Skeleton and Sumitomo partner to distribute graphene-based ultracapacitors

Ultracapacitor manufacturer Skeleton Technologies has signed a distribution agreement with Sumitomo Europe to provide energy storage solutions for the EV industry. Skeleton’s graphene-based ultracapacitors boast high power density, a recharge time of 2-3 seconds and more than one million life cycles. In EVs, ultracapacitors can be used in tandem with lithium-ion batteries, an arrangement that… Read more »

Maxwell Technologies localizes ultracapacitor production for Chinese e-buses

Energy storage solution provider Maxwell Technologies (NASDAQ: MXWL) has announced an agreement with CRRC Qingdao Sifang Rolling Stock Research Institute (CRRC-SRI) to localize manufacturing of its ultracapacitor-based modules for use in the China new energy bus market. Local production is expected to begin in China in the second half of 2017, coinciding with the peak… Read more »

Could a new supercapacitor technology replace batteries?

Supercapacitors, which feature long cycle life and high power density, are a common topic here at Charged – many foresee them working together with batteries. However, researchers from Augmented Optics in collaboration with the University of Surrey and the University of Bristol, have developed new electrolytes that they believe could be used to create supercapacitors… Read more »

Maxwell Technologies unveils 51-volt ultracapacitor module for hybrid buses

Ultracapacitor specialist Maxwell Technologies has introduced a 51-volt module that’s specially designed for use in hybrid buses and other high-duty cycle applications. The latest addition to Maxwell’s lineup features a 2.85 V, 3,400-farad ultracapacitor cell that delivers the company’s highest available energy and power density. Maxwell’s 51 V module includes an active cooling system, which… Read more »

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 »
