While consumers may simply crave longer-lasting batteries for electronic gadgets, the holy grail for many material scientists is batteries that can pump power into the grid for hours.
Stanford University researchers today detailed a new electrode material they claim holds promise for grid storage batteries that can work 30 years without a dramatic decline in performance.
In the lab, the copper and iron-based nano-engineered material was able to take 40,000 charge/discharge cycles while still maintaining an 80 percent capacity. By contrast, the lithium ion batteries used in consumer electronics degrade noticeably after only a few hundred cycles.
The … Read more
