Is it well-enough-known in the field
It should be at a theoretical level. But LiON batteries are relatively new beasts. So engineers used to dealing with SLA and NiCad and their relatively large plate spacings (and low shunt capacitance) might be dropping this phenomenon out of their analysis. Battery plate configurations look nothing like battery cells of yore.
Its back to first principles, where things like electrical resistance have to consider charge mobility and density rather than just Ohms.
