Battery technology achieves record high sodium-metal cycling rates

Schematic of a trilayer-based symmetric cell assembly (inset shows an enlarged region of (a) depicting the flow of sodium ions during process of stripping). Stripping and plating mechanisms of sodium metal across the pores of trilayer under an external current is shown in (b) and (c). Credit: Adapted from Energy & Environmental Science (2023).

While lithium-ion batteries currently dominate the industry, serious concern remains about the limited availability of lithium used in these batteries. Conversely, sodium-ion batteries provide a more sustainable alternative due to the tremendous abundance of salt in our oceans, thereby potentially providing a lower-cost …
