New supercapacitor has the potential for “astonishingly high” capacity

Supercapacitors, which can be charged rapidly and deliver intense bursts of power, are a hot topic these days. However, current supercapacitors use components made of carbon, which require high temperatures and harsh chemicals to produce. Now researchers at MIT and elsewhere have developed a supercapacitor that uses no conductive carbon, and that could potentially produce… Read more »

Ultracap manufacturer Skeleton Technologies receives €13 million Series C investment

European ultracapacitor manufacturer Skeleton Technologies has raised €13 million ($14.5 million) in new Series C investment, bringing the company’s total financing to €26.7 million ($30 million). Skeleton plans to use the new funding to accelerate its plans to bring graphene ultracapacitors from high-end sectors to the mass market. “We believe Skeleton Technologies has great potential… Read more »

Maxwell introduces higher-voltage ultracapacitor cell

Maxwell Technologies has introduced a new addition to its K2 family of ultracapacitor cells. A 3-volt, 3,000-farad cell is now available in sample quantities. The new cell offers 31% higher power than Maxwell’s existing 2.7-volt, 3,000-farad cell, and is packaged in the same industry-standard 60 mm cylindrical form factor. Maxwell points out that customers can… Read more »

Skeleton Technologies scores €4 million in new investment for its graphene ultracapacitors

Ultracapacitor manufacturer Skeleton Technologies has secured a €4 million investment from the energy-oriented investment company KIC InnoEnergy, part of €9.8 million in Series B financing raised by Skeleton last year. “We see KIC InnoEnergy as a strong, value-added partner, with a number of their investors being current or potential customers of Skeleton Technologies,” said Skeleton… Read more »

Scrap tires transformed into supercapacitor electrodes

Some of the 300 million tires discarded each year in the US could be recycled and used in electrodes for supercapacitors, using a new technology developed at Oak Ridge National Laboratory and Drexel University. The process is described in a paper published in ChemSusChem, titled “Waste Tire Derived Carbon-Polymer Composite Paper as Pseudocapacitive Electrode with… Read more »

2016 Cadillacs to use Maxwell ultracapacitors in start-stop system

Start-stop vehicles (SSVs, if you will) occupy the bottom rung of the electrification ladder, and they’re growing in importance as global OEMs search for ways to meet tightening emissions standards (anything other than selling EVs, it sometimes seems). Over 40 percent of new cars sold in Europe already incorporate start-stop technology. A battery-based start-stop system… Read more »

SkelStart Engine Start Module uses ultracapacitors to eliminate dead batteries

Skeleton Technologies’ new ultracapacitor-based 24 V Engine Start Module (SkelStart ESM) is designed to ensure trouble-free engine starting in any conditions. Batteries are a major headache in the trucking industry, particularly in cold climates. Long-haul drivers often leave engines idling for long periods to keep batteries charged. Starting failures occur when trucks are not used… Read more »

Skeleton Technologies’ new ultracapacitors target heavy transportation market

Skeleton Technologies has launched a new range of cylindrical ultracapacitors that offer specific power performance of up to 111 kW/kg, specific energy up to 9.6 Wh/kg, and capacitance up to 4500 farads. Skeleton hopes that the high energy density achieved by the SkelCap 4500 series will be a good fit for the heavy transportation market,… Read more »

Skeleton Technologies raises €9.8 million in Series B, aims to make ultracapacitors the future for EVs

Estonian/German ultracapacitor maker Skeleton Technologies has raised Series B financing of €9.8 million ($10.7 million) from a consortium that includes electrical equipment manufacturer Harju Elekter Group and Baltic investment firm UP Invest. The company plans to use the funds to ramp up production of its graphene-based ultracapacitors. Customers include hybrid truck manufacturers, Tier 1 suppliers,… Read more »

Maxwell Technologies introduces 24-volt versions of ultracapacitor-based Engine Start Module

As every truck driver or heavy equipment operator knows, diesel engines can be difficult to start in low temperatures, or after not being started for long periods. Maxwell Technologies’ Engine Start Module (ESM) is an ultracapacitor-based system that takes over the engine cranking function and remains fully charged, even if battery voltage drops. Now Maxwell… Read more »
