How Argonne National Lab Will Make Electric Cars Cheaper

Posted by samzenpus on Wednesday August 20, 2014 @02:09PM from the cheap-charge dept.

ashshy writes Argonne National Lab is leading the charge on next-generation battery research. In an interview with The Motley Fool, Argonne spokesman Jeff Chamberlain explains how new lithium ion chemistries will drive down the cost of electric cars over the next few years. "The advent of lithium ion has truly enabled transportation uses," Chamberlain said. "Because if you remember your freshman chemistry, you think of the periodic table -- lithium is in the upper left-hand corner of the periodic table. Only hydrogen and helium are lighter on an atomic basis."

The weight of lithium is pretty irrelevant. There are no currently existing battery technologies where Li is more than 10% of the total weight of the battery, and standard battery types are significantly below that. If the active ion weight were the prime factor, there would be more interest in beryllium batteries (just 30% more weight vs. twice the charge per ion).
