Explore our foundational portfolio of components designed for integration into demanding industrial electrical architectures.
Modern electrical engineering projects are increasingly faced with a critical design challenge: finding energy storage systems that balance the energy reserves of chemical batteries with the immediate power delivery and long cycle lives of electrostatic double-layer capacitors (EDLCs). Lithium-ion supercapacitors (also termed Lithium-Ion Capacitors, or LICs) emerge as the hybrid solution to close this technology gap.
As a leading ODM Li Ion Supercapacitor Manufacturer & Supplier, Dynalink Electronic Technology Co., Ltd designs customized electrochemical setups to meet demanding industrial specifications. We leverage advanced materials engineering to manufacture LICs that utilize an asymmetric electrode system. The positive electrode consists of activated carbon (storing energy through electrostatic double-layer capacitance), while the negative electrode features a lithium-doped carbon substrate (storing energy faradaically through intercalation). This hybrid chemistry yields substantial operational improvements over traditional capacitor types.
By using pre-doped lithium intercalation anodes, our LIC solutions deliver energy densities up to four times higher than conventional EDLCs, reducing the total footprint of capacitor modules in compact designs.
Capable of enduring over 50,000 to 100,000 charge-discharge cycles without significant capacitance fade, minimizing total lifecycle costs and replacement operations in automated systems.
Unlike standard chemical cells, our customized supercapacitors operate reliably under severe temperature conditions ranging from -40°C up to +85°C, ensuring stability in extreme industrial environments.

We create a positive and united working atmosphere, attach great importance to the growth and development of employees, and provide them with broad career advancement opportunities and a complete training system.
Focusing on the fields of batteries, capacitors, and connectors, we use innovation as our spear, making every effort to overcome the technical bottlenecks of solid-state batteries, break through the upper limit of capacitor energy density, and develop high-precision and low-loss connectors.
Industrial procurement teams struggle with component longevity, safety in extreme operations, and supply stability. The transition to green logistics (e.g., AGVs, electric warehouse systems) requires reliable high-power cells capable of fast charging to minimize charging downtime.
With smart cities and 5G base stations expanding worldwide, grid operators require robust energy backup units. LICs serve as active shock absorbers against surge voltages and deliver instant energy reserve for wireless transmitters.
Exporting high-tech power devices demands alignment with global green acts. Dynalink's production processes ensure compliance with international hazardous substance policies (RoHS, REACH) and transport safety protocols (UN38.3).
Dynalink is investing in solid-state electrolytes and advanced graphene matrices to push the limits of LIC chemistry. Our technical roadmap aims to boost the energy density of our custom supercapacitors to over 60 Wh/kg by 2026, while maintaining a peak discharge capability of 150C. These breakthroughs will support applications in regenerative transport grids, automated medical equipment, and deep-sea exploration vessels.
