Synthesis process investigation and electrochemical performance characterization of SrLi2Ti6O14 by ex situ XRD

Ultralong SrLi2Ti6O14 nanowires composed of single-crystalline nanoparticles: Promising candidates for high-power lithium ions batteries

“…Between the two materials, SrLi 2 Ti 6 O 14 with theoretical capacity of 262 mA h g À 1 exhibited better promising properties. SrLi 2 Ti 6 O 14 possesses a three-dimensional (3D) structure with the Cmca space group that enables the lithium ions quickly migrate, resulting in excellent high power performance [22,23]. Recently, nanostructured materials appears to be interesting, as it owns a short Li ion insertion/extraction distance, facile strain relaxation upon electrochemical cycling, and very large surface to volume ratio to contact with the electrolyte, which can improve the capacity and cycle life of LIBs [24][25][26][27].…”

Lithiation and delithiation behavior of sodium lithium titanate anode

“…Recently, Ti-based materials attract extensively concerns for the successful commercialization of Li 4 Ti 5 O 12 [9][10][11][12][13][14][15][16][17][18], which maintains the stable structure during long-term charge-discharge process. Besides, the high electrochemical motivation force (1.55 V vs. Li/ Li + ) of Li 4 [19][20][21][22][23][24] and MLi 2 Ti 6 O 14 (M = Ba, Sr, Pb, 2Na) [25][26][27][28][29][30][31] were successfully synthesized and used as anode materials for lithiumion batteries. It can be concluded that the Li 2 MTi 3 O 8 (M = Zn, Co, Mg, Mn) possesses excellent structural stability during lithiation/ delithiation process.…”

“…Besides, the lithium-ion insertion/extraction mechanism of Li 2 MnTi 3 O 8 has been also studied in detail recently [20]. At the same time, MLi 2 Ti 6 O 14 (M = Ba, Sr, 2Na) with stable structure was reported as potential lithium storage material [25][26][27][28][29][30][31]. Moreover, it is reported that the BaLi 2 Ti 6 O 14 obtains the reversible capacity of 137.7 mAh g À1 at a current density of 50 mA g À1 with the capacity retention of 94.51%.…”

Structure and electrochemical performance of BaLi2−x Na x Ti6O14 (0≤x≤2) as anode materials for lithium-ion battery

“…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.…”
