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.

of lithium metal batteries (LMBs). [3][4][5] Compared with intercalation compounds such as graphite in LIBs, lithium metal anode possesses an extremely high theoretical capacity of 3860 mA h g −1 with a very low redox potential (−3.04 V vs the standard hydrogen electrode), making it an attractive anode material to pair with highenergy conversion cathodes such as sulfur and oxygen. [6,7] Unfortunately, the application of lithium metal is full of challenges that have puzzled researchers for more than 40 years. [8] The most notorious one is that Li metal problematically forms dendrites during repeated cycling. [9] Owing to the multi-component solid electrolyte interphase (SEI) layer and uneven anode substrate, inhomogeneous lithium-ion flux is formed at the electrode/electrolyte interface, leading to nonuniform lithium eletrodeposition on the metal surface. The fresh metallic tip acts as an active site, which induces the ramified growth of lithium dendrite, resulting in cell short-circuit and low coulombic efficiency. This dendrite formation behavior can be much severe at high current densities. Another serious problem lies in electrode volume expansion originated from the repeated plating/ stripping process. [10,11] As a "hostless" electrode, lithium metal tends to be fully stripped when used in practical full cells and can hardly travel back to the same location during plating, causing mechanical instability of electrode/separator interface as well as internal stress fluctuation. As a result, the capacity of LMBs fades sharply during cycling.Over the past four decades, many up-and-coming strategies have been developed to enhance the electrochemical performance of Li metal anode and overcome the problems raised from uneven Li electrodeposition. These methods include doping electrolyte additives (Li halide, [12] ionic liquid, [13] and Cs +[14] ) and coating artificial SEIs (Li 3 PO 4 , [15] Cu 3 N, [16] LiF, [17] and Li alloy [18][19][20] ) on Li anode. More recently, researchers have focused on creating 3D scaffold/lithium metal composites as alternatives for common planar lithium. According to Chazalviel's model, the onset time of uneven deposition is inversely proportional to the current density (τ ≈ -2 J ). [21,22] Therefore, designing high-surface-area composite anode can lower J and thus prolong the cell lifetime. Based on this theory, Cu mesh, [23,24] Ni foam, [25] and other 3D conductive frameworks [26][27][28] have been developed to replace planar current The lithium metal battery (LMB) is among the most sought-after battery chemistries for high-energy storage devices. However, LMBs usually undergo uncontrollable lithium deposition and severe side reactions, which significantly impede their practical applications. Herein, a stable Al 2 O 3 -based inorganic framework with superlithiophilic lithium aluminum oxide (Li-Al-O) interphase is created via reacting Li with Al 2 O 3 nanoparticles. The Al 2 O 3 -based inorganic framework can serve as a stable Li "host," reducing the volume expansion during cell cyclin...

“…[ 10,38,81–83 ] Moreover, the increased surface area also results in the creation of nucleation sites more favorable for Li deposition owing to the higher conductivity of the current collector compared to that of Li metal, thereby suppressing dendrite formation and volume expansion. Currently, 3D current collectors can be fabricated into various forms such as pillars, [ 84,85 ] foams, [ 86–88 ] nanowires, [ 89–91 ] mesh [ 92,93 ] etc. [ 94–96 ]…”

more batteries, this approach fails to exceed the threshold of 500 km in view of the limited battery mounting space in EVs and the almost saturated energy density of state-of-the-art LIBs (Figure 1a).As demonstrated in the road map for the development of the eGolf (an EV from Volkswagen), a driving range of 420 km can be achieved by 2020 based on the currently available LIB chemistry, cell design techniques, and vehicle frame lightening.
