02-01-02 BD70-9 Ness Capacitor Co. introduces 2.7 Volt ultracapacitors. The company says it is the first ultracapacitor family with continuous operating Voltage rating higher than 2.5 Volts. The NESS 2.7 V ultracapacitor is said to have the highest capacitance and energy storage densities and the lowest Equivalent Series Resistance of any commercially available components of comparable size and weight. The key to performance is attributed to its porous carbon electrodes. Some targeted markets are for EVs and hybrid EVs acceleration and braking, industrial actuation and control, wind and fuel cell power conversion, and UPS switchover bridging.
