Cellergy Ltd. is a specialized manufacturer of high-performance, ultra-thin printed supercapacitors, founded in 2000 and headquartered in Migdal HaEmek, Israel. The company focuses on energy storage solutions for backup power, peak-power assist, and energy harvesting applications across industrial, automotive, medical, and IoT sectors. Its core product lines include the CLG and CLC series of low-profile prismatic supercapacitors, offered in both bare cell and PCB-mountable configurations with voltages from 2.3V to 5.5V and capacitance values up to several Farads. Cellergy is recognized for its patented thick-film screen-printing technology that enables cost-effective mass production of environmentally friendly, RoHS-compliant cells with extremely low equivalent series resistance (ESR) and high power density. The company’s components are widely used in solid-state drives, smart meters, automotive telematics, GPS modules, and real-time clock backup circuits. Unlike traditional cylindrical supercapacitors, Cellergy’s rectangular packaging allows for easier SMT assembly, space-saving designs, and high reliability in harsh environments. Cellergy holds a niche but growing market position in the printed supercapacitor segment, competing with players like CAP-XX and Eaton. Its technical advantages include rapid charge/discharge capability, long cycle life exceeding 500,000 cycles, and operational temperature ranges from -40°C to +85°C. Through continuous innovation in electrode and electrolyte materials, the company serves an expanding global customer base demanding miniaturized, maintenance-free energy storage.
