New machine learning method accurately predicts battery state of health

Green Car Congress

We first understand battery degradation through collaborations with the CALCE group at the University of Maryland, where in-house degradation testing of batteries was carried out. By contrast, our work is built from the ground up. 2021) “Machine learning pipeline for battery state-of-health estimation.”

U Maryland team devises new method to stabilize high-capacity Si anodes for Li-ion batteries: interfacial oxygen

Green Car Congress

Researchers at the University of Maryland have improved the cycle life of silicon/carbon matrix-composite electrodes by 300%, even at mass loadings, solely by the chemical tailoring of the interface between the silicon and the carbon with atomic oxygen.

Study finds GHG methane offsets its warming ~30% and precipitation increase ~60% by short-wave absorption

Green Car Congress

A new study by researchers from the University of California, Riverside and colleagues in the US and Europe has now found that methane short-wave absorption counteracts ~30% of the surface warming associated with its long-wave radiative effects.
