Life expectancy will be greatly reduced.<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">Due to the huge volume change during lithium deintercalation, the expansion of silicon\u00a0negative electrode materials will cause a series of problems, including:<\/span><\/p>\n<ol>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">The volume expansion effect will generate a large amount of shear stress and compressive stress, which will break the silicon particles, increase the internal resistance, affect the direct transmission of electrons on the electrode, and seriously cause some active materials to completely lose their electrochemical activity;<\/span><\/li>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">For the entire electrode, the volume change leads to structural collapse and electrode peeling, resulting in the interruption of the electrical contact between the electrode material and the current collector, and the loss of contact between the active material and the conductive agent and binder, resulting in capacity fading.<\/span><\/li>\n<\/ol>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">(2)\u00a0The first Coulombic efficiency is low<\/span><\/h3>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">The first Coulombic efficiency (referred to as the first effect) is an indicator to measure the charge and discharge capacity of lithium-ion batteries.

The volume change makes it impossible to form a stable SEI layer on the surface of the Si electrode, and the SEI layer is repeatedly broken and formed, consuming a large amount of Li+ ions; at the same time, the thickness of the SEI increases with the electrochemical cycle, and an excessively thick SEI layer hinders electron transfer and Li+ ion diffusion. increases, the polarization increases.<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\"><em><i>Based on the current situation, it is believed that silicon is a strong contender for the next-generation anode material of <a href=\"https:\/\/harveypoweress.com\/nl\/lithium-batteries-for-inverter-systems\/\" target=\"_blank\" rel=\"noopener\">lithium batteries<\/a>.

If a large amount of graphene is added, the proportion of silicon in the battery will be reduced, and the overall capacity of the battery will be reduced. Silicon adds energy that can be stored in the battery. Due to the addition of a small amount of graphene, it is possible to prevent the failure of the battery structure while maintaining the battery capacity.<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">The EU-funded Graphene Flagship has helped advance this research in several ways. In the first phase of the project, not only was the initial idea of developing graphene-added batteries decided, but the company BeDimensional was established specifically to supply graphene materials and to develop many graphene-based batteries using a patented graphene production method. new technology.<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">The Synergistic Uses of the Graphene Flagship brings together cutting-edge research efforts from IIT companies, newly spin-off BeDimensional companies, and established industrial manufacturers like VARTA for integrated innovation.

Among them, recombination, silicon oxidation, nanotechnology, and pre-lithiation technology are relatively mature and have begun to be applied in industrialization.<\/span><\/p>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">(1)\u00a0Silicon oxide technology<\/span><\/h3>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">The silicon oxide technology route mostly uses silicon oxide. Compared with elemental silicon particles, silicon oxide (SiOx) has a smaller volume expansion during the lithium intercalation process, so its cycle stability is significantly improved compared with pure silicon negative electrodes, but The silicon oxide negative electrode will produce inactive substances such as Li2O during the charge and discharge process, resulting in low initial efficiency of the SiOx material (about 70%).<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">Generally, silicon oxide is doped with a doping content of about 5%. The theoretical specific capacity of the silicon oxide negative electrode is 2600mAh\/g and the cycle stability is good. Major negative electrode material manufacturers have plans for the silicon oxide negative electrode. Japan's Shin-Etsu Chemical, South Korea's Dazhou, China's Shanshan Co., Ltd., and Betray are all able to mass-produce silicon-oxygen anodes. Silicon oxide negative electrodes have been partially applied in fields such as power tools and high-end digital.<\/span><\/p>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">(2) Nanoization<\/span><\/h3>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">By reducing the particle size of the silicon\u00a0material to the nanometer level, the volume change of the silicon\u00a0material during charging and discharging can also be improved. Nano-scale silicon materials have smaller particle sizes and more voids, which are easier to buffer the stress and deformation of silicon during the process of lithium ion extraction and extraction.<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">In addition, nanoparticles can shorten the diffusion distance of lithium ions and increase the lithium storage capacity of silicon materials. Although silicon nanowire anode has many advantages, its high production cost and poor material uniformity limit its large-scale application to a certain extent.<\/span><\/p>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">(3) Composite<\/span><\/h3>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">The preparation of silicon\u00a0composite materials by compounding other materials can not only improve the conductivity of silicon\u00a0materials, but also serve as a buffer layer to withstand the volume effect of silicon during charging and discharging.<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">Silicon-carbon composite material (silicon-carbon anode) is the most rapidly industrialized preparation method due to its advantages of good stability, small volume change and excellent electrical conductivity. The sponge silicon anode released by GAC Group and the silicon anode patent held by SiILion, which Tesla acquired in 2021, are essentially composite structures formed by combining silicon and carbon materials.<\/span><\/p>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">(4) Porosity<\/span><\/h3>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">In addition to reducing the size of silicon particles, designing porous silicon with void spaces is also an effective way to slow down the volume expansion. The void space in porous silicon can effectively reduce the volume effect caused by the intercalation and extraction of lithium in silicon particles. In addition, the void can also accelerate the wettability of the electrolyte, improve the transmission and diffusion efficiency of lithium ions in the active material, and improve the efficiency of the material. electrical conductivity.<\/span><\/p>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">(5) Pre-lithiation<\/span><\/h3>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">Pre-lithiation technology is an important way to improve the initial low efficiency of silicon anodes. In order to ensure the performance of silicon\u00a0anodes, it is necessary to replenish the lithium ions lost in the first cycle. Pre-lithiation technology mainly includes electrochemical pre-lithiation and adding pre-lithiation additives (lithium supplementation agents) to positive and negative electrode materials. Among them, the method of adding lithium supplementation agents is relatively mature.<\/span><\/p>\n<p>\u00a0<\/p>\n<h2><span style=\"font-family: helvetica, arial, sans-serif;\">Silicon Lithium Battery Market<\/span><\/h2>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">(1) Market demand<\/span><\/h3>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">At present, my country's silicon materials are mainly used in the consumer field (electric tools, high-end digital, etc.), and the <a href=\"https:\/\/harveypoweress.com\/nl\/product\/12v-battery\/12v-rv-battery\/\" target=\"_blank\" rel=\"noopener\">power battery<\/a> field is expected to bring exponential growth.<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">Since 2021, benefiting from strong demand in the consumer sector and rising demand in the international market, my country's demand for composite silicon shipments has increased from 0.6 in 2020 to 11,000 tons in 2021.
