Semi-batch reactions offer several advantages over traditional batch reactions, such as greater selectivity of products, gradual addition of reactants for better process control, and the ability to isolate product as it is formed.
This application note describes a correlative Raman–scanning electron microscope (SEM) investigation of a lithium-ion battery cathode before and after hundreds of charge cycles. The technique provides an exceptionally detailed chemical and structural analysis of degradation processes on the nanoscale.
Using an automated FT-IR reflection sampling accessory, the surface of a polymer-coated aluminum film was analyzed. Spectral results were used to investigate chemical uniformity across the sample area.
