In-Situ Annealed Ti3C2Tx MXene Based All-Solid-State Flexible Zn-Ion Hybrid Micro Supercapacitor Array with Enhanced Stability

Flexible Zn-ion hybrid micro-supercapacitors (MSCs) array was fabricated with Ti 3 C 2 T x as the cathode via laser direct writing method, which present ultrastability up to 50,000 cycles after in-situ annealed treatment. A digital timer driven by the obtained single MSC under bending state, together with a flexible LED displayer of the “TiC” logo lighted by the MSC arrays under twisting, crimping and winding conditions demonstrate the great potential application of the MSCs in integrated wearable electronics.
