Inductive Impedance of a Spirally Wound Li / MoS2 Cell

Abstract

The impedance of cylindrical lithium molybdenum disulfide cells has been measured in the frequency range of 1 kHz to 10 MHz. In this frequency range, it is shown that the inductance associated with the spiral geometry of the cell electrodes contributes significantly to the cell impedance. It is also shown that the resistive component of the impedance at high frequency is attributable in part to damping of induced currents in the can and central mandrel of the cell, and to radial ion flow between electrodes in the spiral winding.
