2025-06-14 | Calvin

June 11, 2025 - At SNEC 2025, the premier International Photovoltaic Power Generation and Smart Energy Conference & Exhibition, HiTHIUM, a global leader in energy storage technology, marked a historic milestone with the successful mass production of the world's first kilowatt-hour (kAh) battery cell - the ∞Cell 1175Ah. This breakthrough achievement at HiTHIUM's Chongqing manufacturing base signals a new era in scalable long-duration energy storage solutions.

Five Technological Breakthroughs Enabling kAh Battery Production

Anticipating the long-duration energy storage revolution, HiTHIUM initiated kAh battery R&D in 2022, overcoming significant technical challenges through innovations across the entire manufacturing chain:

• Precision Coating Technology: Achieved coating mass density COV <0.2% with high-precision CCD camera inspection
• Advanced Stacking Process: 0.5mm alignment accuracy at 0.1625 seconds per sheet, increasing throughput by 35%
• Patented Cell Design: Proprietary "integrated 3D airflow top cover" structure with dedicated automation equipment
• Enhanced Manufacturing Efficiency: 45% improvement in back-end processes through high-efficiency baking and 1.2MPa high-pressure electrolyte filling
• Superior Packaging Quality: Flexible lamination roller system eliminates wrinkling and bubbling in ultra-large cells

Redefining Energy Storage Safety Standards

Dr. Xiaoxiao Liu, HiTHIUM's product safety expert, emphasized the company's multi-level safety architecture that spans cell, module, and system levels:

• Cell Level: Advanced electrolyte formulation creates high-temperature-resistant SEI/CEI layers
• Pack Level: Dual-mode thermal protection with flame-retardant top cover
• BMS Level: Multimodal early warning algorithms and redundant control technologies
• System Level: Multi-layer fire-resistant materials with intelligent detection and suppression

Global Recognition and Market Expansion

The ∞Cell 1175Ah has received prestigious UL 1973 and UL 9540A certifications from UL Solutions, validating its compliance with global safety standards and facilitating entry into the North American market. HiTHIUM has also formed a strategic partnership with Israel's El-Mor to develop its first long-duration energy storage project in Romania.

As a top 3 global energy storage battery provider, HiTHIUM continues to lead industry innovation. The ∞Cell 1175Ah establishes new benchmarks for large-capacity energy storage, positioning HiTHIUM at the forefront of the long-duration energy storage revolution.
