Abstract
Disclosed herein is an electrode material for a supercapacitor. More specifically, disclosed is a hybrid structure of a high surface area host structure and embedded carbon structure that could be used as the electrode. The embedded carbon can be of activated nature where it contains pores that the electrolyte ions could utilize. The method of activation of the said activated carbon is also disclosed.
