A new 1,2-dibromobenzene (1,2-DBB) electrolyte additive is developed to accelerate Na ion diffusion through the solid electrolyte interphase layer and induce spherical Na deposition for dendrite-free Na metal anode due to the derived NaBr with high ionic conductivity. As enabled by the 1,2-DBB additive, the Na||Na₃V₂ (PO₄)₃ full cells exhibit excellent long-term cycling performance.

设计用于均匀钠沉积的固体电解质界面：电解质添加剂和优异的高倍率循环稳定性的理论指南

开发了一种新的 1,2-二溴苯 (1,2-DBB) 电解质添加剂，以加速 Na 离子通过固体电解质界面层的扩散，并由于衍生的具有高离子电导率的 NaBr 而诱导无枝晶 Na 金属阳极的球形 Na 沉积. 在 1,2-DBB 添加剂的作用下，Na||Na ₃ V ₂ (PO ₄ ) ₃全电池表现出优异的长期循环性能。
