“…As a promising anode material for Li-ion batteries (LIBs), MLi 2 Ti 6 O 14 (MLTO, M = 2 Na, Sr, Ca, Ba and Pb) has been investigated with a focus on enhancement of its electrochemical performance for MLTOs containing single M species [3][4][5][6][7][8][9][10][11]. Previous studies have revealed that all of the MLTOs are constructed upon the same TiO 6 octahedral arrangements, which suggests the possibility of MLTO's preparation with two or more M species in the same material.…”

A simple stoichiometric modulation of Na 2−2x Sr x Li 2 Ti 6 O 14 was developed to achieve tunable electrochemical properties of the material. The concept was confirmed experimentally and theoretically using density functional theory (DFT) calculations. Both the operating potential and the amount of reversibly intercalated lithium ions were manipulated by simply changing the Na/Sr ratio. These unique characteristics originated from a gradual change in the electron density on the Ti atoms and the extra lithium insertion sites at SrLi 2 Ti 6 O 14 . As a promising anode material for lithium-ion batteries, Na 2−2x Sr x Li 2 Ti 6 O 14 and its tunable electrochemical properties have significant importance in terms of the development of tailored electrodes with desirable electrochemical performance.
