In this work, we studied the graph of impedance spectroscopy of a solid polymer electrolyte at room temperature for lithium-ion batteries and its temperature dependence. When studying solid polymer electrolytes, Nyquist coordinates and electrochemical impedance spectroscopy were used. The ionic conductivity of the electrolyte was 6.39 · 10−6 1/OM·CM at 303 K and 1, 07 · 10−4 1/OM·CM at 373 K. Maximum conductivity electrolyte based on LiTf2 was 3, 075 · 10−5 1/OM·CM , which was achieved with a sample thickness of 0.033 cm.
