Guibao silicon-carbon anode capacity expands with Sichuan second phase

Chengdu Guibao Science

Guibao silicon-carbon anode capacity expands as the firm builds a second phase in Sichuan. The Meishan plant adds 3,000 t per year by December 2025. The first 1,000 t per year phase started in April 2023. Guibao silicon-carbon anode capacity could reach 11,000 t per year with phase three. However, the 7,000 t per year third phase depends on market conditions.

Timeline, scale, and technology

Site construction on phase two began in September 2024. Commissioning is targeted by end-December 2025, pending qualification. Guibao remains Asia’s largest high-end silicone sealant producer. It operates 370,000 t per year of sealant capacity. Therefore, cashflow supports capital spending and start-up risk.

Silicon-carbon anodes promise far higher specific capacity than graphite. Theoretical capacity reaches about 4,200 mAh per gram. This is roughly ten times typical graphite anode capacity. However, swelling and cycle life require careful design and binders. As a result, customer qualification remains the pacing item.

Competitive landscape and demand outlook

Industry demand for silicon anodes could reach 100,000 tonnes by 2030. Large cylindrical cells and high-nickel prismatic formats drive growth. Peer capacity is also rising across China. Beijing Lirr backed a 10,000 t per year Hubei project for 2025. Putailai started trial production in Anhui at 12,100 t per year. That includes 10,000 t silicon-carbon and 2,100 t silicon oxide lines.

Guibao silicon-carbon anode capacity positions the firm for EV and storage demand. Meanwhile, phase three offers optionality if orders accelerate. Therefore, execution must balance cost, yield, and OEM timelines.

The Metalnomist Commentary

Guibao’s staged build limits risk while capturing early silicon-anode adoption. Watch qualification wins with leading cell makers and swelling mitigation progress. Pricing and graphite substitution rates will determine margin durability.

China Anode Material Production Cuts Deepen as Putailai Slows Output

China Anode Material

China anode material production cuts intensified in 2024 as Shanghai Putailai New Energy reduced both output and sales due to oversupply and price pressure. The firm’s production dropped 18% to 136,707 tonnes, while sales declined 15% to 132,311 tonnes compared to 2023. The decline underscores the challenges faced by China’s battery material producers amid a saturated market.

Delays and Terminations Amid Market Imbalance

Putailai postponed the launch of its Sichuan plant’s first phase due to weak anode prices and funding constraints. Originally slated for December 2024, the 100,000 t/yr capacity line began operation in February. The second phase, also with 100,000 t/yr capacity, is now expected to come online by late 2026. Meanwhile, the company canceled its planned Swedish plant after failing to secure government approval.

Oversupply Challenges China’s Battery Sector

Despite strong EV sector growth, China’s anode material production cuts highlight growing pains in the supply chain. In 2024, China’s production capacity reached 3.5mn t/yr, but only 2.12mn tonnes were produced. Domestic demand stood at 1.83mn tonnes, according to ICC Sino, leaving a large volume of underutilized capacity.

The Metalnomist Commentary

China anode material production cuts reflect deeper structural issues in the battery materials market. Without pricing recovery or export diversification, producers like Putailai may face further consolidation or capacity rationalization.

Putailai Cuts Anode Output and Sales in 2024 Amid Oversupply and Weak Prices

Putailai

China’s Anode Market Faces Pressure as Capacity Surpasses Demand

Shanghai Putailai New Energy, a major Chinese new material producer, sharply reduced its anode material output and sales in 2024.

The decline reflects intensified price competition and ongoing oversupply in China’s battery materials sector.

Putailai produced 136,707 tons of anode materials in 2024, down 18% from 166,370 tons in 2023.

Sales also dropped by 15%, falling to 132,311 tons from the previous 155,317 tons.

This reduction comes as China's domestic anode demand totaled 1.83 million tons in 2024.

In contrast, the country’s annual production capacity reached 3.5 million tons, with actual output hitting 2.12 million tons.

Investment Delays and Project Cancellations Reflect Market Strain

Putailai postponed the first-phase launch of its Sichuan anode material plant to February 2025.

The facility, with a design capacity of 100,000 tons/year, was delayed due to low prices and funding shortages.

The plant's second phase, also targeting 100,000 tons/year, remains under construction.

Company officials plan to begin operations by the end of 2026, depending on market recovery.

Additionally, Putailai terminated its Swedish anode project in Sundsvall in December 2024.

The cancellation followed the Swedish government’s refusal to approve the project.

With China’s anode capacity significantly exceeding demand, many producers now face financial pressure and delayed expansion plans.

China's Putailai Cancels Sweden Battery Anode Project Amid Regulatory Hurdles

Shanghai Putailai

Chinese battery anode material manufacturer Shanghai Putailai has announced the termination of its planned battery anode material project in Sundsvall, Sweden, after failing to secure approval from the Swedish government. The decision, disclosed on December 19, follows extensive regulatory reviews and negotiations regarding investment conditions.

The project, initially designed to have a production capacity of 100,000 tonnes per year (t/yr), was expected to roll out in two phases: 50,000 t/yr by 2025, followed by another 50,000 t/yr by late 2026 or early 2027. Putailai had earmarked a maximum investment of 15.7 billion Swedish kronor ($1.4 billion) for the venture, which was part of its broader strategy to expand outside of China.

Regulatory Hurdles and Project Termination

Putailai’s foreign direct investment (FDI) declaration was submitted to Sweden’s Strategic Products Supervision Bureau in February 2024, with an official review beginning in June 2024. However, on December 3, the Swedish government imposed conditions regarding equity control, management composition, intellectual property rights, and corporate supervision for Putailai’s Swedish subsidiary, Zichen Sweden.

After failing to reach an agreement on these terms, Sweden ultimately rejected Putailai’s investment application, though specific reasons were not disclosed. The company had already invested 14 million yuan ($1.9 million) in a feasibility study, though it noted that this cost would not impact its operations.

Expanding Anode Production in China Amid Western Setbacks

Despite the setback in Sweden, Putailai remains committed to increasing its anode material production capacity. The company reported 68,197 tonnes of anode material sales in H1 2024, marking a 24% year-on-year increase. It currently operates 150,000 t/yr of total capacity and is constructing an additional 100,000 t/yr plant in Qionglai, Sichuan province, set to launch by the end of December.

Several Chinese battery material firms, including Shanshan, have sought expansion into Europe, with Shanshan planning a 100,000 t/yr anode production complex in Finland to cater to overseas demand. However, geopolitical uncertainties and economic challenges have created obstacles for Chinese firms seeking foreign investments and partnerships.

China's Zichen Expands Anode Production Capacity Amid Market Fluctuations

Sichuan Zichen Technology

Sichuan Zichen Technology, a key player in the Chinese anode materials sector and a subsidiary of Shanghai Putailai, is ramping up production capabilities with the ongoing construction of its new facility in Sichuan province. The expansion is poised to enhance the company's anode material output significantly, aligning with the growing demands of the new energy vehicle (NEV) industry.

Major Expansion in Sichuan

The latest phase of Zichen’s production complex in Qionglai city includes a second stage that will add 100,000 tons per year to the existing capacity. Construction is set to wrap up by the end of this year, complementing the first phase that began operations in July with a similar output. By the end of 2025, the company expects to commission a third phase, adding another 80,000 tons annually, bringing the total design capacity to 280,000 tons per year.

Despite these ambitious expansions, Zichen's parent company, Putailai, has experienced a slight decline in sales, with 66,992 tons sold in the first half of the year—down 1.8% from 68,197 tons during the same period last year. The backdrop of this slowdown is a significant drop in graphite flake prices, which have hit a nearly six-year low, attributed to decreased anode prices stemming from slower growth in the NEV market.

Nevertheless, the NEV sector in China continues its upward trajectory, with production soaring by 32% year-over-year to 8.316 million units from January to September, while sales surged by 33% to 8.32 million during the same timeframe, according to the China Association of Automobile Manufacturers (CAAM).
