Since 2011, GCL has independently developed FBR granular silicon technology, successfully creating an innovative product with independent intellectual property rights—FBR granular silicon—and entering the replicable production era characterized by "systematization, standardization, digitization, integration, intelligence, and modularization." Currently, GCL has established granular silicon production bases in Jiangsu, Sichuan, Inner Mongolia, and other locations, achieving an annual production capacity of 480,000 tons of FBR granular silicon. Compared to traditional rod silicon, granular silicon demonstrates significant energy consumption advantages, with substantial reductions in comprehensive power consumption, labor costs, water consumption, and hydrogen consumption. Simultaneously, granular silicon has gained high recognition in the industry for its superior fluidity, lower costs, more stable quality, and superior carbon footprint. It has received dual carbon footprint certification in the photovoltaic raw material sector in both China and France, initiating a new era of photovoltaic material revolution and low-carbon applications with the lowest carbon footprint in the global industry.

As the global leader in granular silicon production capacity, GCL's production bases possess an annual silane gas production capacity exceeding 600,000 tons to support FBR granular silicon production. This includes over 150,000 tons in Xuzhou, Jiangsu; over 150,000 tons in Leshan, Sichuan; over 150,000 tons in Baotou, Inner Mongolia; and over 150,000 tons in Hohhot, Inner Mongolia. To ensure granular silicon production, most of the silane gas capacity is currently used in-house, with filling capacity exceeding 10,000 tons within the year, and it has the ability to adjust and expand.
Currently, the company's silane gas quality reaches electronic grade, with significant advantages in large output, high purity, and stable supply. The portion sold externally accounts for approximately 25% of the domestic market share. Due to its unique advantage of adjustable and expandable capacity, the company will flexibly adjust the proportion of silane gas for internal use and external sales based on market conditions in the future, becoming a crucial growth driver for the company's development.

GCL's silicon-carbon anode materials can replace graphite, featuring high energy density and significantly improving the capacity and electrochemical performance of battery anode materials. As an extension project of GCL's silicon industry chain, the raw materials for silicon-carbon anodes (silicon powder, silane) are sourced from FBR granular silicon equipment. The silicon-carbon anode materials produced by GCL's nanoscale silicon material technology have a single product specific capacity greater than 1500 and an initial charge/discharge efficiency reaching 91%.
