China’s Ganfeng Lithium, the world’s largest producer of lithium metal, is envisioning an “explosive growth” in the global energy storage system (ESS) market in 2026, spurred by higher prices of the key battery material and buoyant demand for renewable energy infrastructure.

Executives including president Wang Xiaoshen told an investors’ conference on Tuesday that the global decarbonisation drive had created a strong and sustainable trajectory for Ganfeng, which swung from loss to profit last year as lithium prices climbed.

“The ESS sector has entered a period of explosive growth, and this trend is expected to continue into 2026,” executives said in a filing to the Shenzhen Stock Exchange. “At the same time, AI [artificial intelligence] computing and data centres, the new power consumption scenarios, are driving a constant increase in demand for ESS.”

The upbeat forecast by Ganfeng, which supplies lithium to the world’s major carmakers from Tesla to BMW, came after analysts predicted that mainland China would maintain its dominance in the global ESS battery market.

Ganfeng’s Hong Kong-listed shares slumped 4.7 per cent to HK$69.30 on Wednesday morning while its Shenzhen-listed shares dropped 1.4 per cent to 77.28 yuan.

In 2025, Ganfeng posted net profits of 1.61 billion yuan (US$233.8 million), compared with net losses of 2.1 billion yuan a year earlier.
