"Intelligent" electrolyte
By rationally designing and regulating additive and solvation structure, we design an "intelligent" lithium-ion electrolyte. Through artificial intervention and precise optimization of the interface film, the micro-damage of materials is accurately identified, which fundamentally improves the cycle life of battery cells.
High-Stability Low-Lithium-Loss Graphite
Precision regulation of precursors and particle structure minimizes graphite surface defects and enhances structural stability, cutting initial lithium loss while building a robust SEI film. This drastically reduces active lithium consumption during cycling and solidifies the foundation of cell cycle performance.
High-Structural-Stability Cathode
Developing innovative multi-scale nanoparticles strategy and low-defect regulation technology, we fundamentally mitigate particle cracking and boost structural stability, significantly improving cycle life.
High thermal stability electrode materials
Cathode materials: By reconstructing safety boundaries based on first-principles, technologies for multi-element doping, ionic conductor coating, and particle size control of lithium iron phosphate (LFP) were developed.
Anode materials: A synergistic regulation technology involving “graphitization degree, surface defect engineering, and multi-scale grains” was developed, which simultaneously improves the service life and safety characteristics of the battery.
High thermal stability ceramic-coated separator
Ceramic-coated separator: Employs a thermal stability ceramic-coated separator featuring low-temperature pore closing and high-temperature rupture. This addresses the issue of poor thermal stability in conventional separators, raises the critical temperature for thermal runaway in the cell, reduces heat generation from crosstalk reactions, and enhances the intrinsic safety performance of the cell.
Three-Dimensional Air Channels
To ensure effective pressure and gas management, three-dimensional air channels are integrated to create smooth and unobstructed internal gas flow pathways. Combined with advanced venting technology, this design enables rapid pressure release, effectively preventing pressure buildup and enhancing overall cell safety.
High Capacity Consistency
Designed to ensure system-level reliability, the ∞Cell 1175Ah is the world’s first kAh-level ESS cell, delivering ultra-high capacity while maintaining exceptional engineering consistency. Cell to cell OCV consistency has been improved to under 3‰ variation, leading to improved Capacity consistency performance that of cell. The number of parallel-connected cells in the system has been reduced by 73% compared to the Cell 314Ah , substantially enhancing system performance consistency.
Lower Self-discharge
To maintain long-term consistency across large-format cells, a full-tab electrode stacking process is applied to fundamentally reduce the generation of potential particles.
Improved Electrode Interface Performance
By integrating full-tab electrode stacking, specialized separator coatings, and vacuum-assisted fixture formation, uneven mechanical stress associated with traditional electrode winding is effectively eliminated. This significantly improves SEI interface stability, ensuring superior long-term cycling consistency across cells and reinforcing the robustness of our lithium-ion battery technology at scale.
World’s First 1000+Ah
Energy Storage Battery and System
Engineered for system-level cost optimization, the ∞Cell 1175Ah is the world's first 1000+Ah energy storage battery and system solution. Compared to conventional 314Ah cells, the cost per Wh is reduced by 7.5%, while balance-of-system (non-cell) costs are lowered by up to 30%. This system-wide cost advantage is a direct result of HiTHIUM energy storage technology designed for large-format, high-efficiency ESS applications.
Ultra-thick electrode technology
The ultra-thick electrode technology is based on the synergistic optimization of gradient electrodes and anode/cathode formulations, effectively addressing the manufacturing process challenges and performance limitations associated with ultra-thick electrodes. The ∞Cell 1300Ah, which utilizes ultra-thick electrode technology, achieves a significant increase in electrode thickness compared to a standard 314Ah battery, resulting in a cost reduction of over 50% for power components such as current collector foils.
Smart Manufacturing Production Line
HiTHIUM’s fourth-generation high-efficiency lithium battery smart manufacturing production line integrates new technologies, including MES, 5G, and artificial intelligence. Compared to the third generation, production efficiency has increased by 30%, automation levels by 26%, and manufacturing costs have been reduced by 25%. This vertically integrated manufacturing capability strengthens product consistency, scalability, and cost competitiveness, demonstrating the maturity of our lithium battery technology at an industrial scale.
HiTHIUM is driven by innovation, focusing on cutting-edge technologies in materials, batteries, systems, processes, and controls.
With four dedicated research institutes, over 1,000 R&D experts, and more than 4,300 global patents,
HiTHIUM turns advanced technology into practical, scalable solutions.
All HiTHIUM technologies are thoroughly tested by internationally accredited laboratories such as
TÜV Rheinland and CNAS, and supported by ISO-certified management systems.
This allows us to deliver safe, reliable, and proven energy storage solutions for real-world applications.
