Embodiment 1
[0074] 0.2 g of cylindrical LiMn with a length of 500 nm and a diameter of 100 nm was prepared by dispersing in ethanol 2 O 4 . In another beaker, 0.012 mmol of pyrrole, 0.012 mmol of hydrochloric acid, and 50 mL of ethanol were stirred to protonate the pyrrole.
[0075] Then, the protonated pyrrole was added to LiMn 2 O 4and stir. At this time, the protonated pyrrole with positive (+) charge is adhered to LiMn with negative (-) charge by electrostatic attraction 2 O 4 on the surface.
[0076] Subsequently, FeCl was added as a polymerization initiator 3 , and the protonated pyrrole was polymerized at 25 °C for 6 h to 2 O 4 A metal oxide comprising a coating composed of a conductive polymer is formed on the surface of the .
Embodiment 2 to Embodiment 6
[0078] The conductive polymer-coated metal oxides of Examples 2 to 6 were prepared in the same manner as in Example 1 except that the monomers and hydrochloric acid shown in Table 1 and their contents were used.
