Solid-state battery with salt instead of lithium - Joint venture with Fraunhofer IKTS to help achieve breakthrough - Interview

In an interview with, Altech Advanced Materials AG CEO Uwe Ahrens goes into detail and explains the current state of research and development. The fully developed sodium-alumina solid-state battery is to be launched under the name CERENERGY®. According to board member Uwe Ahrens, a possible plant could be in production in 2025 or 2026 once planning is complete (DFS).

Board member Uwe Ahrens told

  • "Silumina Anode® is a ceramic-coated graphite/silicon anode composite material that is expected to improve the performance of lithium-ion batteries significantly. We intend to produce this in Schwarze Pumpe, Saxony. The pilot plant is already under construction."
  • "We have been testing micro half cells successfully for over a year and can prove that this battery with our material shows stable results over 500 charge cycles.”
  • "In addition to Silumina Anode®, we now want to work with Fraunhofer IKTS to launch CERENERGY® battery technology, which has already been developed."
  • "This battery is non-flammable and does not use any critical raw materials, such as lithium, cobalt or graphite, which are used in the lithium-ion battery. In CERENERGY® batteries, high-purity aluminum oxide is used for the ceramic solid electrolyte, and the cathode medium used is only common salt, not lithium."
  • "CERENERGY® batteries are ideal for use as grid storage and are produced exclusively for this market and not for electromobility."
  • "We want to create a production capacity of 100 MWh per year (line 1) at our Schwarze Pumpe site as a first step, and then scale up production quickly."

    dynaCERT CEO Jim Payne on attractive hydrogen opportunities

    Toronto/Hannover (ots) - dynaCERT is a Canadian company and has developed a hydrogen technology for diesel engines, that also provides significant fuel savings to the operator. The so-called HydraGEN™ technology uses a proprietary and patented electrolysis system to turn distilled water into H2 & O2 gases that are produced on demand. The company focuses on reducing the amount of Greenhouse gases (GHG) emitted by the ...
