About CAP-XX
CAP-XX is a global leader in designing and manufacturing thin, flat supercapacitors and energy management systems for portable and compact electronic devices. Their supercapacitors offer high power and energy density in a space-efficient prismatic package—ideal for power-demanding consumer, industrial, and automotive applications.
CAP-XX develops and markets supercapacitors for use in handheld computers, POS terminals, telemetry units, tracking devices, digital cameras, tablets, mobile phones, energy harvesting systems, and micro-hybrid vehicles.
Key features include high power and energy density, high cell voltage, a wide temperature range, low leakage and charge current, and ultra-thin packaging for space-constrained designs.
These supercapacitors deliver peak power for pulsed loads, reliable backup for mission-critical systems, and battery-free energy storage for clean-tech solutions. They enable manufacturers to add high-power functionality while reducing battery size, weight, cost, component count, and environmental impact.
