China cracks EV battery puzzle, paving way for cheaper, long-range lithium cells
Researchers at Tsinghua University used advanced X-ray computed tomography to study the relationship between electrode microstructure and electrolyte wetting in batteries, aiming to improve ion movement and create stable, high-energy density batteries on a large scale. The research highlighted the impact of manufacturing processes on wetting behavior, including reduced electrode porosity and trapping of non-wetting phase gases. Insights from this study can lead to improved production processes, cost reduction, and advancements in battery technologies for...
