What did I do to get you so worked up, Ted? To the point that everything I say has to be refuted, denied, argued with?
Li-Po simply does NOT refer to a specific chemistry, whatever you and the RC crowd may think, or how you may use the term. Strictly speaking, it refers to a Li-ion battery which has a polymerized, or "gelled" electrolyte. That meaning has been expanded somewhat to refer to pretty much all pouch-type cells. But it has nothing to do with the chemistry.
I HAVE read through pretty much all of the "Battery U" website, and I haven't seen a single place where they refute what I've said. Where, exactly, do you see them saying something different? I'm happy to admit when I'm proven wrong...you just haven't shown me anything that proves me wrong yet. Even your favorite reference, Battery U, just doesn't back up what you're saying. You won't find a single authoritative reference that equates Li-Po with a particular chemistry.
Actually, yes, I DO know more than you. Not just because I'm an EE who actually works in the field, and has spent years studying the subject, but also because I keep an open mind and don't cling to my wrong perceptions regardless of the facts. I don't pretend to speak for every EV forum online, or every single person in the community, but facts are facts.
