The　urgent　demand　for　high-performance　energy　storage　components　has　been　driving　the　exploration　for　superior　battery-type　electrode　materials　for　hybrid　supercapacitors,　which　is　challenging　but　of　considerable　significance.　In　this　paper,　a　one-step　pyrolysis　route　was　elaborated　to　prepare　oxygen-enriched　hierarchical　porous　carbon　supported　Co-Ni　nanoparticles　Co-Ni/OHPCs)　by　facile　self-crosslinking　assisted　high　internal　phase　emulsion　(HIPE)　templating.　The　oxygen-enriched　porous　carbon　framework　provides　large　specific　surface　area　and　structural　stability,　meanwhile　Co　doping　can　significantly　reinforce　the　electrochemical　performance　of　the　Co-Ni/OHPCs　battery-type　electrodes.　By　optimizing　the　ratio　of　Ni2+　to　Co2+　ions,　the　obtained　Co-Ni/OHPC　electrodes　exhibited　excellent　electrochemical　performance　of　817.3　F　g(-1)　at　a　scan　rate　of　5　mV　s(-1).　Furthermore,　coupling　with　an　activated　porous　carbon　anode,　the　assembled　hybrid　supercapacitor　(HSC)　possessed　an　appreciable　energy　density　of　66.94　Wh　kg(-1)　at　409.9　W　kg(-1)　and　a　capacitance　retention　ratio　of　73.89%　after　5000　cycles,　showing　considerable　application　prospects.　This　structural　design　strategy　provides　new　inspiration　for　the　reasonable　optimization　of　new　electrode　materials　for　promising　hybrid　supercapacitors.　(c)　2022　Elsevier　B.V.　All　rights　reserved.
