Schematic illustration of direct MXene ink printing. The Ti3C2Tx organic inks, i.e., Ti3C2Tx-ethanol (molecules shown in the bottom panel) are used for inkjet printing of various patterns, such as MSCs, MXene letters, ohmic resistors, etc. The Ti3C2Tx aqueous inks (with water molecules shown in the top panel) are designed for extrusion printing of MSCs and other patterns on flexible substrates. As for the MSCs, a gel electrolyte made of H2SO4-PVA, was coated onto the as-printed patterns and dried naturally, forming all-MXene printed, solid-state MSCs
