Inkjet printing offers capability to produce high‐quality prints sharp details versatile substrate compatibility, making it ideal choice for a wide array applications. Here, preparation range inkjet‐printable 2D material inks is reported fabrication ultra‐flexible machine‐washable textile micro‐supercapacitors. Then heterostructures are proposed enhance performance supercapacitors. This study reveals that unique combination highly conductive graphene insulator hexagonal boron nitride (h‐BN) can areal capacitance graphene‐based supercapacitors by ≈82.48%. The heterostructure‐based also demonstrate higher energy (≈18.06 µWh cm −2 ) densities (≈4333.33 µW excellent retention (≈95% after 1000 cycles). These findings on inkjet‐printed may herald new era future application high‐performance micro‐supercapacitors within wearable technology.
