¿µ¹®³»¿ë¿ä¾à This standard recommends to use ionic conductance as a criteria of the performance analysis of solid electrolyte in all kinds of solid secondary batteries. The principle and analysis of ionic conductivity of solid electrolyte are mainly introduced since ionic conductance in solid shows the different behavior from that in liquid. Also, ionic conductivity is determined by the result of Nyquist plot analysis which is done on the impedance output drawn by the standardized measuring method.
