• More than two-thirds of the copper will be found in car’s wiring harness and electrical components.
• Copper has the highest conductivity of any metal that can be practically used for conveying electricity.
• Copper is an important natural resource and there’s no danger of running out of it. According to US Geological Survey (USGS), worldwide resources of this valuable metal exceed 3 billion metric tons (more than 6.5 trillion pounds), of which only about 12% has been mined throughout history. Nearly all of this is still in circulation because copper’s recycling rate is higher than that of any engineering metal."
While some GM'ers are predicting a substantial price reduction for the Volt in future years as volumes increase, the Council is not optimistic.
'Battery technology has been developing rapidly, but steep declines in cost do not appear likely over the next couple of decades because lithium-ion batteries are already produced in large quantities for cell phones and laptop computers,' the Council says."
'Work' means running a car, and that's a tough life. Even so, the batteries in electric cars are expected to last about a decade"

"During an information-heavy battery and technology update on the Chevy Volt's progress recently, GM said the following about the 16 kWh battery pack in the plug-in car:
'The biggest challenge in testing is hot-weather storage of the vehicle. Currently, ten years of battery life is the norm, but some people could get more battery life depending on the climate where they live and their driving conditions.
We understand that outside temperatures can have a big impact on how a battery operates and will affect the Volt as well, but the good news for Volt fans is that Green Car Advisor got it wrong. They said that hot weather Volt owners will get less than ten years of life from the pack, saying Volts in 'many parts of the western and southern U.S.' would not get 'the normal 10-year life of the battery.' Not true, says GM, which is confident that everyone will get 10 years from the pack. GM's hybrid and battery technology communication spokesman Brian Corbett told AutoblogGreen that, 'in more moderate areas of the country, battery performance could last beyond 10 years. 10 years is our minimum target life for everybody.'
