Battery Materials
Battery performance and safety depend on tightly controlled chemistry at surfaces, interfaces, and trace impurity levels. Battery materials are widely used across lithium-ion and emerging chemistries (project-dependent) in applications such as consumer electronics, electric vehicles, energy storage systems, and industrial power. Small variations in composition, moisture/ionic contamination, particle morphology, and surface chemistry can drive major impacts on capacity retention, impedance growth, gas generation, and cycle life.
We provide analytical testing and materials characterization for battery active materials, electrolytes (project-dependent), separators/binders, conductive additives, coatings, and failure-related residues, supporting R&D, supplier qualification, incoming QC, process monitoring, and root-cause investigations. Our multi-technique approach delivers clear, decision-ready results—especially for “what changed?” comparisons and contamination source identification.
Why Testing Matters for Battery Materials
Battery materials are sensitive to impurities and surface chemistry. Common analytical needs include:
Composition and stoichiometry control for consistent electrochemical performance
Phase identification and structural changes affecting capacity and stability
Trace metals and ionic contamination that drive parasitic reactions and impedance growth
Surface chemistry and coatings that govern interfacial behavior (CEI/SEI-related questions)
Moisture/volatile-related risk indicators (project-dependent)
Thermal stability and decomposition behavior linked to safety and gas generation (project-dependent)
Particles, residues, and cross-contamination across manufacturing steps
Our lab uses orthogonal methods to build an evidence-based view of what changed and why it matters.
FAQs
Can you support both cathode and anode materials?
Yes (project-dependent). We can tailor methods based on the chemistry and required limits.
Do you provide spec-based pass/fail reporting?
Yes—provide limits and any preferred method references, and we’ll align reporting accordingly.
Can you detect ultra-trace metals and ions?
Often yes, depending on matrix and limits. We’ll recommend the best method (ICP-MS, TXRF, IC) based on your requirement.
Can you evaluate surface coatings or interfacial chemistry?
Yes (project-dependent). XPS/TOF-SIMS is commonly used for surface state and residue comparisons.
How important is a reference sample?
Very. A known-good lot enables faster and more defensible “what changed?” conclusions.
Are these analyses destructive?
Most are minimally destructive, but some steps (e.g., depth profiling, certain prep) can be destructive in the analyzed area. We’ll clarify in the method plan.
