With the burgeoning demand for smart portable electronic devices and high-performance electric vehicles, there is tremendous urgency to further dramatically improve energy density of rechargeable batteries. Although utilizing thick electrodes a straightforward productive approach, slow reaction kinetics inadequate mechanical strength caused by thickness increase have hampered their development. Therefore, break through bottleneck electrodes, we comprehensively summarize recent progress electrode architecture engineering in field Considering relationship between structure electrochemical performance, focus on four crucial challenges (high tortuosity, electron ion transport, improper porosity, visible cracking) corresponding solutions (constructing vertically aligned hierarchical channels, introducing multidimensional conductive materials, regulating degree calendering, so on) constructing electrodes. Finally, construction strategy inextricable these factors are summarized, an outlook development research directions toward discussed, providing valuable reference designing
