摘要
钠金属电池因其高理论比容量和低成本被认为是最具发展前景的大规模储能电池之一。然而，钠金属的高反应活性，易导致固体电解质界面膜不稳定、钠不均匀沉积、枝晶生长等问题。为此，本文采用简单的一步煅烧法制备了一种Al

Abstract
Na metal batteries are considered to be one of the most promising large-scale energy storage batteries due to their high theoretical specific capacity and low cost. However
the high reactivity of sodium metal can easily lead to problems such as instability of the solid electrolyte i
nterface (SEI) film
uneven deposition of sodium
and dendrite growth. Here
an Al

in-situ modified Al foil current collector (Al@Al

) was fabricated by a facile one-step calcination method to promote uniform Na deposition/stripping. During the discharge process
Al

O

is sodiumified to form a Na-Al-O film with high ion conductivity
which not only stabilizes the electrode/electrolyte interface
but also regulates the nucleation behavior on the current collector surface
reducing the formation of nuclear energy barrier
improving ion mass transfer kinetics
and achieving uniform deposition of dendrite-free sodium and long cycle life. The results show that Al@Al

can stably deposit/strip sodium for 50 times with an average Coulombic efficiency of 99.6% under 3 mA·cm
