FlexSEM 1000 II
Best-in-class resolution in a compact system. The FlexSEM employs a newly designed electrical optical system with a reliability-proven high-sensitivity detector, achieving imaging at 4 nm.
With a range of characteristics such as fluid, sheet and powder, their complex balance needs to be assessed, controlled and observed before, during and after assembly.
Lithium-ion battery materials are highly sensitive to air exposure. It’s not feasible to establish an assembly line where the product is isolated from the atmosphere, therefore a glovebox is used that ensures the material is not fragilized during the analysis process.
Several factors are significant in this complex process and we can provide the solution you need.
- Fine Raw material structure (down to the atomic level)
- Power coating thickness
- Internal structure and elemental distribution mappings
- Homogeneity of solid state electrodes
- 3D volume analysis
- Chemical analysis if SEM is not enough
SU3800 & SU3900
SU3800 & SU3900 SEM incorporates new Intelligent Filament Technology which allows the user to work with a constant and extremely stable emission current for all acceleration voltages.
SU3900 is more adapted for large samples.
SU5000
Schottky FE-SEM allows for a simple transition between high vacuum and variable pressure mode. EM Wizard is a knowledge-based system for SEM imaging that goes beyond basic preset conditions and recipes.
SU8600
Ultra high-resolution cold-field emission scanning electron microscopes. Bringing imaging, automation, increased system stability for efficient workflows.
SU7000
FE SEM ultra high-resolution for wide-area observation, in-situ analysis, variable pressure, high-resolution imaging at low accelerating voltages, and simultaneous multi-signal collection.

Anode Inspection observed on W-SEM FlexSEM 1000 II
Foreign particle inclusions
Critical, as they might punch separators and
cause failure.
Separator observed on FE-SEM
Separators exhibit very beam-sensitive ultra-fine fibril structures, which are easily altered or damaged during SEM inspection, Serial Frame Capture allows proper image.
