"Amorphous phosphatized hybrid interfacial layer for dendrite-free sodi" by Yuanjun Zhang, Zhongyi Huang et al.
Sodium (Na) is a promising anode material for sodium ion batteries due to its high theoretical capacity and favorable redox voltage, but the dendrite growth issue limits its practical application. Herein, an artificial hybrid interface layer based on an amorphous phosphatized hybrid (a-Na3P/NaBr) is developed to facilitate a homogeneous and dendrite-free lateral growth behavior during recurring sodium plating/stripping processes. The proposed Na metal anode delivers an excellent cycling performance for over 200 cycles with an average Coulombic efficiency 99.5% under the capacity of 3 mAh cm−...
