High　performance　supercapacitors　are　significant　for　the　practical　application　of　the　novel　renewable　energies.　Comparisons　suggest　that　hybrid　supercapacitor　(HSC)　is　a　fairly　promising　type　for　application　since　it　combines　high　power　density　and　high　energy　density.　In　this　study,　hierarchically　porous　carbons　(HPCs)　supported　Ni@C　nanoparticles　(Ni@C/HPCs)　were　obtained　by　pyrolyzing　the　precursors　of　Ni-based　MOF/porous　polymers　(Ni-MOF/polyHIPEs)　which　were　prepared　by　high　internal　phase　emulsion　(HIPE)　polymerization　followed　with　solvothermal　Ni-MOF　growing.　The　composition　and　morphology　of　the　Ni@C/HPCs　can　be　controlled　by　changing　the　growth　time　of　Ni-MOF.　The　optimized　sample　Ni@C/HPC-15　demonstrates　a　high　specific　capacity　of　215.0　C　g−1　at　1　A　g−1　and　a　high　rate　performance　of　82.3%　when　the　current　density　increases　from　1　A　g−1　to　10　A　g−1.　Furthermore,　Ni@C/HPC//HPC　HSC　was　assembled　and　achieved　an　energy　density　of　40.9　Wh　kg−1　at　a　power　density　of　747.2　W　kg−1.　In　particular,　the　assembled　HSC　exhibited　a　remarkable　initial　capacitance　retention　of　86.3%　after　5000　cycles　at　6　A　g−1.　The　reported　convenient　method　may　provide　inspiration　in　the　preparation　and　optimization　of　HPC-based　electrode　materials　with　satisfactory　performances　for　energy　storage.　©　2023
