For kinetic analysis a tape-casted electrode was used instead of a 3D printed one (slurry composition 7:2:1 VS2:carbon black:PVDF). Cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) and EIS curves were acquired using a multichannel VMP-3 workstation (Bio-Logic Science Instruments). The PLA cases for the zinc ion battery were fabricated via Fused Deposition Modelling (FDM), using a commercial Ultimaker 2+ printer.
