On August 22, 2025, HiTHIUM hosted a shipment milestone ceremony at its Chongqing manufacturing facility, marking the delivery of more than 100 gigawatt-hours (GWh) of energy storage products since late 2021. Over this period, the company has advanced from a global ranking of fifth in 2023 to third in 2024, and entered the top two in the first half of 2025, reflecting sustained growth in the energy storage sector.
Through a vertically integrated research and development approach—spanning materials design to recycling—HiTHIUM has introduced innovations that improve cell safety, efficiency, consistency, and lifecycle performance while reducing costs. The company applies predictive modeling to adjust production parameters based on material inputs, maintains defect rates at parts-per-billion levels via micron-scale precision manufacturing, and employs generative artificial intelligence and Internet of Things technologies for end-to-end process traceability.
To support system deployment and operation, HiTHIUM has established a comprehensive lifecycle service portfolio covering project planning, customization, delivery, commissioning, and ongoing maintenance. Its network of service hubs and local teams across more than 20 countries provides customers with rapid technical assistance and performance monitoring.
Safety and reliability are central to the firm’s project execution in diverse environments such as high-altitude plateaus, deserts, permafrost regions, and extreme heat zones. HiTHIUM conducts rigorous testing protocols throughout manufacturing, transportation, use, and recycling phases. In early 2025, under observation by UL Solutions, the company completed the industry’s first large-scale open-door fire test on its ∞Block 5 MWh battery energy storage system, demonstrating resilience under severe conditions.
As part of its push into long-duration storage, HiTHIUM’s Chongqing base recently commissioned fourth-generation high-efficiency production lines. In June, the facility rolled out the ∞Cell 1175 Ah, the world’s first megawatt-hour–class long-duration cell. The related ∞Power 6.25 MWh, 4-hour system is scheduled for global deployment in the fourth quarter of 2025 and is positioned to serve as a benchmark for extended-duration installations.
Looking ahead, HiTHIUM plans to focus on long-duration energy storage solutions backed by ongoing innovation and a global strategic footprint, contributing to the broader transition to high-quality green energy.
