Pseudocapacitors 50F - 300F

Maxwell’s proprietary pseudocapacitor technology is one of the first commercially available hybrid capacitor products on the market. Our pseudocapacitors serve those customers in need of an energy storage solution that provides a combination of higher energy reserve with fast power delivery and fast charging, a long operating lifetime that reduces maintenance efforts, and a compact, lightweight and cylindrical form factor that provides flexibility for a variety of system designs.

How is a Pseudocapacitor Different from an Ultracapacitor?

The pseudocapacitor’s capabilities reside in between the Ultracapacitor and the battery. Using the best of both worlds, the pseudocapacitor is able to provide a quick release of energy via an electrostatic mechanism (like an Ultracapacitor) and higher storage capacity via an electrochemical mechanism (like a battery). Maxwell’s pseudocapacitors have approximately 50 to 100% more energy than Ultracapacitors of similar physical dimensions. Our pseudocapacitor technology is engineered to serve the needs of low-duty cycle applications that require more energy and a fast state of charge.
