The rapid advancements in emerging portable electronics, transportation, and smart grid-scale energy storage have stimulated the ever-growing demand for high-energy-density, highly safe, and low-cost energy-storage systems. Nevertheless, the continuous large-scale application of lithium-ion batteries (LIBs) is constrained by their soaring cost, considering the shortage and uneven distribution of lithium resources, prompting the replacement of conventional LIBs with new battery systems.
Sodium is the most appealing alternative to lithium as an anode material for cost-effective, high-energy-density energy-storage systems. However, one of the major impediments to the development of sodium-metal batteries is uncontrolled dendrite growth, which penetrates the battery’s separator and results in short-circuiting.
