The relationship between structure and lithium storage capacity of different titanate samples as anode materials for lithium-ion batteries is discussed. Li₄Ti₅O₁₂, Na₂Ti₃O₇ and Na₂Ti₆O₁₃ were synthesized by solid-state reaction. The structure, surface and morphology of the samples were characterized by SEM, XRD and RAMAN spectroscopy. The electrochemical performance was studied by galvanostatic charge-discharge cycling, cyclic voltammetry, electrochemical impedance spectroscopy and rate capability. The lithium titanate presented the highest capacity of the three electrodes, together with the most reversible potential plateau at 1.6 V vs. Li⁺/Li⁰ and the best response in rate capability. Apparent diffusion coefficients of Li⁺ ions into the titanate matrices were obtained, showing the highest value for the lithium titanate compound. Between both sodium titanates, Na₂Ti₆O₁₃ presented the highest specific capacity and the best discharge retention
