A new sodium–sulfur (Na–S) flow battery utilizing molten sodium metal and flowable sulfur‐based suspension as electrodes is demonstrated and analyzed for the first time. Unlike the conventional flow battery and the high‐temperature Na–S battery, the proposed flow battery system decouples the energy and power thermal management by operating at different temperatures for the storage tank (near room temperature) and the power stack (100–150 °C). The new Na–S flow battery offers several advantages such as easy preparation and integration of the electrode, low energy efficiency loss due to temperature maintenance, great tolerance of the volume change of the metal anode, and efficient utilization of sulfur. The Na–S flow battery has an estimated system cost in the range of $50–100 kWh⁻¹ which is very competitive for grid‐scale energy storage applications.

用于低成本电存储的钠硫液流电池

首次演示并分析了一种新的钠-硫（Na-S）液流电池，该电池使用熔融的钠金属和可流动的硫基悬浮液作为电极。与传统的液流电池和高温Na-S电池不同，拟议的液流电池系统通过在储罐（接近室温）和电池组（100–150°）的不同温度下运行，从而将能量和电源热管理脱钩。 C）。新型Na–S液流电池具有多个优点，例如电极的易于制备和集成，由于保持温度而导致的能量效率损失低，对金属阳极体积变化的耐受性强以及硫的有效利用。Na–S液流电池的系统成本估计为$ 50–100 kWh ^-1 对于电网规模的储能应用而言，这是非常有竞争力的。
