“…Among them, spinel Li 4 Ti 5 O 12 was viewed as one promising alternative to carbonous materials due to its small dimensional change during cycling and high insertion potential (1.55 V, versus Li/Li + ) [8][9][10]. Despite the great significance of Li 4 Ti 5 O 12 as a famous lithium storage material, a new series of Ti-based compounds, MLi 2 Ti 6 O 14 (M = 2Na, Sr, Ba), were proposed as host materials in LIBs [11][12][13][14][15][16][17][18]. Among them, only few researches on the electrochemical performance of BaLi 2 Ti 6 O 14 were reported.…”
