Nesscap Energy introduces 3V, 3400-farad ultracapacitor

Nesscap Energy Inc. has introduced its new N60 3V 3400-farad ultracapacitor cell. The new N60 delivers 40% more energy and 42% greater power density compared with Nesscap’s 2.7-volt 3000-farad cell, all within the industry-standard 60mm cylindrical form factor.

The cell’s rugged mechanical design provides vibration and shock performance in compliance with ISO 16750-3 Tables 12 & 14, SAE J2464 and IEC 60068-2-27.

The product offers a number of benefits to system integrators including the ability to scale up system voltages to attain more power and energy within the size and weight specifications of their existing designs. Systems can also be designed with fewer cells resulting in smaller size, reduced weight and lower cost.

N60 may be used as a standalone solution or integrated with battery technology to achieve optimal power, energy, and cost parameters, depending on the needs of the application.



Roll on stop-start systems and mild hybrids.
(or am I missing something.)


Yes, used or in battery EV to avoid unnecessary fast charge of battery for every break operation.


The Nesscap site is irritating.  The press release has no link to data, the site points only to suppliers rather than actual product info, and the series datasheet linked by Digikey does not have the 3V 3400 F units listed yet.

We can get useful info from that, though.  The 2.7 V units achieve 5.2 Wh/kg energy density in the 3500 F size.  40% more is 7.3 Wh/kg.  A 1500 kg vehicle moving at 70 MPH has about 200 Wh of kinetic energy, so a fully-hybridized vehicle able to brake from highway speed to zero with complete energy recovery would need a bit under 30 kg of those things.  They appear to have more than enough power density to do the job for anything but panic-braking situations.


Can these caps achieve a price point below $100/ kWh
or pairing with high density storage could make the average family car at $30k price point. That pays for itself in fuel cost savings.
The dynamic feel of ICE will be the hardest thing synthesize.


You've got references to the part number and a dealer, why don't you calculate the $/kWh yourself?
