NEWARE Battery Testers: Empowering Battery Material Research and the Advancement of the Battery Industry

Optimizing the Fermi Level of a 3D Current Collector with Ni3S2/Ni3P Heterostructure for Dendrite Free Sodium Metal Batteries

Introduction to academic achievement

Rechargeable Sodium Metal Batteries (RSMBs) have garnered extensive attention as one of the most promising energy storage technologies due to their high energy density and low cost. However, practical applications of metal sodium batteries still face challenges such as the instability of the solid electrolyte interphase (SEI) and the continuous growth of dendrites, which deteriorate the cycling stability of the batteries and give rise to safety concerns, thereby limiting further practical applications.

In light of this, research teams led by Yan Yu and Yao Yu from the University of Science and Technology of China, as well as Meng Gu from Southern University of Science and Technology, theoretically predicted and successfully constructed a Ni₃S₂/Ni₃P heterostructure with a high work function. This structure effectively reduces the Fermi level, thereby suppressing the continuous electrolyte decomposition caused by the electron tunneling effect during long-term sodiation processes. Additionally, the authors successfully introduced the Ni₃S₂/Ni₃P heterostructure onto a three-dimensional porous nickel foam, resulting in the synthesis of Ni₃S₂/Ni₃P@NF material, which serves as an advanced sodium anode current collector. The composite sodium anode (Ni₃S₂/Ni₃P@NF@Na) not only exhibits stable plating/stripping processes for 5000 hours but also demonstrates 2500 cycles with high average coulombic efficiency (99.7%). This work was published in the prestigious journal Advanced Materials, with Huijuan Huang as the first author.
