Kurt.Energy specialises in trustworthy clean energy system solutions.   Core building blocks are carbon based power capacitors, we call them our Blue Cell Power Capacitors. Contrary to classical lithium based batteries, these are simple to use, work from -40°C to +80°C, have lifecycles (full charge/descharge) from 10000 to 50000 cycles, no BMS needed, no thermal risk. The most cost-efficient and long-life solution on the market.

Very low temperature tests by T.U.Munich

The Technical University of Munich, Institute of Astronautics is conducting a test campaign at very low temperatures. The first results are very promising. The following graph shows a capacity test of a 18650 cell from 0 °C up to -50 °C. The graph clearly shows that...

Visit us at the Battery Show 2020 Stuttgart

Altreonic - had a very successful participation at Battery Show 2019 in Stuttgart. Our visitors were delighted to discover a truely safe and more powerful alternative based on powercapacitors, using advanced carbon nano-materials. A major step forward for...

TECHtalk Battle of the batteries 26 Nov 2019 has been presenting our carbon based hybrid power capacitors in comparison with other battery technologies. Details and registration for this event. See Hereby the presentation: 20191220 Altreonic BattleofBatteriesHD

Unmatched robustness of blue cell power capacitors

How robust are blue cell power capacitors? You only know this when you test them beyond the specifications of the datasheet. While the full test report is being prepared, hereby a few early test results.  The main stress and abuse tests are as follows: Charging and...
