Self-assembled synthesis of nanoflower-like Li4Ti5O12 for ultrahigh rate lithium-ion batteries

Small amount of reduce graphene oxide modified Li4Ti5O12 nanoparticles for ultrafast high-power lithium ion battery

“…It can be seen clearly that all the circles have a couple redox peaks corresponding to the insertion and extraction of Li þ . [27] It is noteworthy that the reductive peak area of the 1st cycle is much large than others implying the existence of irreversible capacity. It is in good agreement with the cycle performance (Fig.…”

Preparation and characterization of W-doped Li4Ti5O12 anode material for enhancing the high rate performance

“…However, electrodes made from LTO without any materials modifications usually show poor rate performance, which mainly results from the poor electronic conductivity [6]. To enhance the electronic conductivity of this material, three methods were mainly proposed, including synthesis of nanosized particles [7][8][9][10][11], deposition of metal powder or carbon on LTO particle surface [12][13][14][15][16], substituting Li or Ti by doping it with metal ions (such as AI 3+ [6], Ag + [17], Na + [18], Mg 2+ [19], V 5+ [19,20], Zr 4+ [21], Ni 2+ [22], Nb 5+ [23], La 3+ [24] and Ru 4+ [25][26][27]). Doping can have a direct impact on the structure and stability of LTO during lithium intercalation and deintercalation.…”

Nitridated mesoporous Li4Ti5O12 spheres for high-rate lithium-ion batteries anode material

“…10 −9 -10 −13 cm 2 s −1 ) are relatively low and prohibitive for achieving high-rate performance [7,8]. In order to realize the high-power application, many efforts have been made to ameliorate the lithium-ion diffusion and electron transfer efficiency, including doping with foreign atoms [9][10][11], synthesizing nanostructures [12][13][14][15][16], and introducing electronically conductive coatings [17][18][19][20]. Synthesizing nanostructured LTO particles or sheets is one of the most efficient strategies to reduce the lithium-ion diffusion and electron transport pathway so as to improve their rate capability [12,13].…”
