Electrochemical impedance spectra and CV curves of V2O5 nanocrystals

The DataSet contains the EIS spectra for coin-cells and CV curves with the V2O5 nanocrystals obtained by the sol-gel method. Cyclic voltammetry and electrochemical impedance spectroscopy (EIS) were measured using the AUTOLAB 302N potentiostat-galvanostat under Nova software. The EIS measurements were recorded in the frequency range 100 kHz to 10 mHz for the fresh cells after 2, 10, and 15 CV cycles in the voltage range between 2.0 V and 4.0 V vs. Li/Li+ at a scan rate of 1 mV/s. These results are part of a project defined in the RSC Advances journal (10.1039/c6ra05695d). In this paper, the information about sample synthesis and measurement details are reported.
