A new approach for large-scale fabrication of 2D MoS2 film-based micro-supercapacitors is developed via a simple spray painting of MoS2 nanosheets and subsequent laser patterning of the deposited film. The optimized MoS2-based micro-supercapacitor exhibits excellent electrochemical performance for energy storage, with a high area capacitance of 8 mF cm−2 and excellent cyclic performance, superior to state of the art carbon-based micro-supercapacitors.
