The need for clean, renewable energy has driven the expansion of renewable energy generators, such as wind and solar. However, to achieve a robust and responsive electrical grid based on such inherently intermittent renewable energy sources, grid-scale energy storage is essential. The unmet need for this critical component has motivated extensive grid-scale battery research, especially exploring chemistries “beyond Li-ion”. Among others, molten sodium (Na) batteries, which date back to the 1960s with Na-S, have seen a strong revival, owing mostly to raw material abundance and the excellent electrochemical properties of Na metal. Recently, many groups have demonstrated important advances in battery chemistries, electrolytes, and interfaces to lower material and operating costs, enhance cyclability, and understand key mechanisms that drive failure in molten Na batteries. For widespread implementation of molten Na batteries, though, further optimization, cost reduction, and mechanistic insight is necessary. In this light, this work provides a brief history of mature molten Na technologies, a comprehensive review of recent progress, and explores possibilities for future advancements.

“…[21]- [23] Most recently, field-assisted sintering techniques such as Spark Plasma Sintering (SPS) have been shown to lower the sintering temperature of SBA to 1300°C while also offering a high degree of control over the orientation of the grains within the polycrystalline ceramic. [24]- [26] Microwave-assisted sintering has also been recently applied to SBA [27], [28]. These techniques all exploit unique combinations of driving forces for sintering (e.g., applied pressure, capillarity) and demonstrate unique advantages, however none of these techniques has been shown effective in achieving any degree of densification below 1100°C.…”

Nanocomposites of sodium alginate (SA) and TiO2 nanoparticles have gained attention in the last decade for their versatile uses in several applications. Indeed, TiO2 is particularly appealing for its photocatalytic and antimicrobial activity and inherent safety. In this paper, TiO2 nanoparticles are successfully embedded, synthesized by a microwave‐assisted method, into SA matrix by a simple solvent casting method to form flexible and self‐consistent SA/TiO2 films. FT‐IR, XRD, and contact angle measurements confirm the formation of homogeneous and hydrophilic bio‐composites films that may be suitable for packaging or life science applications.
