In Situ Integration of Rapid Ion-Diffusion Interlayers on Cu Current Collectors toward Ultrafast Anode-Free Sodium Metal Batteries
Central South University · Powder Metallurgy Institute
Abstract
Anode-free sodium metal batteries (AFSMBs) are acclaimed for their high energy density and low production cost, but they face challenges related to an unstable cycling life due to irreversible Coulombic efficiency and dendrite growth. Although this issue is addressed to some extent by modulating the current collector interface, the effectiveness of these modifications in improving the performance of AFSMBs under extremely high-rate conditions is still insufficient. Here, the Prussian blue analogues (PBAs) as a rapid sodium-ion diffusion interlayer that is integrated in situ on copper current collectors (PBA@Cu) are used to realize high-performance AFSMBs. PBA exhibits a low diffusion energy barrier for sodium…
