Construction of triple-layered sandwich nanotubes of carbon@mesoporous TiO2 nanocrystalline@carbon as high-performance anode materials for lithium-ion batteries

A uniform few-layered carbon coating derived from self-assembled carboxylate monolayers capable of promoting the rate properties and durability of commercial TiO2

“…The performance of TiO 2 /C-30 was also compared with other modied TiO 2 in literature ( Table 2). With respect to the highly pure TiO 2 derived from tetraethyl orthotitanate, 27 tetra-n-butyl titanate, 28 titanium isopropoxide 29,30 as well as modied by other carbon materials, TiO 2 /C-30 reveals the performance comparable to that in the literature despite the simply fabrication of TiO 2 /C-30 by employing the cheap raw materials of c-TiO 2 and CA.…”

Spontaneous redox reaction-mediated interfacial charge transfer in titanium dioxide/graphene oxide nanoanodes for rapid and durable lithium storage

“…The lithium storage performance of the optimal sample (GTiO 2 -1 M) is also compared with other TiO 2 -based electrodes, as presented in Table 2. It was found that the GTiO 2 -1 M anode material demonstrates the best electrochemical performance, including outstanding capacity, excellent rate performance, and stability than the TiO 2 anodes with dedicated composites, morphologies, or architectures, such as walnut-like porous core/shell TiO 2 with hybridized phases, 32 surface-amorphized TiO 2 anchored on graphene, 33 3D TiO 2 nanowires/rGO composites, 39 ultralong mischcrystal TiO 2 nanowires and rGO, 44 3D graphene-supported ultrafine TiO 2 nanorod, 47 nitrogen-rich carbon-coated TiO 2 particles, 48 MXene-derived TiO 2 /rGO composites, 49 carbon@mesoporous TiO 2 nanocrystalline@carbon, 50 and (001) faceted nanosheet-constructed hierarchically porous TiO 2 /rGO composite. 51…”

Enhancing capacity and transport kinetics of C@TiO2 core–shell composite anode by phase interface engineering

“…For instances, Kim and coworkers synthesized carbon coated anatase titania and reported a stable discharge capacity of 100 mAh g −1 at 9.9 A g −1 charge/discharge current density [18]. A triplelayered C@mesoporous-TiO 2 @C sandwich nanotube exhibited a specific capacity of 244 mAh g −1 and a watermelon-like TiO 2 @C structure presented a specific capacity of 312 mAh g −1 at a current density of 170 mA g −1 [19,20]. These outstanding electrochemical performances compared to individual C and TiO 2 was usually ascribed to the synergistic effect of the two comprising components [18][19][20][21][22][23].…”

Indeed, in a composite structure, besides the synergistic effect that takes advantages of the merits of each component, the phase interface effect should never be neglected, particularly in a nanocomposite system where the particle size is nanoscale and so that the phase interface claims a high specific weight.…”
