Abstract

Anode-free batteries promise high energy density but suffer from dendrites, dead sodium, and cathode Na depletion that slow ion diffusion and charge transfer. We introduce the facile chemical pre-sodiation of Cu current collectors to form a Na₁₅Sn₄@Cu coating, which enhances Na affinity, supports uniform nucleation, and suppresses dendrites. Operando XRD confirms improved Na diffusion in NaNi_0.5Mn_0.5O₂, yielding markedly enhanced reversible capacity and cyclability for anode-less sodium-metal batteries.
