China Steel Chemical Corp (中碳), a subsidiary of steelmaker China Steel Corp (中鋼), yesterday said it plans to triple its mesophase graphite powder capacity this year to meet growing demand for lithium batteries used in electric buses, racing cars and storage systems for wind turbines.
The Kaohsiung-based company plans to expand its mesophase graphite powder capacity to 6,000 tonnes by next quarter from 2,000 tonnes at its factory in Pingtung County’s Fangliao Township (枋寮), allowing customers to verify its products in the second half of this year, it said.
Revenue contribution from carbon materials, including the company’s new mesophase graphite powder business and graphite blocks, is expected to increase from 10 percent of its revenue in January to November last year, China Steel Chemical said.

KEY MATERIAL
Mesophase graphite powder is a key raw material for negative electrode material used in lithium batteries.
The company’s products can help boost a battery’s capacity 1.33 times to more than 480 milliampere-hour (mAh) per gram of negative electrode material, from 360mAh, it said.
China Steel Chemical is expanding its graphite crucibles capacity to cope with increasing demand from customers, who use graphite blocks to make graphite crucibles for semiconductor companies to make silicon-carbide chips.
Customers’ lithium batteries are also used in racing cars and supercars, in addition to smart meters and uninterruptible power supply devices, it said.
The company has shipped mesophase graphite powders to customers in the US, Europe, Japan, South Korea and Thailand, it said.
MARGINS
The company’s carbon materials business delivered a lower margin of 19.3 percent compared with the corporate average of 25.4 percent during the first 11 months of last year, with the coal tar business delivering a much higher margin of 34.5 percent.
Overall revenue last year declined 20.48 percent to NT$8.32 billion (US$265.4 million) from NT$10.46 billion in 2022, it said. Pretax profit fell about 16.43 percent to NT$1.73 billion last year, compared with NT$2.07 billion the previous year, company data showed.
The company has an optimistic outlook about petrochemicals and carbon materials this year, it said last month.
CHIP HANG-UP: Surging memorychip prices would deal a blow to smartphone sales this year, potentially hindering one of MediaTek’s biggest sources of revenue MediaTek Inc (聯發科), the world’s biggest smartphone chip designer, yesterday said its new artificial intelligence (AI) chips used in data centers are to account for 20 percent of its total revenue next year, as cloud service providers race to deploy AI infrastructure to meet voracious demand. MediaTek is believed to be developing tensor processing units for Google, which are used in AI applications. While it did not confirm such reports, MediaTek said its new application-specific IC (ASIC) business would be a new growth engine for the company. It again hiked its forecast for the addressable ASIC market to US$70 billion by 2028, compared

MediaTek Inc (聯發科), the world’s biggest smartphone chip supplier, yesterday said it plans to double investment in data center-related technologies, including advanced packaging and high-speed interconnect technologies, to broaden the new business’ customer and service portfolios. The chip designer is redirecting its resources to data centers, mainly designing application-specific integrated circuits (ASIC) with artificial intelligence (AI) capabilities for cloud service providers. The data center business is forecast to lead growth in the next three years and become the company’s second-biggest revenue source, replacing chips used in smart devices, MediaTek president Joe Chen (陳冠州) told a media event in Taipei. “Three or four years
AT HIGH CAPACITY: Three-month order visibility on stable customer demand would push factory utilization to between 80 and 85 percent, Vanguard’s president said Foundry service provider Vanguard International Semiconductor Corp (世界先進) yesterday said it is unable to fully satisfy surging demand for chips used in artificial intelligence (AI) servers and data centers, amid an AI infrastructure investment boom that is crowding out production of less advanced chips. Vanguard is facing an “undersupply of chips” made using mature process technologies, due to strong demand for AI products and improving demand from customers in the commercial, industrial and auto sectors, which are digesting excess inventory to a healthier level, company chairman Fang Leuh (方略) told a virtual investors’ conference. However, Vanguard gave a more conservative view on
