Stratified Interphase Design for Stable Sodium Batteries.

Stratified Interphase Design for Stable Sodium Batteries. This illustration demonstrates the stratified interphase in zero-sodium-excess batteries, featuring a sodiophilic magnesium (Mg) bottom layer and a sodiophobic sodium fluoride (NaF) top layer. The dual-layer structure facilitates uniform sodium ion deposition, blocks electrons, and prevents dendrite growth, significantly enhancing battery performance and stability.
