HomeDispersions Characterization

Battery dispersions characterization is crucial for evaluating the stability, homogeneity, and performance of dispersions used in battery electrode manufacturing processes. A laboratory specializing in this area can provide valuable insights into the properties and behavior of battery dispersions. Here’s what such a service could offer:

Particle Size Analysis:

  • Measure the size distribution of particles in battery dispersions using techniques such as dynamic light scattering (DLS), laser diffraction, or microscopy.
  • Analyze particle size distribution to assess dispersion homogeneity and its impact on electrode performance and manufacturing consistency.

Zeta Potential Measurement:

  • Determine the zeta potential of dispersed particles to evaluate their electrostatic stability and propensity for aggregation or sedimentation.
  • Assess the influence of surface charge on dispersion stability and interactions with electrolytes and electrode materials.

Rheological Characterization:

  • Analyze the rheological properties of battery dispersions to understand their flow behavior and processability during electrode coating and assembly.
  • Measure viscosity, shear stress, and shear rate dependencies to optimize dispersion formulations for specific manufacturing processes.

Chemical Composition Analysis:

  • Perform spectroscopic techniques such as Fourier-transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR) spectroscopy to identify the chemical composition of battery dispersions.
  • Analyze the presence of functional groups, solvents, dispersants, and additives to ensure compatibility with electrode materials and electrolytes.

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 Analysis:

  • Investigate the surface chemistry of dispersed particles using techniques such as X-ray photoelectron spectroscopy (XPS) and surface titration.
  • Characterize surface functionalities, surface charge density, and adsorption behavior to understand particle interactions and stability in dispersion.

Electrochemical Performance Evaluation:

  • Evaluate the impact of battery dispersions on electrode performance and electrochemical properties using techniques such as cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS).
  • Measure electrode kinetics, charge transfer resistance, and cycling stability to optimize dispersion formulations for enhanced battery performance.

Optical Microscopy and Imaging:

  • Visualize dispersed particles and assess their distribution, morphology, and aggregation using optical microscopy and imaging techniques.
  • Identify particle clustering, agglomeration, or defects that may affect dispersion quality and electrode performance.

Customized Characterization Services:

  • Develop customized testing protocols and methodologies tailored to the specific requirements and objectives of clients and their battery dispersion formulations.
  • Provide consulting services to assist clients in interpreting characterization results and optimizing dispersion formulations for improved electrode manufacturing and battery performance.
