Abstract：

The　rapid　evolution　of　miniaturized　portable　and　wearable　electronics　has　significantly　intensified　the　demand　for　miniature　energy　storage　devices　featuring　high　energy　density,　cost-effective　fabrication,　and　scalable　manufacturing.　3D　printing　of　energy　storage　electrodes　provides　new　possibilities　for　meeting　these　emerging　needs.　Herein,　we　present　the　development　of　3D-printed　planar　asymmetric　quasi-solid-state　micro-supercapacitors　(MSCs)　with　high　areal　energy　density,　utilizing　cobalt　hexacyanoferrate　(CoHCF)　as　the　positive　electrode　and　activated　carbon　(AC)　as　the　negative　electrode.　The　as-prepared　MSCs　exhibit　a　broad　operating　potential　window　of　1.5　V　and　exceptional　areal　energy　and　power　densities　of　415.8　μWh　cm−2　and　7.5　mW　cm−2,　respectively,　along　with　an　impressive　cycling　retention　rate　of　104.9　%　even　after　15,000　cycles.　Furthermore,　the　printed　MSCs　display　excellent　deformation-tolerant　ability　and　integrability.　These　results　highlight　the　potential　of　CoHCF//AC　asymmetric　MSCs　as　promising　candidates　for　miniature,　flexible,　and　integrable　energy　storage　applications.　©　2025　Elsevier　Ltd
