Hyundai LPI hybrid ready to hit Korean market
Will lithium polymer batteries be cost-effective?In just a couple of weeks Hyundai will begin selling the Elantra LPI hybrid in Korea. With a gasoline equivalent of 51 mpg, the Elantra hybrid is out to prove that mild hybrid cars can compete. Of course, it isn't just hybrid technology that makes this vehicle efficient, it's the liquefied petroleum injected engine as well.
Still, Hyundai's recent claim for hybrid fame has revolved around it's lithium polymer battery technology using LG Chem cells. Hyundai claims the battery offers "65% more power density; 15% more energy density; 12% more energy efficiency; and 43% better state-of-charge estimation," according to GreenCarCongress.
In a little more than a year, Hyundai will begin selling it's first hybrid vehicles in the US. We'll find out then how cost-effective is Hyundai's lithium-powered hybrid drive.

So... What's the difference between liquid petroleum and gasoline?
Hyundai sure has come a long way since the 1990s!
I hear conflicting things about Hyundai - whether at end of 09 it will offer a hybrid elantra here or a optima or sonata type vehicle...
why are they SO quiet all the time, no one ever hears a tweet about their strategy for US market
I don't see this mild hybrid with 15-20hp electric motor would greatly improve fuel economy.
anon-
the blue drive Hyundai Sonata is scheduled to hit the US in the later half of 2010. Hyundai has publicly commented on that.
Indigo-
I don't really know much about liquefied petroleum other than it is supposed to burn more efficiently.
Dennis -
I hear you, but I know that GM is predicting a 15 -20 percent improvement in its fuel economy of the next gen. lithium BAS system. Still, the big increase in fuel economy of this vehicle has to be about much more than the hybrid drive.

Does anyone know what the difference is between a lithium ion battery and a lithium polymer battery?
Also (grossly off-topic) can you augment an EV Scooter's 48v PbA battery pack with additional NiMH cells for range extention?
"Lithium polymer technology uses a completely different approach. Rather than using a liquid electrolyte, which requires a robust metal casing, lithium polymer batteries use a polymer gel as the electrolyte, which allows the use of a thinner and lighter aluminum-walled encasement, or pouch. Inside each lithium polymer cell the cathode, separator, and anode are laminated together, enabling much simpler and more reliable manufacturing. This allows the battery pack to be about 20 percent smaller than a lithium-ion battery pack, making it much easier to change the cell footprint to fit the nooks and crannies of available vehicle space."
