摘要：

This work presents results of measurements of electrical conductivity, thermoelectric power and thermal properties of manganese spinel samples deintercalated in two different ways-an electrochemical and chemical one. It was shown that different methods of lithium extraction lead to striking differences in electrical properties of the obtained LixMn2O4 samples what agrees with the observed differences in their structure as seen by XRD.
