Hithium Unveils the Future of Energy Storage

On June 11, 2025, Hithium, a frontrunner in energy storage technology, made headlines at the SNEC 2025 by announcing the successful mass production of the world's first kAh battery cell, the ∞Cell 1175Ah, at its manufacturing facility in Chongqing, China. This milestone marks a revolutionary step toward the widespread adoption of long-lasting energy storage solutions.

Overcoming Technical Challenges

Hithium has uniquely positioned itself to navigate the complexities associated with producing kAh battery cells by investing significantly in research and development since 2022. The company faced unprecedented challenges concerning size, process intricacy, and quality control. Its Chongqing facility implemented five groundbreaking innovations across the manufacturing process to enhance efficiency and product quality:

1. Precision Coatings: Utilization of high-precision CCD cameras has allowed Hithium to achieve a coating density variance (COV) of under 0.2%. This progression ensures stable, consistent quality across all battery cells.
2. Improved Electrode Stacking: The company has achieved a stacking alignment accuracy of 0.5 mm, increasing throughput by 35% over traditional methods.
3. Innovative Cell Structure Design: Adoption of a proprietary
