Hyundai’s hybrid weapon?

A couple of years ago, when it was speculated that Toyota would use lithium in the third generation Prius, I thought the world of hybrid cars was ready to explode. Unfortunately, Toyota chose the safe and reliable path and stuck with NiMH.

Since then, there has been a lot of talk about lithium chemistry’s, and which one is better. Is it lithium cobalt, phosphorous, magnesium, etc?

At the LA Auto Show, Hyundai said it was lithium polymer.

Today, Technology Review has a pretty interesting piece on Seeo, Inc. and their latest use of “thin films of polymer as the electrolyte and high-energy-density, light-weight electrodes” which result in “safer, longer-lasting, lighter, and cheaper” batteries.

While some critics maintain that polymer electrolytes are not feasible for quick charge hybrids because of low ionic conductivity, the fact that Hyundai seems prepared to bet its hybrid future on related technology is quite interesting.
