Key Highlights
Hunan Qixian New Material Technology (湖南省齐贤新材料科技有限公司), a Chinese porous carbon producer, has issued a formal price increase notice to customers, announcing a blanket 20% price hike across its entire porous carbon product range, effective 1 April 2026.
The company cited significant increases in raw material and energy costs as the primary driver. The new pricing will apply to all orders signed from 1 April onwards. Existing contracts that have been signed but not yet fully executed will be honoured at the original agreed price and are not affected by the adjustment.
Porous carbon is a critical precursor material in the production of silicon-carbon anode materials, where it serves as the structural scaffold into which silicon is deposited (typically via chemical vapour deposition). As silicon-carbon anode adoption accelerates in the Chinese battery supply chain, demand for high-quality porous carbon feedstock has been tightening. A 20% price increase from a supplier like Qixian signals real cost pressure at the upstream end of the silicon-carbon value chain, and is worth watching as a potential leading indicator for broader silicon-carbon anode pricing trends.
Note: All CNY figures converted to USD at an approximate rate of 1 USD = 6.89 CNY as of 21 March 2026.
