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
