About this technology
Overview
Dendrite growth in lithium-ion batteries can lead to fires and explosions, limiting battery life and safety. High resolution radiographs can be used to detect subtle precursors to battery failure, but it can be tedious to collect and combine these radiographs over the course of testing many battery samples. NASA researchers developed a novel technique for creating unique orientation fingerprints on battery samples prior to digital radiograph collection. The fingerprints enable rapid assembly of high-resolution images. This allows efficient inspection of batteries for early signs of dendrite formation, improving safety and extending useful battery life. This technology can improve efficiency in battery R&D, battery production, and other electronics applications.
