Abstract Hierarchical porous carbon nanoparticles, with tailored asymmetric morphologies and pore structures, have great implications in high‐performance electrode materials. However, the controlled synthesis of anisotropic nanoparticles multimodal structures remains a challenge. Herein, droplet‐directed assembly approach to synthesize macro/mesopores is demonstrated. This relies on growth mesoporous polydopamine (PDA) seeds emulsion interfaces subsequent immersion 1,3,5‐trimethylbenzene (TMB) droplets into seeds. The obtained present semifootball‐shaped morphology high surface area (383 m 2 g −1 ), well‐controlled macropores (≈105 nm), mesopores (≈3.8 nm). By tuning polarity oil phase, transform from non‐porous spheres semifootball‐like architectures finally nano‐ellipsoid meso‐channels. are further optimized by ZnCl activation, modulated compositions deliver reversible capability, excellent rate performance (215 F at 0.05 A 143 20 organic electrolyte), enhanced energy density (53.4 Wh Kg ). Simulation results elucidate structure–activity relationship between multistage structure electrochemical performance, i.e., hierarchy enhances ion diffusion flux, large‐mesopore facilitates performance.
