HomePowder Characterization

Battery powder characterization services are vital for assessing the properties and suitability of powders used in battery electrode manufacturing. Here’s a breakdown of what a laboratory specializing in this area could offer:

Particle Size Analysis:

  • Utilize techniques such as laser diffraction, sieve analysis, or microscopy to measure the particle size distribution of battery powders.
  • Provide information on particle size distribution, median particle size, and particle size uniformity, which are critical for optimizing electrode performance and manufacturing processes.

Surface Area and Porosity Measurement:

  • Determine the specific surface area and pore size distribution of battery powders using methods like BET (Brunauer-Emmett-Teller) analysis or mercury porosimetry.
  • Assess the porosity and surface area characteristics of powders to understand their impact on electrolyte penetration, ion transport, and electrode performance.

Chemical Composition Analysis:

  • Perform techniques such as X-ray fluorescence (XRF), X-ray diffraction (XRD), and spectroscopic methods (e.g., FTIR, Raman) to analyze the chemical composition and crystal structure of battery powders.
  • Identify the presence of active materials, impurities, phase compositions, and crystallographic phases to ensure powder quality and suitability for battery applications.

Particle Morphology and Shape Analysis:

  • Evaluate the morphology, shape, and surface features of battery powders using scanning electron microscopy (SEM) or transmission electron microscopy (TEM).
  • Characterize particle morphology parameters such as aspect ratio, surface roughness, and particle agglomeration to optimize electrode processing and performance.

Stability Testing:

  • Assess the stability of battery dispersions under various storage conditions, including temperature, humidity, and time.
  • Monitor changes in particle size distribution, zeta potential, and rheological properties to identify destabilization mechanisms and optimize dispersion formulations.

Surface Chemistry and Functional Group Analysis:

  • Investigate the surface chemistry and functional groups present on the surface of battery powders using techniques like X-ray photoelectron spectroscopy (XPS) and Fourier-transform infrared spectroscopy (FTIR).
  • Assess surface functionalization, surface charge, and chemical interactions to understand powder behavior during electrode processing and electrochemical reactions.

Thermal Analysis:

  • Perform thermal analysis techniques such as differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) to evaluate the thermal stability, decomposition behavior, and phase transitions of battery powders.
  • Determine thermal properties such as melting points, decomposition temperatures, and heat capacities to ensure powder stability during electrode processing and battery operation.

Mechanical Properties Testing:

  • Assess the mechanical properties of battery powders, including hardness, compressibility, and flowability, using techniques such as powder rheometry and bulk density measurements.
  • Optimize powder formulations and processing parameters to enhance electrode compaction, coating uniformity, and overall battery performance.

Electrochemical Characterization:

  • Evaluate the electrochemical properties and performance of battery powders using techniques such as cyclic voltammetry (CV) and galvanostatic cycling.
  • Measure parameters such as specific capacity, rate capability, and cycling stability to assess the suitability of powders for battery electrode applications.
