(Figure ) The designed pore structures form after the templates in the slurry are removed. Bae et al. used co-extrusion to produce templates and thus macro-pore channels, with controlled channel spacings. The resulting low-tortuosity electrodes have tunable channel spacing down to ∼15 μm and showed 3 times areal capacity under 2C charging rate. (88) Sander et al. utilized magnetic field to align the sacrificial templates to create low-tortuous electrodes. The magnetic field can not only align the magnetized nylon rod, but also the magnetic emulsion droplets.(89) Billaud applied a similar method and showed the enhanced ionic transport in the battery.(90) Zhang et al. also combined the magnetic alignment and ice-template method for low-tortuous electrode fabrication. Under 10 mA/cm 2 , the electrodes exhibit an areal capacity of approximately 3.6 mAh/cm 2 . (91) Although physics-guided research has made significant progress, there is still a gap between the optimal structure, particularly in varying application scenarios.
