Re: Because they don't know how to make better

There are problems with each of the technologies you mention, mostly cycle life due to different failure mechanisms (i.e. dendrite growth).

Believe me, if someone has something better, it'll get to market in short order.

Also, your numbers are wrong. Lithium metal might give a factor of two, or a factor of five when combined with sulfur. A factor of ten would require combining those with inorganic or solid state electrolytes.

Fascinating. Dendrites blamed when all it would take to prevent them being a problem would be an electron-permeable barrier between the cathode and anode of the battery. They must have SOME material that would work.

Billions of dollars are being spent on this and related problems. Many solutions have been proposed and some have been lab tested. None  are in the market yet.
