“…However, the carbon material suffers from poor rate capability and safety originating from the formation of lithium dendrites owing to its low Li-intercalation potential close to 0 V (vs. Li/Li + ). 3 To solve these problems, the spinel Li 4 Ti 5 O 12 (LTO) with good rate capability and safety, has been developed as a new commercial candidate. 4 Nevertheless, its small theoretical specic capacity (175 mA h g À1 ) restricts it from being widely used in LIBs with high energy density.…”

“…In summary, various characterization studies have been conducted to find Si‐based electrodes (e.g., pure Si, Si oxides, and Si composites) with favorable compositions and structures and to clarify the different interactions among the electrode, electrolyte and other components; these studies demonstrated modification strategies of anode materials, electrolytes, or others (binders, conductive carbon, and so on) that satisfy the comprehensive requirements of practical LIBs . The following sections will describe recent advances in characterization methods concerning compositions, morphologies and crystal structures, revealing the key for improving the battery performance.…”

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.

“…Nanostructure design is an effective way to improve battery cycling because nanostructures provide short diffusion length for Li + ions and electrons with better resistance to fracture. Si (4200 mAh/g)-, Sn (992 mAh/g)-, and SnO2 (782 mAh/g)-based anodes have high gravimetric and volumetric capacities, so they are the most attractive and widely investigated candidate materials among the different alloys [16][17][18]. The most widely used anode is graphite, whose lithiated compounds have stable phases up to the LiC 6 stoichiometry, corresponding to a theoretical specific capacity of 372 mAh/g [19].…”

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.
