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

“…2. Each spectrum shows five main Raman bands peaked at about 234, 348, 423, 674 and 744 in the range of 200-1000 cm À1 , representing the features of the spinel structure (A1 g + Eg +3F2u), which are similar to those of the previously reported Li 4 Ti 5 O 12 [2,38,41]. Note that these peaks intensity of LTO/graphene composites is weakening in Fig.…”

“…According to Shi et. al [38], these two bands are attributed to the D-band (K-point phonons of A1 g symmetry) and 15 30 In order to check the graphene film on the particles, the powder was analyzed by TEM. Fig.…”

“…The electrochemical impedance spectroscopies (EIS) measurement was performed by a CHI 660a electrochemical workstation, and the frequency ranged from 0.01 Hz to 100 kHz with ac signal amplitude of 5 mV. [26,38,39], no any diffraction peaks according to graphitic structure was detected, most likely because they are below the limits of detection by XRD or graphene in the LTO/graphene composite is in amorphous form.…”

“…Recently, it has been noted that the combination of Li 4 Ti 5 O 12 and graphene to fabricate LTO/graphene composite is a reasonable approach to improve high-rate capability and electrical conductivity of Li 4 Ti 5 O 12 [33][34][35][36][37]. The synthesis technologies of LTO/graphene composite such as hydrothermal route [21], sol-gel method [26], electrospinning deposition [33], solvothermal process [35], microwave-hydrothermal method [38], and solid state method [39], have been reported by many researchers. However, the soft chemistry methods mentioned above have some disadvantages, such as complicated synthetic routes and high synthetic coast, and it is difficult to commercial application.…”
