With the aid of chronopotentiometry, voltammetry, and potentiostatic closure, the electrochemical characteristics of lithium intercalation to polyacrylonitrile carbon fiber was determined, namely, the capacitance, kinetic currents, lithium diffusion coefficient, autocharge currents. The study was made at 298 К in 1 M solutions of LiClO4 in some mixed organic solvents (propylene carbonate – dimethoxyethane 7:3, propylene carbonate – diethyl carbonate 3:1).
