Battery performance is shaped by materials at every stage. When a material, component, or cell behaves differently than expected, characterization can help reveal why.

*The Battery Scientist’s Characterization Toolkit* explores analytical workflows for active materials, electrodes, electrolytes, separators, complete cells, and failure analysis.
