Replying to: blace (Jun 02, 2008 4:03 pm) I would expect closer to $50 thou or a big lease on the batteries. Have you read the above article. There are still challenges to making the car safe to park in you garage.   the biggest challenge is to manage the thermal dynamics of the batteries so that the batteries are the same temperature.   Welcome to the Forum

Replying to: blace (Jun 02, 2008 4:03 pm) I hope GM can get it together fast enough to make a difference.   This things take a little bit of time. Like the article stated they do have challenges (gagrice) but those challenges can be over come. GM can always accelerate their plans to introduce the vehicle into the market but that will take extra money and manpower in which GM cannot afford. "Uncle sam help me please."   Can't we start a new revolution away from the 900 Hp, 0-60 in 5 sec., 1/4 mile in ?? ?? , blow your doors off, drunken, gas station to gas station stupidity???   If gas and oil keep going up then I believe there will be a dramatic philosophical change to the auto consumer. Where MPG will be more of a priority than HP when purchasing a car. It's started to happen. Come to think about it, I still pick up "Road and Track" and "Motor Trend" and these magazines are so behind in the times that they still write about these power hog of a vehicles.

Replying to: pf_flyer (Jan 22, 2008 5:52 am) There are newer technology lithium ion batteries using nano-particle suspensions, composite cathode materials, and various physical and chemical modifications that overcome all of these limitations.        Various manufacturers have invented various alternative configurations, all of which have greatly increased cycle life, charge and discharge rate, and safety. Thermal run-away, copper plating, lithium plating at low temperature, and exposed graphite-oxygen-electrolyte issues have all been resolved in these newer designs.         Production is already ramping up with some of these new technologies but there are many more in the pipeline, so I expect within a few years, the lithium batteries won't resemble what we see today at all, however, even now there are companies producing lithium batteries with much longer cycle life, operating parameters, and without the thermal-runaway or fire hazards of older technologies.

From laptops to cars, advanced batteries have become a major factor in innovation. And if Panasonic Corp.'s possible takeover of Sanyo Electric Co. goes through, the merged company could become a dominant force in the fast-growing business.   http://online.wsj.com/article/SB122589242452601431.html?mod=googlenews_wsj
