Carbon, Sulfur, Oxygen & Nitrogen Analysis for Battery Materials

Battery materials analysis requires precision, repeatability, and defensible methods. From lithium-ion battery manufacturing and EV component quality control to black mass recycling and graphite purity testing, accurate material characterization directly impacts performance, safety, and regulatory compliance.

For decades, LECO has delivered trusted analytical solutions across energy sectors including coal, petroleum, and nuclear. That expertise now supports lithium battery testing, lithium iron phosphate (LFP) analysis, carbon and sulfur analysis in battery materials, and elemental analysis for advanced battery chemistries.

Our methods align with recognized industry standards to ensure reliable and reproducible results:

  • ASTM C561 and ASTM C562: With modifications for macro TGA analysis to determine moisture and ash in battery materials (graphite).

These standardized and adapted approaches provide confidence in quality control, raw material verification, and recycling workflows across the battery lifecycle.

Our core analytical solutions include:

  • Purity & Quality Control (SC832DR): High-precision carbon and sulfur analysis to detect trace contaminants in anodes, cathode precursors, and critical battery materials.
  • Sustainability & Black Mass Recycling Analysis (TGA801): Automated moisture and ash analysis to support recovery optimization, sustainability initiatives, and process control.
  • Analysis for Advanced Battery Chemistries (CS744/CS844/ON836): Reliable testing for LFP, Li-NMC, and next-generation materials in both production and R&D environments.

Let us empower your lab with rapid, reliable results and the unmatched service and support we’re known for. Explore our resources below to see how LECO can help you meet your battery materials industry demands with confidence.
