Gold coating for a high performance Li4Ti5O12 nanorod aggregates anode in lithium-ion batteries

Solid-state synthesis and electrochemical performance of Ce-doped Li4Ti5O12 anode materials for lithium-ion batteries

“…This kind of battery draws much attention in the past decades with increasing energy demand and environmental problems caused by fossil fuels consuming. The development of LIBs in the past is based on the development of electrode materials, such as spinel LiMn 2 O 4 and their derivation materials [6][7][8], olivine phosphate [9][10][11], silicon based materials [12][13][14], Li 4 Ti 5 O 12 [15][16][17][18][19][20][21][22], besides the commonly used LiCoO 2 and graphite. Among these electrode materials, Li 4 Ti 5 O 12 has been demonstrated as one of the most promising anode materials for LIBs since it exhibits ultra-long lifetime with zero structural change during the lithium insertion/extraction process and a relatively higher operating voltage (1.55 V vs. Li/Li + ) to ensure better safety of LIBs by avoiding the formation of lithium dendrites than the graphite electrode.…”

“…To overcome the significant drawbacks of Li 4 Ti 5 O 12 , several approaches have been developed to improve the conductivity or electron transfer of Li 4 Ti 5 O 12 . One route is to synthesis nanostructure Li 4 Ti 5 O 12 materials including nanoparticles [16][17][18], nanorods [19], nanoplates [20] and so on. The nanostructures can reduce diffusion paths of both electron and lithium ions.…”

Li4Ti5O12/TiO2-SiO2 and Li4Ti5O12/SiO2 composites as an anode material for Li-ion batteries

“…In particular, by using flexible current collectors such as carbon nanotubes and fibers, flexible LTO composite electrodes have been obtained [71,86]. In addition, combining LTO with conducting metallic nanoparticles can also improve the rate performance of LTO electrodes [87][88][89][90][91][92][93][94]. These improvements are noteworthy but still insufficient for power and flexibilityoriented applications.…”

Enhanced rate performance of nanosized Li 4 Ti 5 O 12 /graphene composites as anode material by a solid state-assembly method

“…10 À9 to 10 À13 cm 2 s À1 ) of LTO degrades its electrochemical performance and hinders practical application for high current applications before any materials modifications. So far, the conductivity and rate performance of LTO have been achieved by using foreign atoms doping [4,[6][7][8][9][10][11][12][13][14], nanostructures [15][16][17] and electronically conductive coatings [18][19][20][21][22][23][24][25]. Among these methods, preparation of LTO/carbon composites by a facile route is practicable and economical for large-scale industrialization [21,26].…”
