锂离子电池电极将受益于目前的结构重新设计研究，以实现更厚的电极。增加电池电极的厚度可以显著提高重量能量密度，同时降低制造成本。如果要在商业上充分实现向可持续运输系统的过渡，这两个指标都至关重要。然而，阻碍这种微结构使用的重大障碍仍然存在：性能问题、制造挑战和可伸缩性都仍然是开放的研究领域。从这个角度出发，我们讨论了适应当前厚电极制造工艺的挑战，以及孔工程为设计更厚、更好的电极同时考虑长期性能和可扩展性所带来的机遇。
Lithium-ion battery electrodes are on course to benefit from current research in structure re-engineering to allow for the implementation of thicker electrodes. Increasing the thickness of a battery electrode enables significant improvements in gravimetric energy density while simultaneously reducing manufacturing costs. Both metrics are critical if the transition to sustainable transport systems is to be fully realized commercially. However, significant barriers exist that prevent the use of such microstructures: performance issues, manufacturing challenges, and scalability all remain open areas of research. In this Perspective, we discuss the challenges in adapting current manufacturing processes for thick electrodes and the opportunities that pore engineering presents in order to design thicker and better electrodes while simultaneously considering long-term performance and scalability.
