Skeptics repeatedly ask a legitimate question: What happens to all the battery packs? Do they just end up in landfills?http://www.greencarreports.com/news/1093810_e...
We broke down exactly what might happen to all these battery packs in the article above on Green Car Reports.
A quick rundown? While some could be recycled, the stuff inside lithium-ion battery packs is relatively inexpensive, and technological breakthroughs will change things drastically in the coming years.
A secondary-use will be the most likely outcome for many of these massive battery packs. Maybe bundling a used electric-car battery with a solar panel system on a house to both create and store renewable energy for peak utility times.
