Internal Currents in Lithium Batteries after Fast Charging

In lithium batteries after fast charging, researchers measured the persistence of internal currents and found that large local currents continue even after charging has stopped. The work uses hard x-ray 3D imaging in a novel way and sheds light on the causes of thermal runaway and the catastrophic failure of lithium batteries at rest. Read more »PPT-icon-35 PDF-icon-35

Improving Carbon Retention in Grassland Soil from Point Reyes

Soil organic carbon directly influences the life-supporting services provided by soils, including the production of food and the regulation of atmospheric carbon dioxide. To better understand how minerals such as calcium affect carbon accumulation in soil, researchers studied soils collected from Point Reyes National Seashore. Read more »
