Chinese energy storage manufacturer Hithium said on October 15 that its cumulative battery shipments had exceeded 200 GWh, marking a sharp acceleration in growth since the company began commercial deliveries in late 2021. The milestone was announced at its manufacturing site in Chongqing, southwestern China.
The 200 GWh figure represents cumulative shipments, rather than annual manufacturing capacity or the amount of battery storage installed and operating worldwide. Hithium reached its first 100 GWh in August 2025, nearly four years after initial shipments, and added another 100 GWh in approximately 14 months.
Founded in Xiamen in 2019, Hithium shipped 35.1 GWh of energy storage batteries in 2024, according to figures disclosed in its earlier Hong Kong listing application. Its global ranking rose from fifth in 2023 to third in 2024 and second in 2025, according to the company. InfoLink Consulting also ranked Hithium second behind CATL in global energy storage cell shipments in the first half of 2026.
Hithium’s production network centers on three Chinese sites. Its Xiamen headquarters houses R&D and battery manufacturing, with reported annual cell capacity of 45 GWh in 2025. The Chongqing complex has a planned annual capacity of 56 GWh of battery cells. The site received World Economic Forum Lighthouse Factory recognition in January 2026 and is ramping up dedicated lines for large-format long-duration storage cells.
Its newer plant in Heze, Shandong province, began mass production in August and has a planned annual capacity of 30 GWh of storage cells and 20 GWh of integrated storage systems. The facility made its first overseas shipments in September. These capacity figures cover different production stages and include planned output, rather than a verified total of currently available cell capacity.
Overseas, Hithium began shipping systems from its Mesquite, Texas, assembly plant in August 2025. The facility is designed to assemble 10 GWh of battery modules and systems annually, rather than manufacturing cells. The company has also agreed to develop a roughly €400 million battery cell and system plant in Navarre, Spain, with production targeted for 2027.
Hithium is focusing its next expansion on lithium iron phosphate products tailored to four-hour and longer storage applications. Its 1,175 Ah cells are designed for four-hour systems, while the 1,300 Ah format targets eight-hour applications.
“Our orders for long-duration storage now extend through the end of 2027,” co-founder and CEO Jason Wang told ESS News at an October 15 media briefing. The company did not disclose the contracted volume.
The milestone reflects both Hithium’s rapid scaling and a broader surge in utility-scale battery demand. It also supplies the Swiss-headquartered Turkish BESS manufacturer Maxxen.
