Lithium ion polymer is used in some (hyundai) vehicle batteries already, they say they're 20% more economical - space wise - and they include a lifetime warranty on the battery. Citing the polymer being a gel base versus electrolyte base. Better thermal properties and cycle rates too.
I work for Hyundai. Not too savvy on the techie stuff beyond that, but I wonder if that's a similar (but obviously extrapolated) technology being referenced?
