Coretec cites positive results from tests on nanowire for batteries

ANN ARBOR–The Coretec Group Inc. (OTCQB: CRTG), developers of silicon anode active materials for lithium-ion batteries and cyclohexasilane (CHS) for cleantech and emerging tech applications, today announced the initial findings from a recent series of CHS tests performed in partnership with The French Alternative Energies and Atomic Energy Commission (CEA).

Earlier this year, Coretec began working with Pascale Chenevier, senior scientist in nanosciences for energy at The CEA in France to test the potential growth of silicon nanowires, a key material in the development of lithium-ion batteries. The goal of the tests was to determine the ability to grow silicon nanowires from Coretec’s proprietary CHS technology.

During initial testing, The CEA found promising results. The organization has previously used several silane-based materials in their research and revealed that CHS demonstrated the lowest deposition temperatures they have observed to date and showed the highest yields of silicon nanomaterials. Additionally, the testing found a unique hybrid of composite materials, consisting of both nanowires as well as nanoflakes, when using CHS as a silicon source.

“The unique low temperature reactivity of CHS is really promising,” Chenevier said. “It opens unexpected new latitude to tune both the nanostructure and chemical composition of our composites for enhanced cycling.”

Added Coretec CEO Ramez Elgammal: “While only a first step, we are pleased with the initial results of our CHS testing with The CEA, positioning us well for continued and more advanced analysis that we hope to demonstrate with potential customers and partners. There is still much more to discover, but these preliminary test results demonstrate a promising future for the use of CHS in developing lithium-ion batteries.”

The Coretec Group and The CEA will embark upon further research to test CHS’ ability to grow nanowires, in addition to further exploring the potential of newly developed nanoflakes.

Coretec is developing a portfolio of engineered silicon to improve energy-focused verticals, including electric vehicle and consumer batteries, LEDs, and semiconductors, as well as 3D volumetric displays and printable electronics. The Coretec Group serves the global technology markets in energy, electronics, semiconductor, solar, health, environment, and security.
