[Analysis Case] Component Analysis of Lithium-Ion Secondary Battery Binders
Identification of organic components by pyrolysis GC/MS.
Lithium-ion secondary batteries use a wide variety of materials, ranging from metals and inorganic substances to organic materials, and from solids to liquids. The physical properties and combinations of each material significantly reflect the characteristics and reliability of the device, making accurate analysis and evaluation of the materials necessary. In this study, the anode of the lithium-ion secondary battery was measured using pyrolysis GC/MS (pyro-GC/MS), and it was found that the binder material is based on SBR (styrene-butadiene latex). Additionally, decomposition products of the binder and aromatic substances presumed to be reaction products were also detected.
