In article number 1900246, Xingbin Yan and co‐workers present a novel vacuum filtration‐and‐transfer (VFT) technique for the sample preparation of an electrochemical quartz crystal microbalance (EQCM). Compared with the frequently used spray method, the VFT method can effectively reduce the change of resonance width caused by sample inhomogeneity, thereby making EQCM more reliable to distinguish the rigid model from the viscoelastic model, and to clearly describe the energy storage mechanisms of various electrode materials.
