Flexible,　high-performance　miniature　supercapacitors　that　offer　reliable　energy　storage　and　output　are　desirable　for　use　in　portable　and　wearable　electronics.　Herein,　we　developed　micro-supercapacitors　with　three-dimensional　electrodes　by　printing　assembly　of　graphene.　By　controlling　the　microstructures　and　macroscopic　architectures　of　the　graphene　electrodes,　superior　electrochemical　performance　was　achieved;　especially,　we　demonstrated　an　advancement　to　address　the　limitation　of　areal　capacitance.　The　unique　three-dimensional　graphene　structure　also　provides　this　new　class　of　micro-supercapacitors　with　exceptional　mechanical　flexibility.　With　these　remarkable　features,　facile　integration　of　the　micro-supercapacitor　array　into　flexible　printed　circuits　was　demonstrated.　This　printing　assembly　approach　will　pave　the　way　to　explore　energy　storage　systems　with　diverse　structures　and　extended　functionalities.
