"SMBs are the focus of intense research because they theoretically combine the best of both types of batteries."

Another battery tech that is probably like self-driving - promise, unforeseen challenges getting to market, eventually getting there, but delivering somewhat less than the promise.

But I should say that I mean that optimistically - like it's on the self-driving trajectory, not the fusion trajectory.
