General Method

A summary is given of the authors’ recent research on viscoelastic theory and its application to colloid probe atomic force microscopy. A general computational approach for the interaction of viscoelastic colloids interacting with realistic surface forces of extended range is outlined, and the origins of velocity- and time-dependent effects including hysteresis are discussed. A general method for establishing the zero of separation in atomic force microscopy of deformable bodies is described and utilized in force measurements made on viscoelastic poly(dimethylsiloxane) colloid particles. A quantitative analysis of the velocity and load dependence of the hysteresis in the measurements yields the viscoelastic parameters of the colloid.

This manuscript propose the operando detection technique of the physical properties change of electrolyte during Li-metal battery operation.The physical properties of electrolyte solution such as viscosity (η) and mass densities (ρ) highly affect the feature of electrochemical Li-metal deposition on the Li-metal electrode surface. Therefore, the operando technique for detection these properties change near the electrode surface is highly needed to investigate the true reaction of Li-metal electrode. Here, this study proved that one of the atomic force microscopy based analysis, energy dissipation analysis of cantilever during force curve motion, was really promising for the direct investigation of that. The solution drag of electrolyte, which is controlled by the physical properties, is directly concern the energy dissipation of cantilever motion. In the experiment, increasing the energy dissipation was really observed during the Li-metal dissolution (discharge) reaction, understanding as the increment of η and ρ of electrolyte via increasing of Li-ion concentration. Further, the dissipation energy change was well synchronized to the charge-discharge reaction of Li-metal electrode.This study is the first report for direct observation of the physical properties change of electrolyte on Li-metal electrode reaction, and proposed technique should be widely interesting to the basic interfacial electrochemistry, fundamental researches of solid-liquid interface, as well as the battery researches.
