Hidden electrical imbalances at the boundaries between tiny crystals of electrolyte material create local electric fields that block lithium ion movement and cause electron leakage, which reduces lithium ions into metal dendrites that short-circuit batteries. Using electron microscopy, machine learning modeling, and electrochemical impedance spectroscopy on LLZO electrolyte material, the team developed a model explaining the space charge behavior at grain boundaries. By adjusting material processing conditions to minimize negative charges at boundaries, they achieved a critical current density more than 300% higher than baseline, enabling faster charging and longer battery life. The findings provide a roadmap for engineering grain boundaries to improve solid-state battery safety and performance. ## Full article daily.dev links to this article rather than hosting it.
