$this->bbcode_second_pass_quote('Keith_McClary', 'H')as anyone seen a website keeping track of the progress of all these battery technologies?
If you are looking for a brief overview of progress made on battery technology that has already been comercialized, this might help:
$this->bbcode_second_pass_quote('', 'T')o understand what's going on, consider where battery makers have been, where they are now, and the challenges they face.
Michael Sinkula of Envia Systems, an advanced battery startup in California, crunched the numbers and found the energy stored in a battery in 1995 didn't double until more than a decade later, in 2007. Since then, a battery's energy hasn't even risen by 30 percent. And Envia believes most batteries likely won't have doubled again even by 2021.
Until now, major battery advances came from using new materials. Consumer electronics batteries began lasting longer when they switched from relying on nickel, a type of metal, to lithium. research now is focused mainly on improving lithium batteries. "The periodic table is limited," he says, and advancements are becoming increasingly tough.
Given all the money at stake, many researchers are working to improve batteries. Even so, few breakthroughs have materialized. Plus, almost all major research has shifted to cars and power grids.
