LiNiO2 cathode powder

Cathode Active Material (CAM) is used for rechargeable lithium-ion batteries. The in-situ study of the powder particles' conductivity was required in order to prolong the battery lifetime


The coating was applied to protect particles from unwanted reactions. A combination of SEM, AFM and C-AFM techniques revealed that the edges of the particles were the most conductive areas. 


Measurement modes: C-AFM, Topography


Litescope benefits:

  • in-situ analysis of air-susceptible samples 
  • correlated and time-efficient SEM, AFM and C-AFM analysis
  • precise grain identification
