Detours may Make Batteries Better

An illustration shows a battery's cathode undergoing phase transition from iron phosphate (FP) to lithium iron phosphate (LFP) during charging. Simulations by Rice University scientists showed that adding defects -- distortions in their crystal lattices -- could help batteries charge faster.

Here's a case where detours speed up traffic. The result may be better batteries for transportation, electronics and solar energy storage. Scientists at Rice University's Brown School of Engineering have discovered that placing specific defects in the crystalline lattice of lithium iron phosphate-based

Recharging the Batteries
It has been a mixed year so far, with plenty of innovation on display, but a flat economy put a bit of a spoiler on the industry. The forecast for next year is pretty mixed too, with some people predicting a global recession. As the old saying goes, economists have predicted eight of the last three recessions,
