Effect of Sn-doping on the electrochemical behaviour of TiO2 nanotubes as potential negative electrode materials for 3D Li-ion micro batteries

Self‐Organised TiO2 Nanotubes for 2D or 3D Li‐Ion Microbatteries

“…The outstanding performance was demonstrated to be related to the rutile‐type structure, and the enhanced lithium diffusivity; Li + diffusion coefficients were estimated to be 1.6×10 −13 and 6.7×10 −12 cm 2 s −1 for TiO 2 nts and Ti 1− x Sn x O 2 nts, respectively 142b. The Li + diffusion coefficient for the TiO 2 nts was very comparable to those previously obtained for other TiO 2 materials 40b.…”

High Areal Energy 3D‐Interdigitated Micro‐Supercapacitors in Aqueous and Ionic Liquid Electrolytes

“…Even if “mW h cm −3 ” is widely used to compare the volumetric energy in the literature, such a unit appears ambiguous, except to report on outstanding figures whenever very thin electrodes are used . Consequently, such a metric was not used in this paper, and the performance was expressed in µW h cm −2 µm −1 unit as it was also reported in other papers dealing with millimeter‐scale power sources. In such a case, the thickness of the electrode is taken into account for the calculation of volumetric energy.…”

Controllable synthesis of MoO3-deposited TiO2 nanotubes with enhanced lithium-ion intercalation performance

“…Three primary methods have been proposed to deal with this problem. The first one is to dope TiO 2 nanotubes with metal or nonmetal elements, such as Sn [21], C [22] and N [23]. The second one is to coat them with conductive reagents, such as Sn [24], Ni [25] and Ag [26].…”
