As　miniaturized　energy　storage　devices,　flexible　planar　microsupercapacitors　(MSCs)　with　high　performance　have　broad　applications　on　flexible　electronics.　However,　traditional　electrode　fabrication　methods　(photolithography,　laser　writing,　inkjet　printing,　etc.)　are　complex　and　expensive.　In　this　work,　a　patterned　interdigital　electrode,　which　was　prepared　with　a　hard　template　of　hydrophobic　glue　paper,　was　proposed.　Peelable　nickel　nanocone　arrays　(NNAs)　and　polypyrrole　nanotubes　(PPyNTs)　were　electrochemically　deposited　on　the　substrate　as　3D　conductive　frames　and　active　material,　respectively.　The　device　demonstrates　an　areal　capacitance　up　to　60.2　mF　cm-2,　high　capacitance　retention　of　84.3%　after　5000　cycles,　as　well　as　impressive　mechanical　performance　that　can　work　after　180°　bending.　Furthermore,　a　high　energy　density　of　5.35　μWh　cm-2　and　power　density　of　2　mW　cm-2　were　obtained.　Lastly,　the　fabricated　MSCs　presented　great　potential　to　integrate　with　series　and　parallel.　©　2021　American　Chemical　Society.　All　rights　reserved.
