ION Storage Systems to partner with U Maryland on $4.8M ARPA-E EVs4ALL award

Green Car Congress

million grant awarded to the University of Maryland (UMD). The EVs4ALL project will accelerate this objective by enabling a 5–15-minute charge to 80% of cell capacity. This design will increase the charge and discharge-rate capability, energy density and operative temperature of solid-state lithium batteries.

New machine learning method accurately predicts battery state of health

Green Car Congress

Using segments of charge voltage and current curves, the pipeline engineers 30 features, performs automatic feature selection and calibrates the algorithms. When deployed on cells operated under the fast-charging protocol, the best model achieves a root-mean-squared error of 0.45%. By contrast, our work is built from the ground up.

Sandia testing method yields pathway to better, longer-lasting solid-state batteries

Green Car Congress

To validate the data by measuring where the lithium ions were at different states during charging, the team worked with researchers at the National Institute of Standards and Technology Center for Neutron Research using a technique called neutron depth profiling that can measure where lithium ions are at a particular moment.
