How Can the Performance of Batteries in Electric Cars be Improved?

Wednesday, December 19th, 2012

I have been driving a Chevy VOLT for a year and a half. I have more than 26,000 miles on it, and have used 100 gallons of gasoline. That works out to more than 250 mpg. Of course, I have been charging the VOLT at home every night, and at the office during the day but my electric bills at both places are not noticeably higher.
