Less may be more in next-gen batteries

24-Jan-2020

The process of developing better rechargeable batteries may be cloudy, but there's an alumina lining. A slim layer of the metal oxide applied to common cathodes by engineers at Rice University's Brown School of Engineering revealed new phenomena that could lead to batteries that are better geared ...

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 ...
