Abstract: This dissertation summarized research on the energy storage mechanism and discussed the interaction between the porous structure and the electrolyte ions. What’s more, this review described simply the theoretical models of double electric layer including the previous parallel-plate model, the later EDCC and EWCC models taken into account curvature, and the newest charging mechanisms of EDLCs. Finally, this review concluded that the best approach to achieve high power density and high energy density for porous carbon based supercapacitors will be to synthetize the porous carbon which owns the optimal micropores size and appropriate proportional of mesopores.

Key words: electrochemical double-layer capacitors (EDLCs), energy storage mechanism, models of double electric layer
