Abstract
A quantitative analysis of laser-induced breakdown spectroscopy (LIBS) for lithium iron phosphate (LFP) electrodes was established to study the three-dimensional elemental concentration distribution and to optimize electrode architecture. Due to the characteristic flat voltage curve of LFP, a full-cell model was applied for electrochemical titration, enabling the validation of quantitative calibration model on state of lithiation using IR laser radiation. To further enhance analytical throughput, a laser repetition rate of 500 Hz was applied, demonstrating the potential for high-speed, spatially resolved analysis.
