چکیده

The parameters determination of the supercapacitors is a required stage in the identification process of the supercapacitors with the applications in which they are integrated. After a short overview on the supercapacitors models, an RC model for a pack of supercapacitors is presented. Between the measurement methods for the supercapacitors parameters, the constant charge method and the capacitance-time domain conversion method are presented. Based on the RC model proposed, parameters determination is made, in a case study that proves the viability of the constant charge method determination.

Enhanced cycling stability of NiCo2S4@NiO core-shell nanowire arrays for all-solid-state asymmetric supercapacitors

As a new class of pseudocapacitive material, metal sulfides possess high electrochemical performance. However, their cycling performance as conventional electrodes is rather poor for practical applications. In this article, we report an original composite electrode based on NiCo2S4@NiO core-shell nanowire arrays (NWAs) with enhanced cycling stability. This three-dimensional electrode also has a...

Measurement Considerations on Some Parameters of Supercapacitors

The paper is focused on identification and measurement of the main parameters of the stacked supercapacitors (SC). The volt-ampere method was used to measure the charge/discharge characteristic, impedance spectroscopy method for measurement of the equivalent serial resistance and analysis of the dynamic parameters. The measured and calculated parameters are: equivalent serial resistance (ESR), ...

Miniaturized Stretchable and High-Rate Linear Supercapacitors

Linear stretchable supercapacitors have attracted much attention because they are well suited to applications in the rapidly expanding field of wearable electronics. However, poor conductivity of the electrode material, which limits the transfer of electrons in the axial direction of the linear supercapacitors, leads to a serious loss of capacity at high rates. To solve this problem, we use gol...

The Supercapacitor Degradation State Diagnostic System Based on LabVIEW

In this thesis, we design and implement the degradation state diagnostic system for supercapacitors. In order to detect the degradation degree of supercapacitors, it is necessary to measure the changes of parameters that include capacitance, ESR (equivalent series resistance) and the leakage current. The way to obtain these parameters is to collect the voltage and current values by the data acq...
