exhibit comparable initial coulombic efficiencies (72 -77 %) with slight performance degradation over the first five cycles (least pronounced for HTO-PA). This indicates that organic pillars do not contribute to a decrease in initial efficiency or stability compared to pristine HTO.
