its low cost, high theoretical specific capacity and low electrochemical potential. However,
Na metal anode has poor reversibility and thereare safety issues of dendritic growth of Na,
which hinder its further application. In this study, we demonstrate that carbon fibre paper
(CFP), as the 3D current collector, suppresses the growth of dendrite and improves the
coulombic efficiency and the voltage hysteresis during long-term cycling due to the good Na …
