Characterization of as synthesized materials in the Li2O–TiO2–H2O ternary space. a TG analysis; b Ex situ XRD patterns and (c) contour plot of in situ HEXRD profile (red represents a high intensity and blue represents a low intensity) of LTHs-precursor heated to different temperatures. Comparison among LS, HN and DN electrode materials in the following three cases: d Charge–discharge profiles at 100 mA g−1 between 1.0 and 2.5 V (vs Li/Li+); e Rate capabilities at different current densities from 200 to 8000 mA g−1 and f cycling stability at 4000 mA g−1. All RT electrochemical measurements d–f were carried out in two-electrode 2032 coin-type half-cells
