Abstract

EQCM (Electrochemical Quartz Crystal Microbalance) measurement during Sn(II)/Sn electrode reaction in a room-temperature ionic liquid was conducted using an impedance method EQCM, which can measure the resonance resistance and frequency simultaneously. The mass increased during Sn deposition and decreased during Sn dissolution. The viscosity and density of the electrolyte near the electrode, ηLρL, can be estimated by monitoring the resonance resistance. The change of the ηLρL value during Sn(II)/Sn electrode reaction could be accounted for by the concentration profile of Sn(II) near the electrode.
