Chemical heterogeneity is a significant factor in the performance of all-solid-state batteries such as those composed of garnet-type Li7La3Zr2O12 (LLZO) solid electrolytes. The Applied Spectra J200 Laser Induced Breakdown Spectroscopy (LIBS) Instrument has recently been demonstrated to effectively analyze the elemental composition of LZZO samples, detecting variations in elemental distribution throughout the sample.
The J200 LIBS Instrument is capable of detecting multiple elements with a single pulse. Analysing this data with Applied Spectra’s ClarityNeXtTM software allows the creation of 2D and 3D elemental maps, detecting heterogeneity in LLZO samples which can indicate coating defects, poor mixing of lithium salts, impurities like lithium zirconium oxide, or other effects which impair the performance of the battery. In addition, the J200 LIBS Instrument’s high speed enables rapid, in-situ measurements of chemical heterogeneity, making it possible detect variations in elemental distribution and make timely process adjustments. These capabilities make it suitable for both the development of novel battery chemistries and quality control processes in existing production systems.
