Entrapment of free lithium in a 3D fibrous Li 7 B 6 framework allows LiB nanostructured anodes with stable interfaces between the electrolyte and the electrode, which retards the formation of lithium dendrites. A lithium–sulfur cell with a nanostructured anode is created with a high Coulombic efficiency and high capacity retention rate of 36.3% after 2000 cycles.
