“…In the case of a Si‐based system, the cyclic stability also strongly depends on the binders, since an effective binder can prevent the Si particles from pulverization and subsequently electrical isolation . If this isolation occurs, the peak width and position in the HAXPES Si 1s spectra is affected by the charge‐up effect arising from the continuous photoelectron emission under high electron‐beam density .…”

With the remarkably large theoretical specific capacity of silicon (Si), Si‐based rechargeable lithium‐ion batteries (LIBs) have attracted great interest, as they are expected to meet the growing demand for large‐scale energy storage devices, electric vehicles, and portable electronic devices with high energy density. However, the Si‐based LIB faces great challenges due to the cyclic volume changes induced by Si, which lead to considerable capacity fading. To facilitate the use of high‐performance LIBs enabled by Si‐based anodes, understanding the fading mechanism is necessary. In this regard, various advanced characterization methods have been developed to reveal the fading mechanism and to develop a modification strategy associated with compositional and structural evolution. In this review, the general understanding of the fading mechanism and the technical specifications of Si‐based LIBs are discussed. The recent progress in advanced characterization methods for Si‐based LIBs is summarized with respect to the achievements in compositional and structural interpretation. Several possible future research directions for Si‐based LIBs and the expected development trends in relevant characterization methods are also discussed.

“…The self‐healing property arising from hydrogen bonds between the oxygen‐rich SRD and the hydroxyl‐rich SA can effectively mitigate the pulverization‐induced capacity decay and improve the cycling performance of SRD. Zhang and co‐workers [ 135 ] reported the self‐healing silicon‐sodium alginate‐polyaniline (Si‐SA‐PANI) composites anode for LIBs (Figure 16b). By the density functional theory (DFT) calculations, the synergy effect of SA and PANI was found to enhance the hydrogen bonding between the Si and polymers, and increase the electron transport capability, resulting in excellent electrochemical performances.…”

The booming development of electronics, electric vehicles, and grid storage stations has led to a high demand for advanced energy‐storage devices (ESDs) and accompanied attention to their reliability under various circumstances. Self‐healing is the ability of an organism to repair damage and restore function through its own internal vitality. Inspired by this, brilliant designs have emerged in recent years using self‐healing materials to significantly improve the lifespan, durability, and safety of ESDs. Extrinsic and intrinsic self‐healing materials and their working principles are first introduced. Then, the application of self‐healing materials in ESDs according to their self‐healing chemistry, including hydrogen bonds, electrostatic interactions, and borate ester bonds, are described in detail. Based on these, critical challenges and important future directions of self‐healing ESDs are discussed.

“…Electrochemical There are two strategies to avoid this problem. The first is combining Si with different kinds of carbon materials such as amorphous carbon [25][26][27], conductive carbon black [28], carbon nanotubes [29,30], and graphene [31][32][33], and the second is by designing nanoscale silicon with different structures. Currently, extensive research has been carried out to develop nanostructures of silicon i.e., silicon nanoparticles [27,34,35], silicon nanowires/nanotubes [36][37][38], nanosheets [38,39], and 3D porous structures [40,41].…”

Nanostructured Silicon as Potential Anode Material for Li-Ion Batteries

Commercial micrometer silicon (Si) powder was investigated as a potential anode material for lithium ion (Li-ion) batteries. The characterization of this powder showed the mean particle size of approx.75.2 nm, BET surface area of 10.6 m2/g and average pore size of 0.56 nm. Its band gap was estimated to 1.35 eV as determined using UV-Vis diffuse reflectance spectra. In order to increase the surface area and porosity which is important for Li-ion batteries, the starting Si powder was ball-milled and threatened by metal-assisted chemical etching. The mechanochemical treatment resulted in decrease of the particle size from 75 nm to 29 nm, an increase of the BET surface area and average pore size to 16.7 m2/g and 1.26 nm, respectively, and broadening of the X-ray powder diffraction (XRD) lines. The XRD patterns of silver metal-assisted chemical etching (MACE) sample showed strong and narrow diffraction lines typical for powder silicon and low-intensity diffraction lines typical for silver. The metal-assisted chemical etching of starting Si material resulted in a decrease of surface area to 7.3 m2/g and an increase of the average pore size to 3.44 nm. These three materials were used as the anode material in lithium-ion cells, and their electrochemical properties were investigated by cyclic voltammetry and galvanostatic charge-discharge cycles. The enhanced electrochemical performance of the sample prepared by MACE is attributed to increase in pore size, which are large enough for easy lithiation. These are the positive aspects of the application of MACE in the development of an anode material for Li-ion batteries.
