why graphite ( carbon ) rods are used as electrodes in …
2011/9/15· Carbon - the most important reason is that graphite conducts electricity! As for LiCl, it will conduct as it cools down to the freezing (melting) point. If it conducts after that, it is because lithium metal is now short-circuiting the electrodes.

The electricity must flow through electrodes dipped into the electrolyte to complete the electrical circuit with the battery. Electrolysis can only happen when the circuit is complete, and an electrical current (electricity) is flowing, then the products of electrolysing molten lead(II) bromide are released on the electrode surfaces where they can be collected.
