Hierarchically porous graphite particles are synthesized using a continuous, scalable aerosol approach. The unique porous graphite architecture provides the particles with high surface area, fast ion transportation, and good electronic conductivity, which endows the resulting supercapacitors with high energy and power densities. This work provides a new material platform for high‐performance supercapacitors with high packing density, and is adaptable to battery electrodes, fuel‐cell catalyst supports, and other applications.
