Product Characteristics
Our products demonstrate significant competitive advantages and have received unanimous acclaim from a broad customer base. The company has established partnerships with SF Express, JD.com, and China Post, achieving in-depth collaboration and flexible operations in "last-mile" logistics transportation for selected cities.
Cost Benefits
The cylindrical full tab cell IFR32140 (LFP) developed by our company features higher single-cell energy density and lower manufacturing costs compared to traditional cylindrical cells.
Process Innovations
Advanced full-tab flattening technology for electrodes and laser welding processes for current collectors significantly reduce internal resistance while enhancing rate capability.
Electrolyte Design
The optimized electrolyte formula incorporates wide-temperature-range additives for extreme environments and specialized film-forming additives to extend cycle life. These innovations substantially improve the cell's overall high/low-temperature performance and cycling stability.
Key Product Technical Performance
This product is a high-energy-density power and energy storage battery cell, featuring an overall height of 140mm and a diameter of 33mm. Structurally, it employs a full-tab winding and flattening design, effectively resolving the poor rate capability inherent to traditional cylindrical cells while significantly reducing internal resistance and enhancing thermal dissipation within the cell. The positive terminal cap integrates CID (Current Interrupt Device) activation and explosion-proof technologies, substantially improving safety and reliability.
