For in-situ microscopic observations, we used an optical microscope (OM, Xi’an Cewei Optoelectronic Technology Co., Ltd) and electrochemical workstation (CHI 660E). The electrical and thermal conductivities of graphene film were measured by four-point probe system (RTS-9) and LFA467 Hyper ...
The electrochemical impedance spectroscopy (EIS), galvanostatic charge-discharge (GCD), and cyclic voltammetry (CV) were characterized by CHI660E electrochemical workstation (Shanghai Chen-hua instrument co. LTD). Results and Discussion As shown in Fig. 1, the conductive scaffold was formed by the...
Li+/Li). The measurements of cyclic voltammograms (CV) and electrochemical impedance spectroscopy (EIS) were conducted on a CHI660E electrochemical workstation (CHENHUA, China). CV curves were recorded in a potential window of 2.5–4.3 V (vs. Li+/Li) at scan rates of 0.2 to 0.5 mV...
The electrochemical performance was investigated using cyclic voltammetry (CV), differential pulse voltammetry (DPV), and electrochemical impedance spectroscopy (EIS) with a CHI 660E electrochemical workstation (Shanghai Chenhua Instrument Co., Ltd.). In a three-electrode system, a graphene/Ta wire ...
The cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) measurements were performed on a CHI660E electrochemical workstation. The CV curves were investigated on a scanning rate of 0.1 mV s-1, while the EIS were measured at the frequency ranged from 0.01 Hz to 10 kHz....
The electrochemical measurements were performed using a CHI660 electrochemical workstation (Chenhua Instruments Co., Shanghai, China). A conventional three-electrode configuration was used, consisting of a bare glassy carbon electrode (GCE) (diameter 3.0 mm) or a fabricated HIV sensor working electr...
Electrochemical measurements including EIS and CV were performed on a CHI 660D electrochemical workstation (CH Instruments, Chenhua, Shanghai, China) with a conventional three-electrode system composed of a modified electrode as a working electrode, a platinum wire as an auxiliary electrode and ...
Three-electrode set up connected to CHI 660E workstation (CH Instruments, China) and controlled by CHI 660E software was used to make electrochemical measurements. Three electrode configurations consist of the CNFs-SBE-β-CD-modified glassy carbon electrode, platinum, and Ag/AgCl (3 M KCl) as...
The potentiodynamic polarization tests were conducted in the 3.5% NaCl solution using the CHI660E electrochemical workstation. The result shows that there are three zones in the brazing joint: Athermally Solidification Zone (ASZ), Isothermally Solidified Zone (ISZ) Diffusion Affected Zone (DAZ). A...
All electrochemical measurements were operated on a CHI-660A electrochemical workstation (Chenhua Apparatus Co., Shanghai, China) with the conventional three-electrode system. The unmodified or modified GCE, platinum wire, and saturated calomel electrode (SCE) were respectively used as the working ...
