Abstract High energy\u2010density, low\u2010cost batteries are critically important to a variety of applications ranging from portable electronics to electric vehicles (EVs) and grid\u2010scale storage. While tremendous research effort has been focused on new materials or chemistries with high energy\u2010density potential, design innovations such as low\u2010tortuosity thick electrodes are another promising path toward higher energy density and lower cost. Growing demand for fast\u2010charging batteries has also highlighted the need for negative electrodes that can accept high rate charging without metal deposition; low tortuosity can be a benefit in this regard. However, a general and scalable fabrication method for low\u2010tortuosity electrodes is currently lacking. Here an emulsion\u2010based, magnetic\u2010alignment approach to producing thick electrodes (>400 \u00b5m thickness) with ultrahigh areal capacity (up to \u224814 mAh cm \u22122 vs 2\u20134 mAh cm \u22122 for conventional lithium ion) is reported. The process is demonstrated for LiCoO 2 and meso\u2010carbon microbead graphite. The LiCoO 2 cathodes are confirmed to have low tortuosity via DC\u2010depolarization experiments and deliver high areal capacity (>10 mAh cm \u22122 ) in galvanostatic discharge tests at practical C\u2010rates and model EV drive\u2010cycle tests. This simple fabrication method can potentially be applied to many other active materials to enable thick, low\u2010tortuosity electrodes.<\/p>\n","protected":false},"excerpt":{"rendered":"
