Not so fast: Some batteries can be pushed too far

Scientists find overabundance of intentional defects can cause battery cathodes to fail

16-Jan-2020

Intentional defects in batteries have given Rice University scientists a window into the hazards of pushing lithium-ion cells too far. New simulations by Rice materials scientist Ming Tang and graduate student Kaiqi Yang, detailed in the Journal of Materials Chemistry A, shows too much stress in ...

Go with the flow: Scientists design new grid batteries for renewable energy

12-Nov-2019

How do you store renewable energy so it's there when you need it, even when the sun isn't shining or the wind isn't blowing? Giant batteries designed for the electrical grid - called flow batteries, which store electricity in tanks of liquid electrolyte - could be the answer, but so far utilities ...
