Herein, we develop a microsized Bi-Sn alloying particle model system with the engineered eutectic phase boundaries (PBs) that provide high energy density, fast charging capability, and long cyclic stability for sodium ion batteries (SIBs). PBs with spacious atomic misalignment can effectively promote the bulk diffusivity, which facilitates the fast ion diffusion. The asynchronous multi-step alloying mechanism induced by PBs can not only maintain the permanent alloying driving force of particles by releasing stress, but also improve the mechanical robustness and interface stability of particles by changing the process of structure evolution. The Bi6Sn4 anode delivers a fast charging capability of 407 mAh g<sup>−1</sup> at 8 A g<sup>−1</sup> (20C), comparable even to the reported nano-sized alloy anodes.
