The past decade has witnessed the boom of porous carbon materials, especially three-dimensional (3D) ones, as supercapacitor electrode materials. Their large surface areas, tunable pore volumes, adjustable degrees of pore interconnectivity, and the potential to possess hierarchical porous networks have enabled them to achieve simultaneously high capacitance and excellent rate capability. This feature is challenging for non-3D counterparts but favorable for supercapacitors. However, behind the prosperity come the problems, and unfortunately, most of the issues are left unacknowledged and unaddressed in the literature available. This perspective aims to identify these problems, discuss the reasons for overlooking, and provide possible solutions to address these issues. The author wishes this article will draw the attention of researchers in electrochemical energy storage to tackle these roadblocks in the future development of 3D porous carbon electrodes in supercapacitors.

过去十年见证了多孔碳材料（尤其是三维（3D）碳）作为超级电容器电极材料的兴起。它们的大表面积，可调节的孔体积，可调节的孔互连度以及具有分层多孔网络的潜力使它们能够同时实现高电容和出色的倍率性能。对于非3D对手而言，此功能具有挑战性，但对超级电容器则有利。然而，繁荣背后是问题所在，不幸的是，大多数问题在现有文献中并未得到承认和解决。此观点旨在识别这些问题，讨论忽略的原因，并提供解决这些问题的可能解决方案。
