Ioxus unveils 16V/58F iMOD ultracapacitor module series for alternative energy markets

Ioxus, Inc., a manufacturer of ultracapacitor technology for transportation, alternative energy, medical, industrial and consumer product markets (earlier post), unveiled its first 16V/58F iMOD series of ultracapacitor modules. The 16V/58F iMOD series cuts development time by delivering a ready-to-use package at what Ioxus says is the lowest cost in the industry.

With the increase in adaptation of hybrid drives and clean technologies, there is a high demand for more rugged, compact and lower-price ultracapacitor modules with improved cell balancing. Ioxus is targeting its 16V/58F iMOD modules initially for wind turbine pitch control, said Chad Hall, VP of Sales, with starting systems for large vehicles and off-road equipment next, automotive subsystems, backup power/UPS/ride through and power conditioning for renewable energy systems.

Hall also said the micro-hybrid applications could become a solid market for the ultracapacitor modules, as “ultracapacitors are the only technology that can handle the rigorous cycle demands.”

Key features and benefits of the 16V/58 iMOD modules—which, Hall noted, are sized to match the footprints of common 12V lead-acid batteries—include:

  • A 16V working voltage sized to parallel with or replace common battery sizes.
  • Individually balanced cells that eliminate the need to custom design management and packaging strategies for the largest markets.
  • Threaded, protected terminals that are easy to install, monitor and maintain.
  • Strong environmental protection for commercial and industrial applications.
  • Short module walls with short screws required for mounting, easy installation and removal of screws, and improved thermal performance.
  • Low ESR with better constant current, higher power density and higher efficiency then market competition.
  • Rugged design for six solder points near cell circumference for stability and an extra thick circuit board for rigidity.
  • Molded-in part number that is not easily removed.
  • Standard architecture that fits within the footprint of other modules on the market.

This is a complete, ready to install package. You can go up to 750V without any external management, you can run it in parallel to a 12V battery or replace a 12V battery. It’s ruggedized to handle industrial environments.

Ioxus has performed the necessary compliance standards required with all UL94-V0 materials used for the 16V/58F iMOD modules to be used in stationary and mobile applications. These tests include RoHS, UL810a pending, Vibration IEC60068-2-6, Shock IEC60068-2-27, -29 and Random Drop MIL-STD-202G METHOD 203C.

Ioxus offers the highest power and energy density ultracapacitors and hybrid capacitors ranging in size from 100 Farads to 5,000 Farads. Ioxus ultracapacitors have two to three times higher power compared to other ultracapacitors, with smaller, lighter weight modules and systems. Its family of ultracapacitors is uniquely optimized for high performance with low resistance, ideal for delivering high power bursts for acceleration, energy recapture, peak load shaving and high power applications. Ioxus is headquartered in Oneonta, NY.



Sooner or latter, somebody will learn how to combine super-caps with high energy density batteries, for a more effective e-storage pack.


Anyone got any idea of what the energy density of this is?


How many watthours per kilogram for these puppies? How many watthours per dollar?


A previous post mentions W/kg, Wh/kg and $/unit figures for early production units (nearly 2 years ago).


Cheers. At 4-5Whkg I don't think we should throw out our lithium batteries just yet! :-)


Thanks EP,

Actually, Maxwell Boostcaps seem to be around 3 Wh/kg, so this is actually much better. If you had 70 Kg of Ioxus caps,you could store about 350 watt hours (1 mile worth) of charge. The cost is probably still prohibitive, but you could make a series hybrid with a genset that runs about half the time at its optimum efficiency and produces about 2x the energy the car needs to maintain 65 mph. It's a sawtooth charge and discharge pattern. The cool part is, with supercaps you can recharge half of every minute, for 150,000 miles and never wear out the supercaps. If your genset runs at 37% efficiency (50% if you could get a free piston generator going) you're going to get almost double the average efficiency of an ICE engine on a normal drive cycle, plus stop-start and regenerative braking.



How about spending 1 minute to visit their website and download the spec sheet?


Since the spec sheet claims 2.8 Wh/kg, I'd say HB was darn close.
