Academic Authority Empowers Intelligent Manufacturing Upgrading Lithium - Ion Battery Equipment

— Focusing on Pain Points in Large Cell Manufacturing, Building a High-Security Energy Storage Technology Foundation Lithium - Ion Battery Equipment

Ⅰ. Arrival of an Industry Giant: Academic Leadership in Industrial Practice

On June 9, Cao Yuliang, an academic giant in the energy storage field, Professor at the School of Chemistry and Molecular Sciences of Wuhan University, and Founder of Shenzhen JiaNa Energy, brought Cutting-edge research wisdom into Yixinfeng's R&D center. As an authority in sodium batteries who has been listed as a "Highly Cited Researcher" for five consecutive years, with a foundation of over 300 SCI papers published in international top journals such as Nature sub-journals, he engaged in in-depth closed-door technical discussions with Wu Songyan, Founder of Yixinfeng.

The "rust-synthesis cathode technology" pioneered by Prof. Cao's team achieves an ultra-high cycle retention rate of 93.3%, rewriting industry cost rules; his edited book Sodium Ion Batteries: Principles and Technologies is regarded as the industry "bible". This visit not only represents deep empowerment of industrial practice by academia but also authoritative recognition of Yixinfeng's technical route of "equipment defining cell safety".

Ⅱ. Addressing Pain Points: Three Key Challenges in Large Cell Manufacturing

1. Breaking Through Low-Temperature Performance: Collaborative Innovation from Electrolyte to Equipment
   Facing the industry challenge of sharply reduced energy storage efficiency in extremely cold environments of -35°C, Prof. Cao inspired Yixinfeng's development of low-temperature battery equipment with the "high-salt electrolyte self-extinguishing mechanism" published by his team in Nature Energy. The two sides deeply discussed integrating the characteristics of flame-retardant electrolytes into cell structure design, planning to achieve a 20% increase in battery capacity retention at low temperatures through equipment innovation, breaking the limitations of extreme climates on energy storage applications.
2. Cost Reduction Logic for Large-Sized Cells: Precision Equals Efficiency
   "The low cost of sodium batteries must be transformed into high energy density through structural design," Prof. Cao hit the industry's pain point—current reliance on Lithium Battery equipment leads to insufficient compaction density and uneven interface contact. Yixinfeng's displayed lamination precision technology of ±0.02mm (far exceeding the industry average of ±0.1mm) and multi-needle electrode positioning system accurately target the key to improving large cell yield. Data shows that every 0.01mm increase in precision can reduce cell costs by 3%, leveraging extreme precision for cost efficiency.
3. Balancing Safety and Scalability
   Aiming at the industry dilemma that "every 1Ah increase in capacity exponentially raises thermal runaway risk", Prof. Cao's proposed concept of "bionic micro-channel thermal 疏导 (疏导)" resonates technically with Yixinfeng's multi-dimensional thermal management framework in module lamination machines. Yixinfeng's self-developed laser die-cutting and slitting integrated machine achieves class 10,000 cleanliness standards for dust control, preventing thermal propagation caused by micro-shorts from the source and building a safety line for large cell mass production.

Ⅲ. Yixinfeng's Solution: Overcoming Sodium Battery Industrialization Barriers with Millimeter-Level Intelligent Manufacturing

In Yixinfeng's intelligent equipment workshop, the world's first "sodium battery large cell intelligent lamination production line" became the focus. Prof. Cao witnessed Yixinfeng's technical strength on-site:

• Laser die-cutting, winding, and flattening integrated machine: The innovative plum-blossom pole piece cutting process improves electrolyte distribution uniformity by 40%, effectively extending battery cycle life;
• 
• Module lamination integrated machine: Single-station efficiency exceeds traditional three-station equipment, with floor space reduced by 35%, helping reduce cell costs by 30%;
• ±0.02mm ultra-precision lamination: Breaks through the 350Wh/L bottleneck of sodium battery volume energy density, laying a solid foundation for mass production of Prof. Cao's team's "hard carbon-Prussian blue" system.

"Equipment precision is the lifeline of sodium battery industrialization," Prof. Cao's on-site conclusion highly confirms the forward-looking and value of Yixinfeng's strategy of "defining cell safety through equipment".

Ⅳ. Integration of Industry and Research: From Technical Resonance to Practical Implementation

Based on this in-depth exchange, both sides reached practical cooperation directions, opening a new chapter of industry-academia-research collaborative innovation:

• Process adaptability research: Transplanting Prof. Cao Yuliang's team's military-grade power thermal blocking technology into Yixinfeng's equipment system, jointly building a large cell safety testing platform to accelerate the transformation of research results into industrial applications;
• Industrialization efficiency improvement: Relying on Yixinfeng's 186 core patents and rich experience of 98.7% equipment availability, developing a process parameter database for special sodium battery equipment to provide standardized solutions for the industry;
• Ecological chain collaboration demonstration: Exploring the application adaptation of Yixinfeng's equipment in JiaNa Energy's sodium battery production line, promoting the formation of a technical closed-loop of "equipment-materials-cells" to improve the sodium battery industry ecosystem.

Let Academic Light Illuminate the Path of Intelligent Manufacturing

When the electrochemical wisdom of Luojia Mountain deeply merges with the precision intelligent manufacturing of Dongguan workshops, a revolution in energy storage safety and efficiency has already begun. Yixinfeng will uphold the ultimate pursuit of ±0.02mm, practice the mission of "equipment innovation empowering battery evolution", build a safety great wall in square lamination, define the energy future in millimeter precision, and inject strong momentum into China's energy storage industry moving towards the world's forefront.
