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 widely used lithium iron phosphate cathodes can open cracks and quickly degrade batteries.
