Answer:
Carbon
Step-by-step explanation:
Carbon is a non metal but Graphite is a pretty good conductor of electricity which is an allotrope of Carbon. There are delocalised electrons which are free. These are responsible for conduction.
These arise because each carbon atom is only bonded to 3 other carbon atoms. The structure of Graphite provides for this arrangement. This leaves 1 electron to become delocalised.
Thus Graphite can be used for electrodes in batteries and for electrolysis.
