From: An aqueous electrolyte of the widest potential window and its superior capability for capacitors
(1) XRD patterns in the negative (a) and positive (b) electrode for a capacitor consisting of 10% of V2O3 in the negative electrode and GA in the positive electrode. The samples were taken after the charge. (2) XPS spectra for carbon 1 s of graphite. The sample were taken in the same way as in Fig. 6(1) under the same condition. Because of the large 1 s signal of perchlorate oxygen, the S/N ratio of the sample signals are lower compared with the standard peak of original graphite (green). The red peak corresponds to the negative electrode and blue one positive electrode, respectively.
