Sol–gel synthesis of aluminum doped lithium titanate anode material for lithium ion batteries

Al-doped Li2ZnTi3O8 as an effective anode material for lithium-ion batteries with good rate capabilities

“…For a clear observation, the peak position variation of (1 1 1) plane is magnified and shown in Fig. 1 substituted for Ti 4+ located at (16d) sites in the Li 2 ZnTi 3 O 8 host structure [19]. Fig.…”

“…So far, a series of ions (e.g. Sn 4+ , Mg 2+ , Ru 3+ , Al 3+ , V 5+ , Sr 2+ , Nb 5+ , La 3+ , Y 3+ and Br À [13][14][15][16][17][18][19][20][21][22][23][24]) have been doped into different cathode and anode materials, which enhance electronic conductivity and improve electrochemical performance as a matter of fact. However, up to now, no investigation on the high rate performance of Al-doped Li 2 ZnTi 3 O 8 , especially in the form of Li 2 ZnTi 3Àx Al x O 8 .…”

Synthesis and characterization of nanostructured lithium titanate by simple peroxo route

“…Spinel lithium titanate has a high lithium intercalation voltage of 1.55 V against a lithium electrode with a theoretical capacity of 170 mAh g -1 and an actual discharge capacity of over 160 mAh g -1 [34]. The lithium titanate is prepared by several methods such as hydrothermal [35], electrospinning [36,37] sol-gel process [38,39], spray pyrolysis, microwave synthesis [40][41][42][43][44], solid state reaction [45][46][47], solvothermal process and computational methods. In this paper, we report a simple method to prepare lithium titanate by solution growth technique.…”

In-situ synthesis of nano-Li4Ti5O12/C composite as an anode material for Li-ion batteries

“…Unfortunately, the low electronic conductivity of Li 4 Ti 5 O 12 has been a main obstacle to its application [9]. Some strategies including synthesizing the nanosized particles via various methods [13][14][15], surface modification by means of conductive matters (Au, Ag, Cu, carbon, etc) [16][17][18][19] and cation doping (Na + [20], Ni 2+ [21], Zn 2+ [22], Al 3+ [23], W 6+ [24], Sr 2+ [25]) in Li and Ti sites have been proposed to address this issue.…”
