Founded in 2007, Dynalink Electronic Technology Co., Ltd (DL) has developed into a premier vertical industry leader, operating as a state-of-the-art designer and manufacturer specializing in advanced power supplies, energy storage capacitors, and high-precision electrical connectors.
With an intensive investment infrastructure in material sciences, R&D, and precision automation lines, our facility is run by over 800 highly skilled personnel, including more than 200 senior technical specialists. We own the entire upstream and downstream lifecycle: from raw material formulation and electrode synthesis to structural mechanical design and complex multi-layer manufacturing.
Our components support extreme missions in aerospace, marine propulsion, high-speed rail systems, UAVs, grid-scale energy systems, and high-performance electric vehicles. We work closely with tier-1 engineering contractors globally, providing customized energy and connectivity architectures that deliver maximum durability under volatile conditions.
We solve the toughest engineering challenges in extreme environments, combining advanced material chemistry with mechanical precision.
Our supercapacitor battery architectures allow rapid recharge and deliver continuous, high-current discharge cycles, ensuring system reliability and safety during critical flight operations.
Designed for mission-critical computing, our high-speed, low-loss connectors and power management units provide zero-latency backup transitions, eliminating the risks of power fluctuations.
Our heavy-duty, IP-rated circular connectors and self-healing capacitors maintain operation under extreme vibrations, temperature fluctuations, and severe chemical exposure.
We leverage our self-developed digital simulation platform to quickly turn client specifications into physical prototypes, optimizing design cycles for custom applications.
DL continuously pushes the boundaries of chemistry and design, optimizing solid-state electrolyte structures and contact engineering to produce long-lasting energy storage components.
With massive automated production lines, we support large-scale OEM runs without sacrificing quality. Our systems guarantee strict tolerance controls for high-volume orders.
An in-depth look at performance parameters, electrode chemistry, and integration requirements for complex mission structures.
Standard energy storage configurations face a constant compromise: traditional electrostatic double-layer capacitors (EDLCs) offer virtually unlimited cycle lives and rapid power delivery, yet struggle with low energy density. Conversely, lithium-ion chemical batteries store significant energy but degrade rapidly when subjected to high discharge/charge rates and temperature extremes. Our hybrid Super Capacitor Batteries solve this issue.
By pairing high-surface-area carbon cathodes (utilizing electrostatic charge storage) with advanced lithium intercalating metal oxide anodes (utilizing faradaic electrochemical reactions), our hybrid systems deliver exceptional results. This combination offers high power density alongside reliable energy capacity, all while maintaining a cycle life that far exceeds standard lithium chemistries.
"The integration of carbon nanotubes and tailored organic electrolytes allows our OEM supercapacitor battery configurations to operate reliably across a wide temperature range (-40°C to +85°C) without runaway degradation."

| Thermal Runaway Hazard | Extremely Low | Negligible | Moderate to High |
High discharge currents require minimal internal resistance (ESR). Standard cabling and electrical interconnections can introduce contact resistance that leads to excessive heat generation, voltage drops, and system failures. That is why DL provides an integrated system solution.
By engineering high-speed transmission connectors and rugged circular couplings alongside our energy storage devices, we optimize the complete electrical path. Our 80X and VPX backplane systems use optimized contact metallurgy to maintain minimal insertion loss and low resistance, ensuring safe operation during high peak currents.
How we leverage direct supply chains, state-of-the-art material sourcing, and efficient shipping lanes to optimize costs and minimize lead times.
Based in China's advanced electronics hub, DL maintains complete control over the supply chain. We procure active carbon materials, binders, and specialty separators directly from raw chemical processors. Our in-house research facility refines these raw inputs into high-performance electrodes, bypassing intermediate processing fees.
Additionally, our on-site precision CNC machining division manufactures all components for our heavy-duty connectors, backplane shells, and structural enclosures. This vertical integration allows us to offer high quality control, trace every manufacturing step, and reduce lead times to half the industry average.
Direct supply contracts for precursor lithium formulations and high-purity carbons ensure stable pricing and consistent material quality, even during market fluctuations.
We utilize automated electrode coating, precision winding, automated hermetic seal laser welding, and high-speed multi-stage testing setups to ensure consistent cell performance.
Located near major ocean freight ports and air cargo hubs, we provide efficient global shipping options, complete with full documentation for dangerous goods compliance.
We design and manufacture our products to comply with stringent aerospace, defense, and global safety standards.
We provide localized engineering support and ensure all products comply with international regulatory frameworks.
Exporting electrical equipment and chemical storage systems globally requires compliance with regional safety frameworks. Our entire product catalog conforms to CE directives (LVD, EMC) and the latest RoHS/REACH restrictions, ensuring smooth entry into the European Union and North American markets.
Additionally, all custom battery assemblies undergo strict testing in accordance with UN38.3, IEC 62619, and UL 1973 standards. This guarantees their safety during international transport and operation in harsh settings.
"We partner with local engineering and logistics offices in North America, Europe, and the APAC region to assist our clients with import clearances, field integrations, and system diagnostics."
To reduce integration timelines, DL offers localized engineering support. Our field application teams help clients configure setups, design customized connector panels, and program BMS settings.
We maintain regional spare parts warehouses and dedicated diagnostics centers to provide fast component replacements and minimize system downtime for your operations.
