Li-based batteries are a hot research topic because they are the most popular energy storage system for high energy-density devices. As an important component of the battery, the current collectors in both cathode and anode should be well designed. Herein, the design of 3D current collectors for Li-based batteries is considered, including 3D metal-based and carbon-based current collectors. The progress in nanotechnology provides appropriate 3D current collectors characterized by highly efficient morphologies and architectures. In particular, 3D current collectors with different morphology are classified. Critical factors of current collectors that affect the electrochemical performance of Li-based batteries are comprehensively debated. Finally, conclusion and perspectives of the future research in this field are discussed.
