Active pore space utilization in nanoporous carbon-based supercapacitors: Effects of conductivity and pore accessibility

▸ Pores smaller than 0.7 nm are the most active in charge storage in carbonaceous materials. ▸ Conductivity of carbon helps in efficient charge transfer to active pores. ▸ Polar groups help in charge transfer to the pores by increasing surface wettability. ▸ Active pore space utilization by DLC is affected by conductivity and wettability.
