However, the growth of Li dendrites during electrochemical deposition, which leads to a low Coulombic efficiency and safety concerns, has long hindered the application of rechargeable Li-metal batteries. Here we show that a 3D current collector with a submicron skeleton and high electroactive surface area can significantly improve the electrochemical deposition behaviour of Li. Li anode is accommodated in the 3D structure without uncontrollable Li dendrites. With the growth of Li dendrites being effectively suppressed, the Li anode in the 3D current collector can run for 600 h without short circuit and exhibits low voltage hysteresis. The exceptional electrochemical performance of the Li-metal anode in the 3D current collector highlights the importance of rational design of current collectors and reveals a new avenue for developing Li anodes with a long lifespan.2015-03-23engjournal articleVoRhttp://hdl.handle.net/2115/72114https://doi.org/10.1038/ncomms76082041-1723Nature Communications618058https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/72114/1/Nature%20Communications6_6608.pdfapplication/pdf2.15 MB2015-03-23https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/72114/3/Nature%20Communications6_6608_suppl.pdfapplication/pdf4.0 MB2015-03-23
