Electronic devices such as MEMS and micro-actuator have been developed by using nanotechnology. It is important to control the surface structure at high precision and speed on an atomic scale, which requires to clarify the dynamics processes at electrode surfaces. This review introduces an overview of in situ studies by two types of high speed scanning probe microscopes. One is the video rate scanning tunneling microscope demonstrating the growth dynamics during metal electrodeposition and surface reconstruction during gas evolution. The electrochemical phenomena can be discussed in tens of milliseconds and atomic resolution. The other is high speed atomic force microscope, presenting polymer adsorption and metal nucleation under less tip effects.

Atomic‐scale processes at electrode surfaces in liquid electrolytes are central elemental steps of electrochemical reactions. Detailed insights into the structure of these interfaces can be obtained with in situ scanning tunnelling and atomic force microscopy. By increasing the time resolution of these methods into the millisecond range, highly dynamic processes at electrode surfaces become directly observable. This review gives an overview of in situ studies with video‐rate scanning probe microscopy techniques. Firstly, quantitative investigations into the dynamic behaviour of individual adsorbed atoms and molecules are described. These reveal a complex dependence of adsorbate surface diffusion on potential and co‐adsorbed species and provide data on adsorbate–adsorbate and adsorbate–substrate interactions in a liquid environment. Secondly, results on collective dynamic phenomena are discussed, such as molecular self‐assembly, the dynamics of nanoscale structures, nucleation and growth, and surface restructuring due to phase‐formation processes.

“…Atomic force microscopy (AFM) is a powerful tool for nano-characterization with high resolution. , Taking advantage of a characteristic tip-surface interaction, various AFM-based techniques have been developed and used to investigate different physicochemical properties of the battery materials. − Among these, electrochemical AFM (EC-AFM) is one of the most widely used AFMs in the battery field because it can in-situ-monitor the evolution of surface/interface morphology during the electrochemical reaction. Furthermore, high-speed EC-AFM (EC-HS-AFM) is a promising tool, which has ability to in situ real-time-observe Cu electrodeposition and dissolution behavior, , dynamic nanobubbles during water electrolysis, and dynamic morphological change of the battery materials with a high-spatial/temporal resolution. , In the previous work, we have successfully developed and utilized our home-made EC-HS-AFM to investigate dynamic morphological evolution during the electrochemical cycle to build a correlation between the changes in the LiMn 2 O 4 particle size and potential …”

Spinel LiMn 2 O 4 is a promising cathode material but suffers from severe capacity fading during battery operation. One of capacity fade mechanisms results from changes in its morphology and structure due to over-discharge. In this work, for the first time, we successfully tracked the morphologic evolution of LiMn 2 O 4 submicron-sized particles during overdischarging by our home-made electrochemical high-speed atomic force microscopy (EC-HS-AFM). Seven hundred and sixty successive EC-HS-AFM images were stably captured at an imaging speed of ∼0.85 fps at corresponding potentials during overdischarging in ∼15 min, from which evolutions of nanoscale wrinkle-like and step-like structures on the particle surface were clearly observed. The phenomena could be resulted from the complex stresses due to structural distortion during the phase transformation from cubic (LiMn 2 O 4 ) to tetragonal (Li 2 Mn 2 O 4 ), and the formation of the Li 2 Mn 2 O 4 phase was confirmed by ex situ XRD. Moreover, the particle surface area as a function of the potential was quantitatively extracted from the EC-HS-AFM images, revealing the irreversible expansion/contraction of the particles, and this finding obtained at the nanoscale was consistent with the macroscopic results tested by cyclic voltammetry and galvanostatic charge/discharge methods. These results demonstrate that the EC-HS-AFM is a powerful tool to establish the correlation between the over-discharge-induced surface morphology changes and irreversibility of the Li-ion insertion/extraction as well as capacity fading.
