The electrochemical Li + intercalation properties were evaluated in organic electrolyte as a function of the nanoconfinement properties of the HTO host materials. It was found that interlayer expansion by molecular pillars results in an increased maximum Li + storage capacity from ca. 2.1 Li + per tetratitanate in pristine HTO to ca. 2.95 Li + per tetratitanate in HTO-PA.
