CMK-5-Based High Energy Density Electrical Double Layer Capacitor for AC Line Filtering.

ABSTRACT: Compact electrical double layer capacitors (EDLCs) can be applied to the AC line filtering process and potentially replace conventional bulky aluminum electrolytic capacitors. However, to realize the AC line filtering application, the energy density of the EDLCs needs to be significantly increased while high power density is maintained. In this work, we demonstrate the EDLCs fabricated with ordered mesoporous carbon, CMK-5, and small amounts of single walled carbon nanotubes (SWNTs), which exhibit the highest areal energy density among various EDLCs reported so far and power performance sufficient for AC line filtering. High energy density of CMK-5/SWNT EDLCs can be attributed to high capacitance arising from the bimodal mesoporosity of CMK-5 and high operation voltage owing to the pores c
