Observation of new materials week: the attention of silicon carbon negative electrode has increased, and the industrialization is expected to accelerate
Lithium ion batteries (LIBS) are widely used in the consumer electronics industry, power energy industry and energy storage equipment industry. They are mainly composed of four key materials: positive electrode, negative electrode, electrolyte and diaphragm. At present, commercial lithium batteries mainly use graphite as negative electrode material, and silicon-based negative electrode materials are environment-friendly and rich in reserves due to high theoretical specific capacity, low lithium removal potential The advantages of low cost have attracted much attention. According to the structure division, silicon-based negative electrode materials are usually divided into three categories: coated, loaded and dispersed. Compared with graphite negative electrode materials, the preparation process of silicon-based negative electrode materials is complex and the technical barriers are high. At present, only a few enterprises in the industry master them, and the products are not standardized, so there are some difficulties in large-scale production. According to GGII data, in 2020, Chinese enterprises shipped 370000 tons of negative electrode materials, with a year-on-year increase of 35%, accounting for nearly 70% of the world. The market growth exceeded expectations, including 6000 tons of silicon-based negative electrode. Since 2021, the pace of development of silicon-based negative electrode technology has accelerated. With the progress of technology R & D and application, GGII expects that the sales of silicon-based negative electrode materials will really start in 2023. By 2025, the global demand for silicon-based negative electrode materials is expected to increase at a compound annual growth rate of 70%. At present, the supply end of silicon-based negative electrode is gradually expanded. In addition to the existing graphite negative electrode enterprises, founding teams of scientific research institutions and battery enterprises, some chemical enterprises or silicon material enterprises have also begun to layout the capacity of silicon-based negative electrode materials. According to the announcement of the company, Zhejiang Xinan Chemical Indusyrial Group Co.Ltd(600596) has completed the construction and operation of the pilot project of silicon-carbon negative electrode materials; Chengdu Guibao Science & Technology Co.Ltd(300019) in 2019, the company built a 50 t / a pilot production line of silicon carbon cathode materials. The products have passed the appraisal, reached the international advanced level, achieved a number of technical achievements, passed the evaluation of several battery manufacturers and achieved small batch supply; In November 2021, it was announced to invest in the new project of 10000 t / a silicon carbon cathode material for lithium battery, 40000 t / a special adhesive production base and lithium battery material R & D center, so as to broaden the company’s new energy business sector.
