Successful showing of the game changing Carbon based Power Capacitors at the Battery Show 7-9 May 2019 in Stuttgart.

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.

A small demonstration of power

Last week we completed some new stress tests on the power capacitor cells at the test facilities of Flanders Make. Here's one of the early results while we prepare the full report. An 18650 cell (2,7V / 1.3 Ah) is fully charged at 10C (13 A at 2,75V) and then...

White Paper 2: Game Changing Carbon based Power Capacitors at Work

Carbon based Power Capacitors are a game changer. These devices deliver energy densities comparable with the best batteries, but with power densities that are only found with supercapacitors. Being supercapacitors, they keep relatively cool and hence share the...

Successful showing of the game changing Carbon based Power Capacitors at the Battery Show

While the exhibition was still dominated by Lithium based battery technology, our visitors were delighted to discover a truely safe and more powerful alternative based on powercapacitors, using advanced carbon nano-materials and aluminium. A major step forward for the...
