Coretec Group Inc (CRTG)

One thing I heard is that there are many silicon anode players, but cycle life is lacking in their efforts. Coretec is loading their test cells with silicon nano particles that are then treated to a polymer coating. (artificial SEI layer) These particles still swell upon lithiation but don’t tend to ‘pulverize’ because they are so tiny, so they don’t lose contact with the conductor. THIS SOUNDS KEY TO CYCLE LIFE. A 500 watt hour/kilogram battery is of little value if it can’t last in real world usage. Amprius uses a totally different technology where they grow silicon nano wires off a metal support. Their business model is such that they intend to manufacture their own complete cells (manufacturing facility in Colorado currently being built out) and I am suspicious this is because their tech doesn't work into existing production lines too well. The Coretec methodology sounds like it has the flexibility to splice into ANYONE’S current battery manufacturing line (they previously have stated such) and that is critical because I also heard the comment that there are billions of dollars invested in current battery production facilities, and the owners of these would obviously resist the need for a re-tool on account of the expense. That's important because GM has stated they will adapt or apply any other technology that is available to improve their battery design. Note also that Coretec has the ability to manufacture films in their own lab and I bet they are doing it on fairly mainstream machinery. Simple and adaptable and when I say 'adaptable' I mean to focus on Coretec's business model which appears to be the sale or licensing of their own proprietary active material to any and all who want to use it so... a wide field of potential customers likely exists.
