Low‐cost and scalable processes to fabricate Si‐based anodes with high areal capacity and excellent cycling performance remain a challenge, thereby limiting their widespread application. Herein, we report Si nanoparticles@conductive carbon framework@polymer (Si@C@P) composite electrodes, in which Si nanoparticles are homogeneously immobilized within a three‐dimensional network of conductive carbon nanofibers bound by a high‐viscosity polymer. When used as anodes for lithium‐ion batteries, the obtained Si@C@P composite electrodes deliver an initial coulombic efficiency of 83.5 % and an areal capacity of 2.0 mAh cm−2 (1152 mAh gnormalenormallnormalenormalcnormaltnormalrnormalonormaldnormale-1 ), with a capacity retention about 0.8 mAh cm−2 (466 mAh gnormalenormallnormalenormalcnormaltnormalrnormalonormaldnormale-1 ) after 150 discharge–charge cycles at 0.1 C. This work provides a low‐cost route for the large‐scale manufacture of Si‐based anodes with high areal capacity, which may be very significant for the development of lithium‐ion batteries with high energy density.

“…Thus, inexpensive and industrial acceptable nanostructure preparation methods needs to be developed. [114,115] For example physical methods (such as chemical vapor deposition) provide better control over structure and morphology of nanostructures but at very high cost that limits their extension to EVs. [116,117] In contrast to this, wet chemistry provides low cost synthesis that can be afforded by the road market but results poor control over the structure and composition of nanostructured anode materials.…”

Lithium ion batteries (LIBs) possess energy densities higher than those of the conventional batteries, but their lower power densities and poor cycling lives are critical challenges for their applications to electric vehicles (EVs) or grid stations. The energy and power densities, as well as the life of LIBs are dependent on electrodes where sluggish diffusion control process and structural stability are the main concerns. Here, the lithium storage mechanism of anode materials and the Goodenough diagram to explain the potential of cell and key parameters to determine the performance of an anode are highlighted. The cost reduction parameters and the availability of anode materials for future batteries on the basis of their resources and performances will be discussed. Further, the recent progress on anode nanostructures and solutions to the associated challenges will be outlined. The use of several techniques to determine the dynamic variations in nanostructures including both structural and chemical changes of electrode nanostructures during cycling as well as the limitations for high load applications will be explained. Finally, the concluding remarks will highlight the characteristics for both anode and cathode for better choice of electrode combinations in the full batteries.

“…To further improve the silicon mass loading, Leveau et al reported a novel silicon nano-tree structural anode using a two-step CVD process, as shown in Figure 7a. [100] After the first traditional deposition process (Figure 7b), another catalyst layer was evaporated on the as-prepared Si NWs electrode and followed by a second CVD process (Figure 7c). It is worth mentioning that the silicon content of the ultimate electrode is strongly impacted by the thickness of catalyst layer and the growth time of each step.…”

Silicon (Si) is promising for high capacity anodes in lithium-ion batteries due to its high theoretical capacity, low working potential, and natural abundance. However, there are two main drawbacks that impede its further practical applications. One is the huge volume expansion generating during lithiation and delithiation progresses, which leads to severe structural pulverization and subsequently rapid capacity fading of the electrode. The other is the relatively low intrinsic electronic conductivity, therefore, seriously impacting the rate performance. In the past decades, numerous efforts have been devoted for improving the cycling stability and rate capability by rational designs of different nanostructures of Si materials and incorporations with some conductive agents. In this review, the authors summarize the exciting recent research works and focus on not only the synthesis techniques, but also the composition strategies of silicon nanostructures. The advantages and disadvantages of the nanostructures as well as the perspective of this research field are also discussed. We aim to give some reference for engineering application on Si anodes in lithium ion batteries.
