Product Series and Technical Parameters
Qingyan Electronics' supercapacitors are designed into three segmented models to meet the power and capacity requirements of different application scenarios. The detailed technical parameters are shown in the table below:
As an innovative enterprise focusing on the energy storage field, Qingyan Electronics has built a portfolio of high-performance and reliable supercapacitors based on its independently developed core dry-process preparation technology. Compared with traditional wet-process technology, the dry process fundamentally optimizes the uniformity of the electrode structure, significantly reduces interface impedance, and avoids the impact of solvent residues on capacitor lifespan. This enables the products to achieve industry-leading levels in voltage stability, capacity density, cycle life, and high-low temperature adaptability. Currently, Qingyan Electronics' supercapacitors have formed three major series: EDLC-Snap Type, EDLC-Screw Type, and HESC-Screw Type, widely serving key fields such as new energy, industrial energy conservation, and intelligent equipment, providing customers with efficient and long-lasting energy storage solutions.
Core Technological Advantages: Dry Process Empowers Outstanding Performance
The core competitiveness of Qingyan Electronics' supercapacitors stems from the independently developed dry-process electrode preparation technology, which has three key advantages over traditional wet-process technology:
Highly Stable Structure
Adopting dry calendering forming technology, the electrode material does not require solvent dissolution and drying processes. This effectively avoids issues such as uneven electrode pores and active material detachment caused by solvent volatilization. The electrode structure compactness is increased by 30%, and the interface contact resistance is reduced by 15%, ensuring voltage stability of the capacitor in high-frequency charge-discharge scenarios.
Ultra-Long Lifespan Guarantee
The dry process eliminates the corrosion risk of electrolyte caused by solvent residues. At the same time, the bonding strength between the electrode and the current collector is increased by 25%, significantly reducing electrode loss during cyclic charge-discharge. This enables the EDLC series products to achieve a cycle life of over 1,000,000 times, far exceeding the industry average.
Wide Temperature Range Adaptability
Through precise control of electrode material particle size via the dry process, the ion migration channel is optimized. The product maintains a capacity retention rate of ≥80% in a low-temperature environment of -40℃ and a leakage current of ≤5μA in a high-temperature environment of 65℃, perfectly adapting to energy storage needs under extreme working conditions.
