Lithium metal is a promising anode for high-energy-density lithium batteries, but its practical application still hindered by intrinsic defects such as infinite volume expansion and uncontrollable dendrite growth. Herein, dendrite-free 3D composite Li ([email protected]) prepared mechanical rolling of lithiophilic LiB nanofibers supported Li–B lithiophobic stainless-steel mesh (SSM).

Lithium-ion batteries (LIBs) are extensively employed in various fields. Nonetheless, LIBs utilizing ethylene carbonate (EC)-based electrolytes incur capacity degradation a wide-temperature range, which is attributable to the slow Li+ transfer kinetics at low temperatures and solvent decomposition during high-rate cycling high temperatures.
