Shengquan Group invested 2.5 billion yuan to build 100,000 tons of bio-based hard carbon anode materials

On December 16, Jinan Shengquan Group Co., Ltd. announced that it will invest 2.480 billion yuan to build a bio-based hard carbon anode material project with an annual output of 100,000 tons. Shengquan Group expects that after the project is completed and put into operation, it can produce 100,000 tons/year of hard carbon anode materials, 150,000 tons/year of cellulose pulp, 10,000 tons/year of nanocellulose pulp, 40,000 tons/year of nanocellulose, 12,000 tons/year of furfural, 10,500 tons/year of acetic acid, and 5,000 tons/year of potash salt. The project will further extend the company's industrial chain, optimize the company's product structure, and help the company find new business growth points.

Hard carbon is currently the mainstream anode material for sodium batteries, and it is also an important constraint for the scale of the sodium battery industry. There are various production routes for hard carbon anodes, including biomass-based, fossil-fuel-based and synthetic polymer-based, and the various routes and costs are different, especially the biomass-based raw materials are more extensive.

Bio-based hard carbon anode materials, as one of the negative electrode materials, have comparative advantages over other materials in terms of safety, cycle life, production cost and other comprehensive indicators.

The project is located in Jinan Diao Town Chemical Industrial Park, mainly to build process production equipment, storage and transportation facilities, public works and auxiliary facilities, and service facilities with an annual output of 100,000 tons of bio-based hard carbon anode material project. The total investment of the project was 2.48 billion yuan. Among them, the construction investment is 2.237 billion yuan, and the bottom working capital is 144 million yuan. The project is financed by the company's own funds and bank loans. Of the construction investment, 1.637 billion yuan came from bank loans, accounting for 66.01% of the total investment. The project construction period is 18 months. The project has obtained the filing certificate on December 16, 2022, and it is still necessary to go through the approval procedures for project safety and environmental protection with the relevant administrative department as required.

This project is based on Shengquan biological solvent method biomass refining technology, superimposed biomass graphene, carbon anode and other key carbon material preparation technology developed. At present, hard carbon precursor biochar materials are about to achieve mass production, but hard carbon anode materials have not yet been mass-produced. Shengquan Group has more than 30 R&D teams of bio-based hard carbon, including 5 doctors and 15 masters.
