Lithium-ion batteries are promising energy storage devices used in several sectors, such as transportation, electronic devices, energy, and industry. The anode is one of the main components of a lithium-ion battery that plays a vital role in the cycle and electrochemical performance of a lithium-ion battery, depending on the active material. Recently, SiO 2 has garnered attention for use as an anode in lithium-ion batteries. SiO 2 has a high specific capacity, good cycle stability, abundance, and low-cost processing. However, the high expansion and shrinkage of the SiO 2 volume during lithiation/delithiation, low conductivity, and solid electrolyte interphase formation resulted in damage to the electrode structure and caused a decrease in SiO 2 performance as an anode for a lithium-ion battery. The modified properties of SiO 2 and the use of carbon materials as composites of SiO 2 are effective strategies to overcome these problems. This review focuses on analyzing the role of various carbon materials in composite SiO 2 /C to enhance the performance of SiO 2 materials.

As a clean and renewable energy source, solar energy is a competitive alternative to replace conventional fossil fuels. Nevertheless, its serious fluctuating nature usually leads to a poor alignment with the actual energy demand. To solve this problem, the direct solar-to-electrochemical energy conversion and storage have been regarded as a feasible strategy. In this context, the development of high-performance integrated devices based on solar energy conversion parts (i.e., solar cells or photoelectrodes) and electrochemical energy storage units (i.e., rechargeable batteries or supercapacitors [SCs]) has become increasingly necessary and urgent, in which carbon and carbon-based functional materials play a fundamental role in determining their energy conversion/storage performances. Herein, we summarize the latest progress on these integrated devices for solar electricity energy conversion and storage, with special emphasis on the critical role of carbon-based functional materials. First, principles of integrated devices are introduced, especially roles of carbon-based materials in these hybrid energy devices. Then, two major types of important integrated devices, including photovoltaic and photoelectrochemicalrechargeable batteries or SCs, are discussed in detail. Finally, key challenges and opportunities in the future development are also discussed. By this review, we hope to pave an avenue toward the development of stable and efficient devices for solar energy conversion and storage.

Flexible carbon films are considered the priority choice for flexible sensor electrodes or battery current collectors because of their high electrical conductivity and excellent mechanical flexibility. [9][10][11][12] Among different nanoscopic forms of carbon, 1D CNFs have aroused great interest since it is easy to be processed into flexible films. In particular, when the fiber size is reduced from the traditional micron to nanoscale, the ultrahigh specific surface area and rich defect structure brought by diameter refinement can greatly improve the physicochemical properties of CNF films. [13][14][15] Therefore, CNFs have become a research hotspot in both academia and industry. [16,17] The commonly used strategies to prepare CNFs include the template method, [18][19][20] arc approach, [21,22] chemical vapor deposition (CVD), [23][24][25][26] blend spinning, and electrospinning. [27][28][29][30] For template and arc techniques, the production efficiency of them is very low and it is difficult for them to yield continuous 1D CNFs. For CVD, the expensive equipment limits its large-scale manufacturing of CNFs. Although blend spinning can scalably produce CNFs at high speed in a cost-effective manner, the diameter of the CNFs is generally uneven and large than 500 nm, causing difficulty in controlling the fiber structure. In contrast, electrospinning, as a new fiber forming technology to realize polymer fluid stretching and refinement through a high electrostatic voltage, exhibits many advantages for preparing CNFs. For example, the size effect and surface effect of CNFs prepared by electrospinning are prominent, such as high specific surface areas, surface energy, and surface porosity. Moreover, the structure and surface of CNF can be easily controlled and functionalized, respectively, which endow the electrospun CNFs with a broad application prospect.Despite all these benefits, the mechanical brittleness of electrospun CNFs is still an obstacle that remains to be tackled. [31][32][33] From a microscopic point of view, the mechanical brittleness of CNFs is caused by stress concentration at the defects in CNFs during bending. The main strategy to fabricate flexible CNFs is to ex situ or in situ construct heterogeneous phases into carbon matrix by using surface decoration or doping metal oxide nanoparticles (Nps), [34,35] non-metallic oxide Nps, [36][37][38] and carbide NPs. [39][40][41] The common point of these methods is to establish heterogeneous interfaces between NPs and carbon components Carbon nanofibers (CNFs) fabricated through traditional methods are generally composed of amorphous carbon and graphite sheets, which usually endow CNFs with high modulus and brittleness. Here, a strategy of controlling graphite sheet structures in CNFs for the scalable fabrication of silk-like flexible CNF films that can be arbitrarily folded in any shape and can undergo thousands of dynamic bending deformation cycles is reported. In detail, the carbon precursor of polyacrylonitrile (PAN) is first electrospun into NFs and the...
