Battery Materials Testing & Analysis

Battery Materials Testing & Analysis

Battery performance is determined by the materials used long before a cell is assembled. Factors such as electrode composition, particle size, surface area, coating quality, and trace impurities all influence capacity, cycle life, and safety. MatX Lab helps analyze battery materials to verify electrode and electrolyte composition, measure particle size and surface area, confirm crystal structure, and investigate the causes of capacity loss or material degradation. Our analysis provides insight into the active materials at the level where battery performance is defined.

What We Analyze in Battery Materials

Battery material testing looks at what the material is made of, how it is structured, and how its particles behave. We check the composition and purity of active materials, measure particle size and surface properties, confirm crystal phase, and identify the reasons behind material degradation. The same testing methods used to assess incoming materials can also help explain capacity loss, performance changes, and battery failures.
Electrode and electrolyte composition and stoichiometry.

• Trace metal and moisture contamination.
• Particle size, morphology, and surface area.
• Crystal phase and structure of active materials.
• Coating and surface chemistry, including SEI layers.
• Degradation and capacity-loss mechanisms.

How We Test Battery Materials

Battery work usually combines composition and structure with particle and surface characterization, and we scope the combination your question needs. The methods below are the ones we reach for most, and each links to its own page.

Elemental Analysis:

Checks the composition of electrode and electrolyte materials, including material ratios and trace metal impurities, using ICP-MS and related techniques. Even small changes in composition can affect battery capacity, performance, and safety.

Structural Characterization:

Identifies the crystal phase and structure of cathode and anode materials by X-ray diffraction. It confirms the active phase and detects unwanted phases that hurt performance.

Particle Analysis:

Measures the particle size distribution and surface area of active materials using techniques such as laser diffraction and gas adsorption. These properties play an important role in battery performance, charge rate, and electrode processing.

Imaging & Microscopy:

Examines electrode morphology, particle structure, coating uniformity, and cross-sections by SEM/EDX or TEM. It shows how the electrode is built and where it degrades.

Surface Analysis:

Characterizes surface chemistry, coatings, and solid-electrolyte-interphase layers by XPS, which drive cycle life and safety.

Thermal Analysis:

Measures the thermal stability and decomposition behavior of electrode and electrolyte materials using DSC and TGA analysis. This helps assess material performance, stability, and safe handling conditions.

Failure Analysis:

Determines the materials-level root cause of capacity loss, shorting, or degradation, combining structure, composition, and imaging.
