Explore our first tier of advanced battery packs, electrochemical cells, and customized energy solutions designed for robust industrial integration.
Fujian SK Battery Co., Ltd. was established in 2021 and is located in Fujian, the center of China's new energy industry. Benefiting from convenient transportation and comprehensive supply chain resources, we specialize in Ni-MH batteries, Ni-Cd batteries, lithium iron phosphate batteries, ternary lithium batteries, and sodium-ion batteries, providing battery solutions for emergency lighting, solar lights, wireless communication, and smart home systems. With deep expertise in battery application scenarios, we focus on solving core problems customers encounter during usage, offering professional technical support and services, as well as customized battery solutions to help clients achieve higher efficiency and greater value.
Modern industrial energy systems demand conflicting attributes: ultra-high energy density for long runtimes and extreme power density for transient spikes. Traditionally, battery manufacturers selected chemical systems that prioritized one over the other. The rise of hybrid systems—combining electrochemical storage with electrostatic double-layer capacitors (EDLCs) or lithium-ion capacitors (LICs)—bridges this gap.
Under the technical leadership of Fujian SK Battery Co., Ltd., we configure hybrid energy systems that place ultra-capacitors in parallel with chemical storage cells (such as our high-performance Sodium-ion and LiFePO4 lines). During peak current requirements, the ultra-capacitor discharges instantaneously, preventing voltage sag and reducing structural thermal stress within the chemical battery. This results in system lifespans extended by up to 300%.
By operating inside the Fujian new energy corridor, our research and production encompass a multi-chemistry roadmap. Our systems balance various distinct technologies:
Custom power solutions cannot rely on a one-size-fits-all battery chemistry. The integration demands tailored physical, thermal, and management layers. Our specialized solutions cater to critical sectors globally:
For instance, in automated guided vehicles (AGVs), incorporating an ultra-capacitor module allows high-frequency fast-charging cycles (often completed in under 30 seconds), minimizing warehouse downtime. In telecom towers and smart home systems, the combination of smart stacking lithium or sodium-ion packs with localized capacitors safeguards sensitive transmitters from grid switching surges.
Why global Tier-1 integrators and procurement directors partner with Fujian SK Battery Co., Ltd. for custom power projects.
Based in Fujian, the global hub of lithium extraction, cell components, and precursor manufacturing. This proximity ensures lower raw material logistics costs and continuous supply chain resilience.
Our manufacturing processes comply with international norms including UN38.3, CE, UL, and IEC testing parameters, ensuring seamless import customs procedures and localized standard acceptance.
From low-temperature starting options (-40°C sodium-ion auto packs) to space-optimized non-rechargeable thin cells, our design team constructs solutions optimized to your physical footprints.
Global logistics, compliance protocols, and testing benchmarks represent the main bottlenecks for procurement teams securing energy storage products. Fujian SK Battery Co., Ltd. simplifies this workflow. Our location in Fujian provides direct highway access to deepwater container ports, simplifying standard and hazmat (Class 9) shipping compliance. We support our customers through full technical validation phases, offering detailed material safety data sheets (MSDS), cell sorting documentation, and cycle testing logs.
Ultra-capacitors feature incredibly low Equivalent Series Resistance (ESR), meaning they can accept or deliver massive current surges instantly. Standard batteries degrade quickly under high current pulses. Putting them together protects the batteries from high thermal loads, reduces voltage drop during startup, and significantly improves system efficiency at sub-zero temperatures.
Our Sodium-ion starting battery (12V 40ah 640CCA) functions effectively at temperatures down to -40°C. Sodium ions exhibit superior ionic conductivity in ester-based electrolytes at lower temperatures compared to lithium, preventing dendrite formation and ensuring stable starter currents for automotive and marine systems in sub-zero climates.
We deliver products equipped with comprehensive testing portfolios, including UN38.3 certification for transport safety, MSDS documentation, CE directives, and IEC compliance protocols. Our production framework follows standard ISO manufacturing controls to assure quality consistency across high-volume production batches.
