As demand for energy storage increases, the need for safe, powerful, and reliable batteries is greater than ever before. However, the safety, performance, and lifetime of a battery will only be as good as the materials that go into making it. Raw materials for batteries need to be fully characterized and monitored from the time they enter the production facility, as they are being incorporated into battery components and cells, and until they are incorporated into the final product. Additionally, monitoring how battery materials change over the course of the battery lifetime, as well as active metal content related to battery recycling, is critical.
This e-book is a practical, downloadable, field guide on how to best characterize a wide range of novel battery materials with an end goal of developing lithium-ion batteries with improved energy storage, performance and safety. Specific battery materials that are discussed include powdered anode and cathode materials, electrode slurries, separators/current collectors, and liquid electrolytes.
Specific measurement techniques for solid electrode materials include particle size analysis by laser diffraction and dynamic light scattering, surface area and pore size analysis by gas sorption, powder density analysis by gas pycnometry, in-situ crystal structure analysis by XRD, instrumented scratch testing, and microwave-assisted acid digestion for sample preparation prior to elemental analysis.
Techniques for electrode slurries include slurry flow properties analysis and curing with rheology, and liquid density determination, as well as percent solids analysis, by gas pycnometry.
Techniques for analyzing battery separators include pore size analysis with flow porometry, mercury porosimetry, and structural property analysis with DMA. Finally, techniques for analyzing battery electrolytes include viscosity and density analysis.
The e-book includes real-life examples, applications and measurement data and shows the benefits of thoroughly measuring and characterizing battery materials.
