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