Scalable Self‐Propagating High‐Temperature Synthesis of Graphene for Supercapacitors with Superior Power Density and Cyclic Stability

An ultrafast self-propagating high-temperature synthesis technique offers scalable routes for the fabrication of mesoporous graphene directly from CO2. Due to the excellent electrical conductivity and high ion-accessible surface area, supercapacitor electrodes based on the obtained graphene exhibit superior energy and power performance. The capacitance retention is higher than 90% after one million charge/discharge cycles. As a service to our authors and readers, this journal provides supporting information supplied by the authors.
