摘要：

Composite V6O13 electrodes were characterized in cells having metallic lithium counter and reference electrodes. The overall impedance changes closely follow the variation of the V6O13 unit cell volume. An abrupt change in unit cell volume if reflected in a corresponding abrupt change in the interfacial impedance. The variation of the interface impedance implies that the integrity of the electrode structure changes during the lithium insertion and extraction processes.
