The UCK Series pushes energy density to 100 Wh/kg — roughly 18x higher than classic carbon EDLCs. These are hybrid lithium-ion capacitor (LIC) cells that combine the fast-charge capability of a supercapacitor with energy storage approaching lithium-ion battery levels.
The UCK Series pushes energy density to 100 Wh/kg — roughly 18x higher than classic carbon EDLCs. These are hybrid lithium-ion capacitor (LIC) cells that combine the fast-charge capability of a supercapacitor with energy storage approaching lithium-ion battery levels. They operate in a 2.8V to 4.0V window and are certified by CE, UL, and RoHS.
Five models cover a range from 6800F to 28000F rated capacitance, making the UCK series suitable for applications ranging from compact AGV packs and drone emergency power to large-scale renewable energy storage buffers. All models support CMS (Capacitor Management System) integration through their predictable linear charge-discharge profiles.
The UCK42V6800C utilizes hybrid lithium-ion capacitor (LIC) technology, combining the electrostatic energy storage mechanism of a supercapacitor with the higher energy storage capability of lithium-ion materials. During charging, lithium ions are stored within the anode structure while charge separation occurs across the capacitor electrode surfaces. This hybrid architecture enables significantly higher energy density than traditional EDLC supercapacitors while preserving rapid charging, high power delivery, and long operational life.
Operating within a 2.8V to 4.0V voltage range, the cell can efficiently absorb and release energy during frequent charge-discharge events. The combination of high energy density and high power capability makes the UCK42V6800C suitable for applications requiring both sustained energy storage and rapid power response, such as electric mobility, renewable energy buffering, and industrial automation systems.
Designed for applications where energy density, compact size, and lightweight construction are critical.
