(III) Industry development trend

1, Daquan Energy Announcement: From 2022 to 2026, a customer is expected to send a total of Procurement of 30,000 tons of solar-grade polysilicon super clean-free single crystal materials. With the continuous improvement of the concentration of each link in the photovoltaic industry chain, building a reliable supply chain system around "quality, cost, sustainability, and flexibility" has become the focus of sustainable operation of crystalline silicon enterprises.

2. In July 2021, the Silicon Industry Branch of the Nonferrous Metals Association issued the "Industrial Silicon Industry Self-discipline Convention". According to the country's policy requirements for industrial silicon enterprises in terms of business operation, equipment and environmental protection, energy conservation and resource utilization, safety and occupational health, etc., the compliance enterprises are required to declare independently in July every year, and announce it in January of the following year. However, according to the tracking situation this week, no company has taken the initiative to declare. This situation shows in disguise: the overall technical level of the industrial silicon industry (including leading companies) is still far from the national requirements, and the overall level is relatively extensive. Judging from the fact that my country's steel, non-ferrous metals, building materials, photovoltaics and other high-energy-consuming industries have established similar mechanisms, under the background of green and low-carbon development, industrial silicon enterprises will gradually face technological upgrades and refined management. Only by taking the technology-led development path will we be able to seize the medium-to-high-speed development opportunities in this round of the industry.

3 、【Silicon-Based Negative Electrode: New Application of Silicon Materials】High-powered bicycle models have gradually become the trend of the new energy vehicle industry, but the negative electrode As the "short board" problem of improving the energy density of batteries is increasingly prominent. Carbon-based materials are the most widely used anode materials at present, with a theoretical specific capacity of 372mAh/g, while the specific capacity of silicon is as high as 4200mAh/g, which is more than 10 times that of carbon-based materials. It is currently known as the anode material with the highest specific capacity. , the high specific capacity advantage makes silicon-based materials regarded as ideal next-generation anode materials. With the mass production of 4680 large cylindrical batteries and the follow-up of mainstream battery factories, it is expected that silicon-based anodes will show a rapid development trend. However, from a technical point of view, since the volume expansion of silicon materials can reach 120% to 300% during charging and discharging, resulting in the differentiation of silicon particles and the rupture and thickening of the SEI film, the first charging efficiency and life of the battery will be affected. The current solution is that silicon particles provide lithium storage capacity, and carbon materials buffer volume changes, while taking into account high specific capacity and long service life. At present, silicon-carbon composite materials and silicon-oxygen composite materials are the main technical routes of silicon-based anodes. .
