Battery materials characterization
Battery characterization combines analytical techniques and battery testing to understand material composition, structure, impurities, particle properties, degradation, performance and safety. HORIBA solutions support characterization across the battery value chain, from raw materials and electrodes to cells, modules, packs, second life and recycling..
In this webinar, HORIBA experts introduce a comprehensive approach to battery characterization across the full value chain, from raw materials and active materials to electrodes, cells, modules and complete battery packs, as well as second-life and recycling applications.
Discover how complementary analytical technologies can investigate key battery parameters including elemental composition, impurities, crystallinity, particle size and morphology, electrode uniformity, separator composition and battery aging.
The webinar introduces techniques including Raman microscopy, GD-OES, ICP-OES, C/S and O/N/H analysis, particle size analysis and surface area measurement, before moving from material characterization to integrated cell, module and pack testing under realistic operating and environmental conditions. Battery testing at these different levels addresses electrochemical performance, cycling, balancing, thermal behavior, state of charge, state of health and safety.
The webinar provides an introduction to a broader battery characterization series exploring how analytical measurements can help researchers and manufacturers connect material properties, manufacturing processes, battery performance, degradation and lifetime.

Battery characterization combines electrochemical, chemical, structural and physical measurements to understand battery materials and performance. It can include analysis of composition, impurities, crystallinity, particle properties, electrode structure, capacity, resistance, aging, safety and lifetime.
Different techniques provide complementary information. Raman microscopy investigates chemical composition, crystallinity and material distribution; GD-OES provides elemental depth profiles; ICP-OES measures elemental composition and trace impurities; particle analyzers determine particle size and distribution; and dedicated elemental analyzers quantify carbon, sulfur, oxygen, nitrogen and hydrogen. The webinar emphasizes that these complementary measurements help explain electrochemical results rather than simply measuring performance.
Raman microscopy provides information about the chemical and structural properties of battery materials. It can evaluate carbon crystallinity, characterize electrode components, map their distribution and investigate structural changes associated with battery cycling and degradation. The webinar also presents Raman imaging as a way to assess component distribution within electrodes.
Elemental analysis can identify major elements and trace impurities that influence battery performance, safety and lifetime. Techniques such as ICP-OES, GD-OES and C/S/O/N/H analysis provide complementary information on composition, contamination and elemental distribution.
Particle size, size distribution and morphology influence properties such as packing density, electrode coating uniformity, ion transport and accessible surface area. Monitoring these parameters therefore helps optimize battery material processing and electrode manufacturing.
Battery aging involves multiple chemical and physical processes occurring during repeated charge and discharge cycles. Raman analysis and elemental depth profiling can help investigate structural changes, material migration, interface evolution and degradation mechanisms associated with capacity loss and increased resistance.
Cell testing focuses on electrochemical performance, cycling, degradation and safety. Module testing adds cell balancing, heat distribution and system controls, while pack testing addresses overall voltage, current and power performance, thermal management, state of charge and state of health.
Battery analysis can help determine whether used cells are suitable for reuse by evaluating their state of health. For batteries entering recycling, determining the metal content of black mass can help assess its value and select appropriate recycling processes.
