The　rapid　progress　in　the　development　and　implementation　of　smart　electronics　and　flexible　devices　has　stimulated　the　need　to　produce　energy　storage　units　of　high　efficiency　at　low　cost.　In　this　work,　we　use　laser-induced　graphene　to　construct　in-plane　micro-supercapacitors　(mu　-SCs)　and　delve　into　the　effects　of　inter-finger　spacing,　finger　width,　deformation　state,　and　temperature　on　the　electrochemical　performance　of　the　mu　-SCs　with　five　different　gel　polymer　electrolytes　made　from　H2SO4,　H3PO4,　KOH,　NaOH,　and　NaCl,　respectively.　The　mu　-SCs　with　the　electrolyte　from　the　PVA/H2SO4　gel　polymer　exhibit　the　best　performance　under　bending　and　torsion.　Increasing　temperature　causes　a　slight　increase　of　the　specific　areal　capacitance.　Increasing　the　inter-finger　spacing　reduces　the　specific　areal　capacitance,　and　the　finger　width　has　a　limited　effect　on　the　specific　areal　capacitance.　The　capacitance　retention　of　the　mu　-SCs　with　the　electrolyte　from　the　PVA/H2SO4　gel　polymer　is　94.24　%　of　the　initial　capacitance　after　10,000　electrochemical　cycles　at　a　scan　rate　of　0.1　V/s.　The　specific　areal　capacitance　of　integrated　mu　-SCs　constructed　from　individual　mu　-SCs　with　the　PVA/H2SO4　gel　polymer　is　inversely　proportional　to　the　number　of　mu　-SCs　for　the　series　connection　and　proportional　to　the　number　of　mu　-SCs　for　the　parallel　connection.　This　study　provides　a　feasible　method　to　produce　flexible　mu　-SCs　of　high　efficiency　at　low　cost.
