A 3D model by Rice University materials scientists shows the phase evolution of a delithiating lithium iron phosphate cathode undergoing rapid discharge. The "fingerlike" shape adds stress to the system that researchers suspect can lead to cracks in the cathode that degrade the battery. (Credit: Mesoscale Materials Science Group/Rice University)

Not so fast: Some batteries can be pushed too far

Fast charge and discharge of some lithium-ion batteries with intentional defects degrades their performance and endurance, according to Rice University engineers.

Gasification goes green

Rice University engineers have created a light-powered nanoparticle that could shrink the carbon footprint of syngas producers.

Carbon Hub is a climate change research initiative led by Rice University

Rice University launches bold climate change initiative with Shell

With initial support from Shell, Rice University has launched Carbon Hub, a climate change research initiative to fundamentally change how the world uses hydrocarbons. Carbon Hub's goal is a zero-emissions future in which hydrocarbons are not burned. Instead, they are split to make clean hydrogen energy and valuable carbon materials.
