The paper presents the results of studying the polarization relaxation mechanism in solid electrolyte LiPON by the method of discharge through an external load. Test cells made in the form of encapsulated multilayer structures SiO 2 /Pt/LiPON/Pt/Ti/SiO 2 /Si were tested on a stand for discharge characteristics measuring. To explain the discharge curves, an equivalent LiPON circuit and a mathematical model of polarization relaxation during discharge are proposed. By fitting the parameters of a mathematical model, the Maxwellian relaxation times of lithium ions and that of the LiPON ionic polarization relaxation are determined.
