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.
- 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
- 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
- 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
- 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
