説明

<p>All-solid-state batteries (ASSBs) are expected to be next-generation batteries owing to their safety and suitability for high-temperature operation. While traditional lithium-ion batteries use liquid electrolytes that enable easy electrolyte filling after electrode fabrication, ASSBs use solid electrolyte particles. Thus, electrolyte particles must be dispersed alongside the active materials and additives during electrode preparation. The dispersion state of the electrolyte influences subsequent electrode formation and structure; however, experimentally quantitatively controlling and evaluating the dispersion states remains challenging. This study used powder simulation to control the dispersion state quantitatively, based on the aggregation size of solid electrolyte particles. It also evaluated the compression process and the resulting electrode structure.</p>
