The distribution of microplastics is often closely related to human activities. In addition to densely populated areas, remote areas have become the focus of research in recent years. The intensity of human activities directly affects the abundance of microplastics. However, the ecological risks of microplastics are also closely related to characteristics such as their particle size, shape, and polymer type. Therefore, it is of great importance to evaluate the impact of environmental factors on microplastic characteristics.
Argonne National Lab researchers have developed a fluorine-containing electrolyte for lithium-ion batteries that optimizes performance in sub-zero temperatures, a development that could improve the charging efficiency of electric vehicles in cold climates.
Scientists have developed a fluorine-containing electrolyte for lithium-ion batteries whose charging performance remains high in frigid regions and seasons. They also determined why it is so effective.
Researchers created a new and safer electrolyte for lithium-ion batteries that performs just as well in subzero temperatures as it does at room temperature.
