Abstract
Electric double layer (EDL) is a kind of interfacial phenomenon. The Phenomenon is known to have huge capacitance. The purpose of the present study is analysis of behavior of ions in electric double layer. For this purpose, we measured capacitance of EDL in 5 wt% NaCl solution at room temperature using step voltage and ramp voltage. We also observed characteristics of EDL at low temperature. We obtained following results. The capacitance by the ramp voltage is about ten times larger than that by the step voltage. EDL is kept in frozen NaCl solution after short-circuiting. Capacitance of frozen EDL is larger than that of liquid EDL at room temperature.
