HiTHIUM Crosses 100GWh Shipments, Climbs to Global Top 2 in Energy Storage

HiTHIUM, a global energy storage technology company, held the "HiTHIUM 100GWh Shipment Milestone Ceremony" at its Chongqing manufacturing base on August 22, 2025.    

HiTHIUM, since shipments began at the end of 2021, has built core competitiveness through innovation, service, safety, and global presence. The company, while sharing these details in a press release, mentioned, “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.”

 HiTHIUM has built its industry leading position on key innovations and long term planning. These have included manufacturing innovations like-

-Breakthrough in wide-width thick coating precision: Achieved a coating mass density COV of less than 0.2%, with online inspection through high-precision CCD cameras, ensuring consistent and stable product quality.

• Enhanced efficiency in large-electrode stacking: Reached 0.5mm alignment accuracy and 0.1625 seconds per sheet, increasing stacking throughput by 35% compared to conventional processes.

• Original cell structure design: Introduced a proprietary "integrated 3D airflow top cover" structure; dedicated automation equipment ensures manufacturing stability and structural strength of large-size components—breaking industry bottlenecks.

• Improved back-end cell manufacturing efficiency: Developed high-efficiency baking, 1.2MPa high-pressure isostatic electrolyte filling, and high-rate formation and grading processes, boosting back-end manufacturing efficiency by 45%.

• Greater consistency in Cell Wrapping: Introduced a highly compatible flexible lamination roller system to effectively solve industry-wide issues such as wrinkling and bubbling in ultra-large cell packaging.

HiTHIUM's batteries and systems have proven resilient in extreme conditions. The company explained, "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 a hub in Southwest China, HiTHIUM's base features fourth-generation high-efficiency lines.

Explaining the company's growth, it explained, "In June, the Lithium based ∞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."

As the market shifts toward long-duration solutions, the company said it aims to stay focused on energy storage, driven by innovation and global strategy, delivering the "HiTHIUM Solution" to support the transition to high-quality green energy.
