Synthesis of sandwich-like TiO2@C composite hollow spheres with high rate capability and stability for lithium-ion batteries

TiO 2 /carbon hollow spheres as anode materials for advanced sodium ion batteries

“…3) The peaks between 100 and 700 cm -1 in the Raman spectrum are the typical features of anatase TiO 2 . [29] The characteristic peak located at 1347 cm -1 in the Raman spectrum corresponds to the D band of carbon, suggesting the disordered carbon. The peak at 1598 cm -1 corresponds to G band of carbon, indicating the existence of sp 2 graphitic carbon.…”

Size‐Tunable Olive‐Like Anatase TiO2 Coated with Carbon as Superior Anode for Sodium‐Ion Batteries

“…It is notable that carbon‐coating method holds the superiorities of achieving high conductivity for TiO 2 /carbon composites with a small quantity of less‐costly carbon layer by conformably wrapping on TiO 2 , rather than the relatively poor interfacial compatibility for the TiO 2 loaded on CNTs or graphene scaffolds of larger amount proportions and higher cost. However, in most cases, two or more steps are involved in the carbon‐coating routes, for example, to further deposit carbon onto the as‐prepared titania precursors to obtain the well‐coated TiO 2 , which are generally complicated and tedious, thus could hardly suit the scaled‐up practical productions.…”

Template-assisted synthesis of multi-shelled carbon hollow spheres with an ultralarge pore volume as anode materials in Li-ion batteries

“…3d). 35 According to thermogravimetric analysis (TGA) of pristine silica templates (MSHS and DMSHS) and intermediates (CSCHS and DCSCHS), the carbon content in the intermediate CSCHS and DCSCHS can be determined as 24.3 wt% and 32.6 wt% by subtracting the weight loss of silica templates at 900 C ( Fig. S5b †), indicating that the intermediate DCSCHS contain more carbon than the CSCHS.…”
