lead to problems such as electrode pulverization, current collector detachment, and unstable SEI, which severely limit its commercialization process.<\/p><p><strong>Silicon suboxide<\/strong> (SiOx) is a derivative material of Si, because the inert matrix such as Li2O and Li2SiO4 produced during the first lithium intercalation process reduces the expansion rate, it has obvious advantages in ensuring high energy density and simultaneous cycle performance, making it considered to have better industrial application prospects.<\/p><h2 id=\"Structure-of-silicon-suboxide\">Structure of silicon suboxide<\/h2><p>Silicon suboxide is not a single phase, A. Hohl et al. based on random bonding (RB) and random mixing (RM) model high-resolution transmission electron microscopy (HR-TEM), X-ray photoelectron spectroscopy (XPS) and other test results, a structural model of silicon suboxide material &#8211; interfacial cluster mixing (ICM) model is proposed.<\/p><p>In the ICM model, silicon suboxide is described as composed of many uniformly distributed nano-scale Si clusters, SiO2 clusters and sub-oxidized interface regions between them. On this basis, Schulmeister et al. observed through experiments that there is a silicon suboxide interface boundary layer between the amorphous Si and SiO2 phases, the number of atoms in the interface layer accounts for about 20%\u201325% of the total number of atoms in SiO, and the ratio of Si and O is close to 1:1.<\/p><p>In 2016, Chen et al. reported for the first time the relevant experimental evidence of the atomic scale imbalance of amorphous SiO. Using Angstrom beam electron diffraction (ABED), the coordinates corresponding to the silicon suboxide tetrahedron were detected at the Si\/SiO2 interface layer; Based on the results of ABED and synchrotron radiation X-ray scattering, combined with computer simulations, the team proposed a structural model of disproportionated SiO.<\/p><p style=\"text-align: center\"><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter size-full wp-image-62212\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Structure-model-of-disproportionated-SiO.jpg\" alt=\"Structure model of disproportionated SiO\" width=\"1000\" height=\"560\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Structure-model-of-disproportionated-SiO.jpg 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Structure-model-of-disproportionated-SiO-300x168.jpg 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Structure-model-of-disproportionated-SiO-768x430.jpg 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Structure-model-of-disproportionated-SiO-600x336.jpg 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><span style=\"color: #999999\">Structure model of disproportionated SiO<\/span><\/p><p>(a) In situ structures and atomic structure models of amorphous Si, silicon suboxide, and SiO2;<br \/>(b) Structural model of amorphous SiO;<br \/>(c) The proportions of the five components present in amorphous SiO<\/p><p>By increasing the x value in the silicon suboxide, the irreversible Li2O phase can be generated during charging and discharging, and the kinetics can be accelerated, and the stress generated by the volume expansion can be effectively released, thereby achieving smaller volume expansion.<\/p><p>Therefore, by increasing the oxygen content in the silicon-oxygen anode material, the problem caused by the high expansion rate of the silicon-based battery can be alleviated, and the cycle stability can be greatly improved.<\/p><p>However, as the oxygen content in silicon-oxygen anode materials increases, the electrochemically active lithium storage phase (\u03b1-Si) decreases, resulting in the increase of irreversible phases Li2O and Li4SiO4, so the specific capacity decreases and the first coulombic efficiency (ICE) decreases.<\/p><h2 id=\"Silicon-suboxide-lithium-storage-mechanism\">Silicon suboxide lithium storage mechanism<\/h2><p>Compared with the lithium intercalation mechanism of simple silicon, the presence of oxygen makes the reaction mechanism between silicon suboxide and Li more complicated. At present, people&#8217;s general understanding of the lithium intercalation mechanism of silicon suboxide is:<\/p><p>Silicon suboxide reacts with lithium first to form elemental silicon, Li2O and lithium silicates (Li4SiO4, Li2SiO3, and Li2SiO5, etc.), and elemental silicon further reacts with Li to form LixSi alloy, resulting in reversible capacity. The generated Li2O and lithium silicate no longer participate in the reaction during the subsequent electrochemical cycle, resulting in a low ICE of the material, but it can buffer the volume expansion and protect the active material.<\/p><p>In addition, in the irreversible matrix, the proportion of lithium silicate is significantly higher than that of Li2O, despite the small proportion of Li2O in the lithiated component, the diffusion rate of Li+ in Li2O is at least two orders of magnitude higher than that in lithium silicate. Therefore, it can serve as a Li+ transport channel, thereby improving the capacity and rate performance of the silicon suboxide anode.<\/p><p><img decoding=\"async\" class=\"aligncenter size-full wp-image-62207\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Schematic-diagram-of-SiO-anode-lithiation-and-delithiation-process.jpg\" alt=\"Schematic diagram of SiO anode lithiation and delithiation process\" width=\"1000\" height=\"320\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Schematic-diagram-of-SiO-anode-lithiation-and-delithiation-process.jpg 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Schematic-diagram-of-SiO-anode-lithiation-and-delithiation-process-300x96.jpg 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Schematic-diagram-of-SiO-anode-lithiation-and-delithiation-process-768x246.jpg 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Schematic-diagram-of-SiO-anode-lithiation-and-delithiation-process-600x192.jpg 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><p style=\"text-align: center\"><span style=\"color: #999999\">(a)Schematic diagram of SiO anode lithiation and delithiation process; (b) Li+ diffusivity coefficient and capacity relationship diagram of different components produced during SiO anode lithiation process<\/span><\/p><h2 id=\"Defects-and-optimization-measures-of-silicon-suboxide\">Defects and optimization measures of silicon suboxide<\/h2><p>At present, silicon suboxide anode materials mainly have the following problems:<\/p><p>\u25cf The volume expansion is still large (~200%);<br \/>\u25cf The first coulombic efficiency and specific capacity are low;<br \/>\u25cf Low conductivity.

Silica material has a smaller volume effect and more stable cycle performance, and is more widely used. It can be used in various batteries such as steel shells, pouch batteries, and prismatic aluminum shells.<\/p><p>At present, through structural optimization and interface modification of silicon suboxide anodes, the volume effect of electrode materials has been suppressed to a certain extent, and its long-term cycle stability has been significantly improved. However, the problem of low Coulombic efficiency for the first time in the silicon suboxide anode battery is still a key bottleneck that plagues its industrial application.<\/p><p>Therefore, silicon suboxide anode materials still need further efforts and exploration. It is believed that in the near future, silicon suboxide anode materials will surely make a breakthrough, and will occupy an important position in the anode material market for next-generation high-energy-density lithium-ion batteries.<\/p><p>If you are interested in battery anode material industry information, you can refer to top 10 <a
