The construction of an electronic grade silane and silicon carbon negative electrode new material project broke ground at Yichang High-Tech Zone on January 10, reflecting the city’s ambition of developing an industry that could potentially generate tens of billion-yuan in revenue each year.
Shaanxi Saineng Ruike Technology Co., Ltd. is investing approximately 5.6 billion yuan (US$764 million) in the project.
The first phase of the project has a designed annual production capacity of 15,000 tons of silane gas. Once completed, it is expected to generate an annual output of approximately 3 billion yuan and tax of approximately 150 million yuan.
Electronic grade silane gas is a key material for semiconductor chips. At present, the domestic annual demand is around 4,500 tons per year, which has long relied on imports.

"We have our own technological advantages and can produce electronic grade silane that meets the needs of the semiconductor industry, substituting imported materials," said Zheng Weiguo, General Manager of Hubei Shenghao New Materials Co., Ltd.
The second phase of the project will further extend the industry chain and use silane to produce silicon-carbon negative electrode and key materials. It has a designed annual production capacity of 20,000 tons. The annual output value is expected to reach 6 billion yuan after it is completed.
Silicon carbon negative electrodes have an extended cycle life, higher energy density and better safety and environmental performance. They can be widely used in solid-state batteries, drones and new energy vehicles.
Yichang Hi-Tech Zone is building a silicon carbon negative electrode industry park to host these projects at the Baiyang Park of Yichang High-Tech Zone.
"Companies such as Yihua and Heyuan (which are already at the park) can provide us with raw materials, which helps reduce costs," Zheng said.
Li Guolong, the person in charge of Yichang Hi-Tech Merchant Investment Co. said: "At present, five silicon carbon negative electrode industry chain enterprises, such as Shenghao, Heyuan and Jiangxin, have settled in Baiyang Park. Two more are about to settle.” He added that the annual output value is expected to reach 60 billion yuan once all are put into operation.
