I've never heard of this "impossible triangle" and I'm guessing it's because it's just marketing fluff.

High power, fast charge, and long range are not opposing characteristics. High power and fast charge are probably the same spec, in fact. Charge rates and discharge rates are essentially the same thing as far as battery chemistry is concerned.

Long range is also not something that opposes the other two. Just have a big battery. Big battery = long range = discharge/charge is spread out among more cells.

The real "impossible triangle" is capacity, weight, and cost.
