In article number 1802472 , Yet‐Ming Chiang and co‐workers use magnetically aligned Fe 3 O 4 containing oil droplets as pore formers to produce highly oriented, low‐tortuosity pore channels that address transport limitations of thick electrodes (>400 μm thickness) with ultrahigh areal capacity (≈14 mAh cm −2 versus 2–4 mAh cm −2 for conventional Li‐ion). This method opens new opportunities for developing high energy‐density or fast charging low‐cost batteries based on thick electrodes.
