The upstream and downstream of the industrial chain continue to benefit, driving the development of the silicon-oxygen anode material industry to accelerate

Silicon-based anode materials can usually be divided into two types: silicon-oxygen anode materials and silicon-carbon anode materials. Silicon-oxygen anode material refers to a porous three-dimensional structural material formed by silicon oxide particles (SiOx). It has the advantages of high conductivity, high specific capacity, good stability, green environmental protection, and low production cost. It is widely used in power batteries and new energy storage. It is widely used in systems and other fields.

The upstream of the silicon-oxygen anode material industry chain supplies raw materials, including nano-silica powder and silicon dioxide. Silica, commonly known as quartz, has the advantages of low expansion rate, high hardness, good chemical stability, corrosion resistance, and strong adsorption. It can be used to prepare silicon monoxide, the precursor of silicon-oxygen negative electrode material. The main preparation methods of silica include dissociation method, gas phase method and precipitation method. After years of development, the maturity of my country’s silicon dioxide technology has continued to improve, and it has become one of the world’s major producing countries. This has laid a good foundation for the development of the silicon-oxygen anode material industry.

According to the “2023-2028 China Silicon Oxygen Anode Material Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , The downstream of the silicon-oxygen anode material industry chain is application fields, including power batteries, new energy storage systems, etc. Silicon-oxygen anode materials are the mainstream product of silicon-based anode materials. They have the advantages of low production cost and high technological maturity. They can be used to manufacture oxide solid-state batteries, lithium-ion batteries and other products. In recent years, as the prosperity of my country’s new energy automobile industry has increased, the market demand for lithium-ion batteries as power batteries has become increasingly strong. Against this background, the development speed of my country’s silicon-oxygen anode material industry will further accelerate.

my country’s silicon-oxygen anode material manufacturers include Beterui, Xiangfenghua, Tianmu Leading, Huineng Technology, etc. Betri is the largest silicon-based anode material manufacturer in my country, with large-scale production capabilities of silicon-oxygen anode materials and silicon-carbon anode materials. Silicon-oxygen anode DXA8-LA and silicon-oxygen anode DXA5-LA are its representative products of silicon-carbon anode materials. In 2022, Beterui’s silicon-oxygen anode material production capacity will reach 2,500 tons, accounting for nearly 50% of its total silicon-based anode material production capacity.

Globally, with the improvement of industry prosperity, global enthusiasm for the research and development of silicon-oxygen anode materials continues to rise, and many new developments have been made. In July 2023, a scientific research team from Dalhousie University in Canada successfully produced silicon monoxide powder with controllable oxygen content using ball milling technology. This product can improve the cycle life and specific capacity of silicon-oxygen anode materials and will be used in the future. during commercial battery production.

Industry analysts said that silicon-oxygen anode materials are cost-effective and have broad application prospects in the field of battery manufacturing. In recent years, with the continued efforts of local companies, my country’s silicon-oxygen anode material production capacity has continued to expand. It is expected that in the future, with in-depth research and technological progress, the silicon-oxygen anode material industry will gradually develop towards high quality and high performance.
