Atomic Force Microscopy

Atomic Force Microscopy

Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
The AFM Probe
The probe is regarded as the heart of any AFM setup and comprises the...

Background:

Thin-film lithium-ion batteries are crucial for micro-electronic devices.
Prolonging the operational lifetime of these batteries requires understanding cathode film aging mechanisms.

Purpose of the Study:

To investigate the nanoscale aging mechanisms of lithium-cobalt oxide (LiCoO2) cathode films.
To correlate microscopic surface changes with macroscopic capacity fade.

Main Methods:

Multi-characterization using advanced Atomic Force Microscopy (AFM)-based techniques.
Amplitude Modulation-Frequency Modulation (AM-FM) for surface morphology and contact stiffness.
Kelvin Probe Force Microscopy (KPFM) for surface potential.
Galvanostatic charge/discharge for macro-capacity measurement.

Main Results:

Observed significant changes in surface morphology, contact stiffness, and surface potential after charge/discharge cycling.
Detailed discussion of the intrinsic reasons behind these observed microscopic alterations.
Correlation established between nanoscale changes and macro-capacity degradation.

Conclusions:

The study provides deep insights into the fading mechanisms of LiCoO2 cathode films.
Findings are valuable for the design and selection of cathode materials for high-performance thin-film batteries.
