Li2Ti3O7 with the ramsdellite-type structure undergoes lithium insertion reactions with n-BuLi. Li2+xTi3O7 phases form with x = 0.5 and 1.0 at room temperature and at 50°C, respectively. The ESR spectrum of Li3Ti3O7 confirms the partial reduction of Ti4+ ions to Ti3+. The electrical conductivity of the fully lithiated phase is several orders of magnitude higher than that of the host compound, suggesting charge hopping in the mixed valent lithiated compound.
