lithium ion

The Jeep Renegade combines a lithium-ion battery pack with a small-displacement BLUETEC diesel engine, which together help it achieve a fuel economy of more than 110 miles per gallon.

AFS Trinity Power has developed two fully operational XH-150 SUV prototypes using off-the-shelf components that make it possible for plug-in hybrid electric vehicles to achieve 150 MPG, go 40 miles in all-electric mode, and use gasoline for additional unlimited miles in hybrid mode. The low-cost lithium batteries -- protected from excessive resistive heating by the ultracapacitors -- will make the XH-150 much less expensive to purchase.

Dubbed as the next generation electric car, the all new Chevrolet Volt was the talk of this year"s Detroit Auto Show. Capable of running 40 miles on its initial charge, the Volt re-charges itself as it moves down the road, saving consumers time and money.
