In his career focused on energy storage science, Jianlin Li has learned that discovering new ways to process and assemble batteries is just as important as the development of new materials.

Data from the ORNL Free Air CO2 Enrichment experiment were combined with observations from more than 100 other FACE sites for this analysis, which revealed new insights about the relationship between plant biomass growth and soil carbon storage. Credit: Jeff Warren/ORNL, U.S. Dept. of Energy

Oak Ridge National Laboratory was among an international team, led by Lawrence Livermore National Laboratory, who synthesized 108 elevated carbon dioxide, or CO2, experiments performed in various ecosystems to find out how much carbon is

Urban climate modeling

Researchers at Oak Ridge National Laboratory have identified a statistical relationship between the growth of cities and the spread of paved surfaces like roads and sidewalks. These impervious surfaces impede the flow of water into the ground, affecting the water cycle and, by extension, the climate.
