Expansion Strengthens Position in Lithium-Ion Battery Market

China’s Guizhou Kaijin has expanded its lithium-ion battery anode production capacity to 120,000 tonnes per year. The facility in Tongren city, Guizhou province, began operations in May 2022 with six lines producing 100,000 t/yr. Following upgrades and the installation of two additional lines, trial production for the seventh and eighth lines is set to begin by the end of July.

Kaijin’s sales performance reflects this rapid expansion. Between January and April 2025, the company sold 50,000 tonnes of anode materials, compared with just 10,000 tonnes during the same period in 2023. As a subsidiary of Guangdong Kaijin, one of China’s top five anode producers, the company strengthens its foothold in the global battery supply chain.

NEV Boom Drives Rising Demand for Anode Materials

China’s fast-growing new energy vehicle (NEV) industry is fueling strong demand for lithium-ion battery anode materials. National shipments of anode materials reached 2.12mn tonnes in 2024, up 24% from 2023. This growth aligns with rising NEV production and sales, supported by robust consumer demand and government incentives.

China produced 5.7mn NEVs from January to May 2025, a 45% increase compared with the same period in 2024. Sales also grew by 44% to 5.61mn units. As a result, overall production of power and energy storage batteries rose by 63% year-on-year to 568.1GWh during January-May, according to the China Automotive Battery Innovation Alliance (Cabir).

The Metalnomist Commentary

Guizhou Kaijin’s expansion demonstrates the strategic scaling of China’s battery materials industry in response to surging NEV demand. As global automakers diversify supply chains, Kaijin’s growth reinforces China’s dominance in anode materials. However, international competition and technology shifts, such as LFP adoption, will challenge long-term market positioning.
