Miniaturized aqueous zinc ion batteries are engaging power storage gadgets for wearable electronics, owing to their security and low price. Layered vanadium disulfide (VS2) has demonstrated aggressive cost storage functionality for aqueous zinc ion batteries, on account of its multivalent states and enormous interlayer spacing. Nonetheless, VS2 electrodes are affected by fast oxide conversion, they usually current predefined geometries and side ratios, which hinders their integration in wearables gadgets. Right here, we exhibit the formulation of an acceptable ink for extrusion-based 3D Printing (Direct Ink Writing) primarily based on micro flowers of layered VS2 obtained utilizing a scalable hydrothermal course of. The 3D printed architectures of arbitrary design current electrochemically lively, porous and micron-sized struts of tuneable mass loading. These have been used as cathodes for aqueous zinc-ion batteries electrodes. The 3D printed VS2 cathodes have been assembled with Carbon/Zinc foil anodes to kind full cells of zinc-ion, demonstrating a capability of ~ 1.98 mAh cm-2 with an working voltage of 1.5 V. Upon biking a capability retention of round 80% was achieved after ~100 cycles. The selection of the electrolyte (a water-in-salt electrolyte) and the design of the pre-processing of the 3D printed cathode ensured improved stability towards dissolution and swift oxidation, infamous challenges for VS2 in aqueous atmosphere. This works paves the way in which in the direction of programmable manufacturing of miniaturized aqueous batteries and the supplies processing strategy will be utilized to totally different supplies and battery methods to enhance stability.
