Maxwell Technologies introduces 3V, 3,000-farad ultracapacitor; 31% higher power than 2.7V cell

17 February 2016

Maxwell Technologies, Inc. has introduced the newest addition to its K2 family—a 3-volt (3V), 3,000-farad ultracapacitor cell, now available in sample quantities. With 31% higher power than Maxwell’s leading 2.7-volt, 3,000-farad cell in the industry-standard 60 mm cylindrical form factor, customers now have the flexibility to either increase available power and energy in the same volume or significantly cost-optimize their system designs with fewer cells or modules while maintaining the same power and energy.

The new 3V cell design also incorporates Maxwell’s proprietary DuraBlue Advanced Shock and Vibration Technology (earlier post) to provide three times the vibrational resistance and four times the shock immunity of previous ultracapacitor-based competitive offerings, which will maximize life in demanding transportation environments such as onboard rail, hybrid bus and other applications.

With the 3V cell, the transportation industry has a new way to retrofit systems to increase power, reduce engine weight and improve fuel efficiency.

Additionally, grid markets will enjoy options for more available power to smooth power intermittencies and reduce costs, resulting in increased return on grid energy storage investments. Existing K2 2.7 and 2.85-volt customers can also seamlessly upgrade systems using the industry-standard 60 mm cylindrical cell format while maintaining the same life performance criteria as our 2.7-volt cells.

The growing need for increased power density in many applications such as transportation, wind and grid has resulted in Maxwell adding a 3V ultracapacitor to their large cell offerings. Either used alone or in hybrid configurations with batteries, this new 3V large cell will help to reduce the overall cost and weight of the system and support in attaining operational efficiencies. This product is going to be a game changer for the ultracapacitor industry.

Maxwell ultracapacitors perform reliably over a large temperature range, between minus 40 degrees to 65 degrees Celsius. The devices’ longevity means customers experience dependable operation for hundreds of thousands of duty cycles without the performance snags caused by shock and vibration.

Maxwell cells range in capacitance from 1 to 3,400 farads and multi-cell modules range from 16 to 160 volts.

Bah, they don't say if the power levels are average in use or peak.  They'll probably vary by 50% between peak and minimum voltage.  They should have given a figure for current.

There's no datasheet anywhere in the Maxwell site links on this product.  You can go around and around in circles on applications and modules and such, but no datasheet on the cell itself.

My company is just starting to use the 160 V Maxwell multi-cell modules to recover regen power from the servo drives instead of wasting it as heat with a resistor bank. Maybe we should put a green leaf symbol on our machine.

I still can't find any data sheets. So as far as I'm concerned this is just a marketing claim until they produce actual data to analyze.
