Maxwell is a global leader in the development and manufacture of innovative, cost-effective energy storage and power delivery solutions. Our ultracapacitor products provide safe and reliable power solutions for applications in consumer and industrial electronics, transportation, grid and telecommunications.
Maxwell ultracapacitor products store energy in an electrical field that is larger than that of a capacitor – meaning ultracapacitors have greater energy storage capacity than capacitors. This electrostatic energy storage mechanism enables ultracapacitors to charge and discharge in as little as fractions of a second, perform normally over a broad temperature range -40 degrees to +65 degrees C, operate reliably in hundreds of thousands or more duty cycles and resist shock and vibration. Maxwell offers ultracapacitor cells ranging in capacitance from 1F to 3400 farads and multi-cell modules ranging from 16 to 160 volts, which have proven to deliver high power, whether used alone or paired with batteries, in a variety of applications from automotive or industrial to consumer electronics, transportation and beyond.
