The alloy composition is necessary but it’s the process that allows you to make a product. Developing the process is where you flush the millions $.
I won’t dispute what you say, but I will say that I haven’t seen much in the of patents in the US by Li or Eontec. If it isn’t patented, then everyone can do it. It is always easier for someone to reverse engineer (industrial espionage) the Process than to originally develop it. Without patents, doesn’t it make sense for Foxconn to try to steal the process?
And the process will continue to change to optimize production and minimize the rejects and remelt of scrap. This still remains the ultimate task: to reduce the rejects and scraps. Once this is truly satisfied, adoption will be much faster. And finally, the cycling time has not yet been optimized. This is an extreme cost and productivity factor that must be overcome as well.
