ZEISS Microscopy

Perform Battery Research Beyond Electrochemical Analysis

Linking Structure and Chemistry with Microscopy Solutions

Today, electrochemical analysis of lithium ion batteries is the key toolset of battery research. Efforts are targeted to increase life and cycle time, energy density, capacity, and safety and to decrease aging effects, time for charging, overall costs, weight and temperature dependency.

Find out how to complement your toolkit beyond electrochemical analysis – with microscopy solutions for battery research. Imaging techniques, analytics and multi-modal workflows with microscopes let you characterize batteries comprehensively. Gain new insights into the geometric architecture of electrodes inside the battery, quality of nano-particles, chemical composition of polymers – including lithium detection – and much more.

Geometric Architecture

Investigate the geometry of electrodes from embedded battery samples.

  • Inspect the whole bulk quickly with zoom and digital light microscopes
  • Image large areas fast with stereo light microscopes
  • Investigate polished sections and particles at high resolution with widefield light microscopic techniques
  • Characterize micro- and nanometer scaled defects at high resolution with an SEM
  • Image sensitive material like graphite or polymers with low voltage SEM

  • Light Microscopy: ZEISS Axio Zoom, ZEISS Axio Imager
  • Scanning Electron Microscopy: ZEISS GeminiSEM 500

Package Inspection

Perform large-scale inspection of the whole, intact battery package.

  • Profit from non-destructive inspection of the whole, intact battery 
  • Perform 4D evolution studies and characterize a 3D volume at high-resolution over time
  • Investigate the evolution of microstructure over time
  • Spot property changes after several cycles

  • X-Ray Microscopy: ZEISS Xradia Versa Family

Particle Size

Quantify particle sizes, void sizes and tortuosity inside of the battery.

  • Investigate the dilation of particles in situ before and after cycling in e.g. coin cells with X-ray microscopy
  • Calculate tortuosity, a value that describes diffusion and fluid flow in porous media, through a high resolution X-ray scan
  • Analyze solid state electrolyte interfaces by a multi-modal, correlative workflow that combines XRM- with FIB-SEM-investigations: Start with scanning a bigger volume with X-ray microscopy non-destructively; then, navigate to the identified region of interest and perform in-depth analysis utilizing a FIB-SEM and a solution for correlative microscopy

  • X-Ray Microscopy: ZEISS Xradia Versa Family, ZEISS Xradia Ultra Family
  • FIB-SEM: ZEISS Crossbeam Family
  • Multi-modal Workflows: Atlas 5

Chemical Composition

Perform high-resolution imaging to identify the chemical properties of the battery.

  • Investigate polymers or material composition with analytic techniques added to your FE-SEM, such as EDS, EBSD, Raman or AFM or TOF-SIMS
  • Perform in situ experiments, e.g. on temperature dependency, with a heating stage in an SEM
  • Analyze localized chemistry after cycling experiments at your region of interest using multi-modal, multi-scale correlative workflows using LM & SEM & XRM
  • Check the quality of interfaces and Li distribution nano-particles with high resolution in-situ imaging in an FE-SEM
     

  • Field Emission SEM: ZEISS GeminiSEM
  • FIB-SEM: ZEISS Crossbeam Familiy
  • Analytics: EDS, Raman and in situ experiments with Heating Stage
