Researchers develop a process that can lead to mass synthesis yields solid sulfide electrolyte with world's highest reported sodium ion conductivity and glass electrolyte with high formability.
研究人员开发出一种工艺，可大规模合成具有全球最高报道钠离子导电率的固体硫化物电解质，以及高成型性的玻璃电解质。

The pursuit of greener energy also requires efficient rechargeable batteries to store that energy. While lithium-ion batteries are currently the most widely used, all-solid-state sodium batteries are attracting attention as sodium is far more plentiful than lithium. This should make sodium batteries less expensive, and solid-state batteries are thought to be safer, but processing issues mean mass production has been difficult.
对更绿色能源的追求还需要高效的可充电电池来储存能源。虽然锂离子电池目前应用最广泛，但全固态钠电池正受到关注，因为钠的储量比锂丰富得多。这应会使钠电池更便宜，且固态电池被认为更安全，但加工问题意味着大规模生产一直很困难。

Osaka Metropolitan University Associate Professor Atsushi Sakuda and Professor Akitoshi Hayashi, both of the Graduate School of Engineering, led a research team in developing a process that can lead to mass synthesis for sodium-containing sulfides.
大阪都市大学工程研究生院的副教授Atsushi Sakuda和教授Akitoshi Hayashi领导的研究团队开发了一种可实现含钠硫化物大规模合成的工艺。

Using sodium polysulfides (sulfides with two or more atoms of sulfur) as both the material and the flux, which promotes fusion, the team created a solid sulfide electrolyte with the world's highest reported sodium ion conductivity -- about 10 times higher than required for practical use -- and a glass electrolyte with high reduction resistance.
该团队使用多硫化钠（含两个或更多硫原子的硫化物）作为材料和助熔剂（促进融合），制备出一种固态硫化物电解质，其钠离子电导率达到全球已报道的最高值——约为实际应用所需值的10倍，同时还开发出具有高抗还原性的玻璃电解质。

Mass synthesis of such electrolytes with high conductivity and formability is key to the practical use of all-solid-state sodium batteries.
大规模合成具有高导电性和可成型性的此类电解质是全固态钠电池实际应用的关键。

"This newly developed process is useful for the production of almost all sodium-containing sulfide materials, including solid electrolytes and electrode active materials," Professor Sakuda said. "Also, compared to conventional methods, this process makes it easier to obtain materials that display higher performance, so we believe it will become a mainstream process for the future development of materials for all-solid-state sodium batteries."
"这种新开发的工艺几乎适用于所有含钠硫化物材料的生产，包括固体电解质和电极活性材料，"Sakuda教授表示。"与传统方法相比，该工艺更容易获得性能更优异的材料，因此我们相信它将成为未来全固态钠电池材料开发的主流工艺。"
