NEW YORK, March 31, 2010 – For decades, the automobile battery was an essentially static technology, but it’s no longer being taken for granted. Battery technology is now in a starring role in the development of a new generation of electrified vehicles.

But today’s batteries are a far cry from the humble lead-acid battery used for a century in the automobile. The 12-volt lead-acid battery used in traditional automotive applications is rapidly giving way to sophisticated, higher energy and power batteries as the automobile industry shifts further toward electrification.

The advent of hybrid electric vehicles spawned a new generation of batteries, making nickel metal hydride (Ni-MH) batteries the energy storage technology of choice. The nickel used in these batteries is lighter than lead, helping the battery deliver twice the power output for the weight as lead-acid batteries, but the cost of Ni-MH batteries is high – four times that of lead acid. Automakers already believe they have tapped most of the potential of Ni-MH technology and are moving rapidly toward Lithium-ion technology.

Lithium-ion batteries are commonplace in the world of consumer electronics. They’re lighter and more energy dense than other types of batteries, making them ideal for laptop computers, mobile phones and other portable devices.

That makes lithium-ion technology even better for use in cars of the future, right?
