摘要：

A Li/SOCl2 bobbin-type cell, connected in parallel with an electrochemical capacitor, is investigated in order to overcome the voltage delay problem at high-rate discharge. In spite of the high internal resistance of the Li/SOCl2 cell due to the passivation, the voltage delay is suppressed. Impedance measurements, in which the cell is separated from the capacitor, explain the suppression process clearly. The electrochemical capacitor operates as a high-current buffer and voltage-delay suppressor for the Li/SOCl2 bobbin-type cell. (C) 2004 Elsevier B.V. All rights reserved.
