Did I miss that or are you saying it rhetorically? I didn’t pull the actual scientific article but this one mentioned decent performance over 800 cycles and 100 mAh/g. I’m not really up on this kind of tech but that seems pretty nifty for a new chemistry .
If you were just being rhetorical I get the frustration. There’s always gremlins hiding somewhere.
Still, I take stuff like this as indicitive that were absolutely not going to be stuck with Li ion forever.
