UPTON, NY A team of researchers led by chemists at the U.S. Department of Energy s (DOE) Brookhaven National Laboratory has studied an elusive property in cathode materials, called a valence gradient, to understand its effect on battery performance. The findings, published in
Nature Communications, demonstrated that the valence gradient can serve as a new approach for stabilizing the structure of high-nickel-content cathodes against degradation and safety issues.
High-nickel-content cathodes have captured the attention of scientists for their high capacity, a chemical property that could power electric vehicles over much longer distances than current batteries support. Unfortunately, the high nickel content also causes these cathode materials to degrade more quickly, creating cracks and stability issues as the battery cycles.
A new lifecycle analysis by researchers at Argonne National Laboratory has found that the carbon intensity of corn ethanol has decreased 23% from 58 to 45 gCO2e/MJ from 2005 to 2019. Their open-access paper is published in the journal Biofuels, Bioproducts and Biorefining. Carbon intensity (gCO2e/MJ undenatured ethanol) of corn ethanol without.

A study conducted by researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory reveals that the use of corn ethanol is reducing the carbon footprint and diminishing greenhouse gases.
The study, recently published in Biofuels, Bioproducts and Biorefining, analyzes corn ethanol production in the United States from 2005 to 2019, when production more than quadrupled. Scientists assessed corn ethanol’s greenhouse gas (GHG) emission intensity (sometimes known as carbon intensity, or CI) during that period and found a 23% reduction in CI.
