I think: Two reasons, bad overlapping orbitals due vibrattions and high electron population in conduction band will decrease conductivity in metals if you increase T.

You may have two concepts mixed in your post: electrolyte (liquid) and electrical conductor (solid). The dependency of conductance on temperature is not quite so simple as you suggest, depending on just what you meant.

In chemistry, an electrolyte is any substance containing free ions that make the substance electrically conductive. The most typical electrolyte is an ionic solution, but molten electrolytes and solid electrolytes are also possible. Electrolytes commonly exist as solutions of acids, bases or salts

If this is what you really meant, then the conductivity generally INCREASES with temperature because the free ions can move more easily in liquid..they are mort thermally active. Most chemical reactions take place more readily at higher temperatures. That's why automobile batteries, for example, produce more power in warm rather than cold temperatures. In fact CCA (cold cranking amps) is a measure of how well a battery produces power at zero degrees farenheit because they are much weaker as temperatures decline substantially.

For solid conductors, Wikipedia shows this:
Electrical conductivity is strongly dependent on temperature. In metals, electrical conductivity decreases with increasing temperature, whereas in semiconductors, electrical conductivity increases with increasing temperature

http://en.wikipedia.org/wiki/Electrical_conductivity#Temperature_dependence

but there are exceptions:
At extremely low temperatures (not far from absolute zero), a few materials have been found to exhibit very high electrical conductivity in a phenomenon called superconductivity.
