Additive Manufactured Custom Architectures: LFP, LTO, and ILE gel solutions were digitally patterned using a custom-built direct ink write (DIW) printer. Solutions were placed into10 mL syringes and extruded through 250 µm nozzles to print thin films on planar and non-planer surfaces. The volumetric rate of material extrusion was 0.375 uL s -1 , 0.540 uL s -1 , and 0.589 uL s -1 for LFP, LTO and ionogel, respectively and the printing speed was fixed at 10 mm s -1 . A constant nozzle offset of 150 µm from the surface of the substrate was maintained during deposition. LFP and LTO films were printed on aluminum foil by rastering the nozzle's toolpath such that continuous rectangular films were produced. Prior to placing ILE gels in syringe, the solution was aged at 80 °C for 3 hours on a hot plate to partially polymerize the solution and slightly increase its viscosity. This step promoted printed films shape retention as required for subsequent handling. A supplementary video of the ILE gel printing process can be found in Supplementary Video 1. These aged ILE gels were printed directly onto LFP and LTO films and punched prior to full gel polymerization to prevent cracking.
