“…The four samples exhibit an embedded lithium/de-lithium plateau similar to that of Si, with a plateau around 0 V corresponding to embedded lithium and around 0.4 V corresponding to the de-lithiumization process, which suggests that in the composite structure, Si is still the main storage capacity host for Li-storage. 4 The specific charge/discharge capacities of the SC-T samples labeled in Fig. 4a show a gradual decreasing capacity with increasing Ti source content, which is attributed to a relative decrease in the amount of high-capacity Si.…”

“…[1][2][3] Currently, silicon (Si) is considered to be one of the most promising commercial anode materials with its superior theoretical specific capacity (∼4200 mA h g −1 , graphite (G) 372 mA h g −1 ) lower deintercalation lithium potential (∼0.5 V) and extremely high reserves, the second highest in the earth's crust, as compared with the traditional carbon-based material commercial G anode. [4][5][6] However, alloy-type anode materials form a series of Li-Si alloy phases during the lithiation process, leading to a volume expansion more than three times larger than that of pure Si. This huge volume change occurring during charge and discharge, often results in electrode cracking and degradation, thereby impacting battery lifespan; [7][8][9] additionally, pure Si has poor electron conductivity as compared to G and thus affects its rate performance, which is one challenge we have faced toward the industrial application of Si-based anode materials.…”

“…In addition, the introduction of heteroatoms such as N, S, P into the carbon coating layer also have been widely explored to tune the electronic and textural properties for preparing high-performance Si@C T h i s c o n t e n t i s composites in LIBs. 14 For instance, Zeng et al 15 designed Ndoped porous Si@C composite materials, which provided a high final reversible specific capacity of 538.6 mAh/g at 0.5 A/ g over 500 cycles in LIBs.

Nano-silicon (Si) integrating carbonous material has been recognized as a viable approach for restraining the intrinsic serious volume change and enhancing poor conductivity, finally resulting in improved electrochemical properties, including capacity, rate performance, and cycling life-span. Nevertheless, it remains a huge challenge via a straightforward strategy to obtain the homogeneous Si@C composite with an exceptional Li + storage performance. Herein, novel Si integrating a S, N co-doped carbon shell and a graphite composite material (Si@C/SN@Graphite) have been prepared through combining in situ carbon coating with a liquid-phase ball milling method, in which thiourea was used as dopant, poly(ethylene glycols) were used as carbon coating precursor, and graphite was utilized as carbon matrix. The combined effect of the S and N co-doping carbon coating layer and graphite sheet is sufficient to efficiently restrain the serious volume expansion, enhance electronic conductivity, and provide numerous Li + storage rooms for Si anode. Furthermore, the theoretical simulation and electrochemical testing have been carried out to further demonstrate the superiority of the S, N co-doped carbon coating layer. As a result, the as-prepared Si@C/SN anode delivers a notable initial Coulombic efficiency (ICE) of 91%, high reversible capacity of 1213 mAh/g at 2 A/g within 0−1.0 V coupled with 92.8% capacity retention rate for 400 cycles. Moreover, the Si@C/SN@Graphite anode exhibits outstanding reversible capacities of 690 and 379 mAh/g at 0.05 and 1 A/g within 0−2 V along with a 90% capacity retention rate for 500 cycles. Additionally, the full cell assembled by using Si@C/SN@Graphite as anode and LiFePO 4 as cathode presents reversible capacities of 176.5 and 137.9 mAh/g at 0.2 and 3 C, respectively, and considerable ICE of 92% as well as 90% capacity retention for 200 cycles. This work provides a facile and cost-effective strategy for obtaining Si@C composites with exceptional Li-ion storage capabilities in LIBs.

Silicon (Si) is considered to be the promising candidate anode for the next generation of high‐energy‐density batteries. However, the poor initial coulombic efficiency (ICE) and rate performance severely hinder its commercial development. Here, fully exploits the 2D structure of photovoltaic silicon waste (PV‐WSi), combining with the advantage of controllable depositing layers offered by fluidized bed atomic layer deposition (FBALD), to simultaneously achieve high ICE and highrate performance of Si‐based anodes. The characteristic of Li+ embedding vertically into the plane direction of the 2D sheet‐like structure of PV‐WSi helps shorten the diffusion distance, alleviating the pulverization problem caused by volume expansion. FBALD is utilized to controllably deposit Li2O (≈1 nm) and TiO2 (≈4 nm) layers to compensate for the loss of Li sources, further suppressing the volume expansion of Si and isolating the side reactions between Si and electrolyte. The prepared Si@Li2O@TiO2 demonstrates ultrahigh ICE (90.9%) and outstanding rate performance (>900 mAh g−1 at a rate of 20 A g−1). Full cells with the Si@Li2O@TiO2 anode and LiFePO4 cathode deliver a stable capacity of 100 mAh g−1 after 300 cycles at 0.5 C. This work provides new ideas for the development of high ICE, high‐rate Si‐based anodes based on low‐cost photovoltaic waste.
