August 22, Chongqing, China - On August 22, 2025, HiTHIUM, a leading global energy storage technology company, successfully held the “HiTHIUM 100GWh Shipment Milestone Ceremony” at its Chongqing manufacturing base. Since shipments began at the end of 2021, the company has built core competitiveness through innovation, service, safety, and global presence. Having surpassed 100GWh in cumulative shipments, HiTHIUM has also climbed the global rankings—from fifth in 2023 to third in 2024, and Top 2 in the first half of 2025—setting a benchmark for high-quality growth in energy storage.
Focused Strategy, Driving End-to-End Innovation
HiTHIUM’s 100GWh milestone reflects its differentiated strategy of focusing solely on energy storage. As the only GWh-scale lithium-ion battery maker dedicated to this field, the company has built end-to-end capabilities from materials to systems, enabling it to anticipate needs and launch industry-first technologies. Milestones include pioneering long-duration storage in 2022, the world’s first kAh battery and ∞Power 6.25 MWh BESS in 2023, and in 2024, the ∞Cell 587Ah and ∞Cell N162Ah, the first sodium-ion battery for utility-scale energy storage.
With most already in or nearing mass production, HiTHIUM continues to lead by moving early in design, R&D, production, and delivery—turning advanced technologies into customer value. This stems from deep insight into industry trends: long-duration storage is becoming a key enabler of the energy transition, grid storage is driving large-scale sodium-ion adoption, and the integration of innovation with mass production is essential to overcome scale barriers and achieve sustainable growth.
Lead with Innovation, Forge Advanced Manufacturing
Technological innovation is HiTHIUM’s core growth driver. Through in-house R&D, it has built an end-to-end system from materials to recycling, achieving breakthroughs in safety, efficiency, consistency, lifecycle, and cost. On the manufacturing front, HiTHIUM leverages extreme and advanced processes with system integration to enhance quality and efficiency:
· Using industry-leading predictive models to recommend downstream production parameters based on incoming materials, ensuring consistency in cell performance;
· Achieving PPB-level defect rates through micron-level precision and zero-defect management;
· Using Gen AI and IoT for full-process traceability and optimal efficiency.
Delivering Excellence in Service, Earning Global Trust
The delivery, commissioning, and operation of energy storage systems mark the starting point of customer value. HiTHIUM has built a lifecycle service system—covering planning, customization, delivery, and O&M—to ensure reliable performance and strong customer experience.
HiTHIUM’s global service network spans 20+ countries and regions, offering customized packages and flexible models. Local teams and service hubs provide rapid, measurable support.
Safety and Reliability as the Foundation for Lifecycle Stability
Behind the 100GWh milestone is the safe operation of HiTHIUM’s global projects. From plateaus and deserts to permafrost and heat, the company applies rigorous testing and full-lifecycle safety management—covering manufacturing, transport, use, and recycling. Multi-level protections across materials, cells, modules, and systems ensure long-term stability in demanding environments worldwide.
HiTHIUM’s batteries and systems have proven resilient in extreme conditions. In 2025, under the witness of UL Solutions, the company carried out the world’s first all open-door large-scale fire test on its ∞Block 5MWh BESS, confirming HiTHIUM’s reliability under the harshest scenarios.
Driving Shipments to New Heights with Long-Duration Energy Storage
At the ceremony, HiTHIUM’s Chongqing manufacturing base drew wide attention. As its strategic hub in Southwest China, the base features fourth-generation high-efficiency lines. In June, the ∞Cell 1175Ah—the world’s first MWh-class long-duration storage cell—rolled off the line. The ∞Power 6.25MWh 4h BESS built on this cell is scheduled for global project delivery in Q4 2025 and is expected to become a benchmark in long-duration storage, supporting the global transition to green energy.
For HiTHIUM, the 100GWh milestone is a new starting point. As the market shifts toward long-duration solutions, the company will stay focused on energy storage, driven by innovation and global strategy, delivering the “HiTHIUM Solution” to support the transition to high-quality green energy.
