“…CNFs can be used alone, without Cu or Al foils and binder materials [92,96,165,166,255]. The current collector (Al or Cu metal foil) occupies a significant volume (10e12%) in the LIB cell; the elimination of the collector, binder, and associated organic binder solvents such as toxic NMP, could provide positive environmental impacts and cost reduction [148,246e249,256].…”

“…Liu et al reported Ti‐doped SnO x nanoparticles with varied molar ratios of Ti/Sn (0.05, 0.1, and 0.2), which were embedded in the carbon nanofibers through electrospinning technique and the subsequent thermal treatments . The precursor solution for the electrospinning was prepared by mixing polyacrylonitrile dissolved in N , N ‐dimethylformamide with another solution containing anhydrous TiCl 4 and SnCl 4 in ethylene glycol, where Ti/Sn ratio could readily be adjusted.…”

SnO(x) (x = 0, 1, 2) and TiO(2) are widely considered to be potential anode candidates for next generation lithium ion batteries. In terms of the lithium storage mechanisms, TiO(2) anodes operate on the base of the Li ion intercalation-deintercalation, and they typically display long cycling life and high rate capability, arising from the negligible cell volume change during the discharge-charge process, while their performance is limited by low specific capacity and low electronic conductivity. SnO(x) anodes rely on the alloying-dealloying reaction with Li ions, and typically exhibit large specific capacity but poor cycling performance, originating from the extremely large volume change and thus the resultant pulverization problems. Making use of their advantages and minimizing the disadvantages, numerous strategies have been developed in the recent years to design composite nanostructured Sn-Ti-O ternary systems. This Review aims to provide rational understanding on their design and the improvement of electrochemical properties of such systems, including SnO(x) -TiO(2) nanocomposites mixing at nanoscale and nanostructured Sn(x) Ti(1-x) O(2) solid solutions doped at the atomic level, as well as their combinations with carbon-based nanomaterials.

“…In recent literature, Yu et al [83][84][85][86] have achieved the in-site addition of transition metallic (Ti and Cu) and nonmetallic elements (P and B) into SnO x /CNF composites for the enhancement of cycling stability and rate performance via the electrospinning technique and subsequent thermal treatments. It was demonstrated that the doped SnO x nanoparticles were all ultrafine and uniformly dispersed in the conductive CNF matrix, and the doping content should be kept to an optimal value.…”

Considerable efforts have been devoted to the research of high-performance and longlifespan lithium-ion batteries LI"s for their applications in large-scale power units. "s one of the most important components in LI"s, anode plays an important role in determining the overall performance of LI"s. Nowadays, graphite has been the most successfully commercialized anode material. However, its limited theoretical capacity m" h g − and limited power density seems insufficient for the next-generation LI"s. To overcome these problems, new materials with fundamentally higher capacity and higher power density are urgently needed. Recently, there is an ever-increasing interest in developing novel carbonaceous nanomaterials to replace graphite as the anode materials for LI"s. Such materials have included carbon spheres, carbon nanotubes, carbon nanofibers CNFs , porous monoliths, and graphene. "mong these alternative forms of carbon, CNFs and its morphological-controlled derivatives such as porous or hollow CNFs have attracted much attention due to their unique and interesting properties such as one-dimensional D nanostructure, good electronic conductivity, and large surface areas. Moreover, these CNFs can be used to encapsulate various second phases to form some functional composite, meeting further requirements including higher energy density, higher power density or flexible requirements, for the advanced LI" operation.Electrospinning is considered as a simple, versatile, and cost-effective industry-viable technology for preparing various CNFs and their composites in a continuous process, with controllable morphology. Therefore, in this chapter, we have summarized some recent progresses in electrospun nanofibrous carbon-based anode for LI"s, covering the structure evolution from solid CNFs into morphology-designed CNFs, and then their composites with various functional nanoparticles. We anticipate this paper can offer some useful information for some researchers in the area of energy storage and conversion and can inspire them.
