固态电解质膜用于电池Thin Solid Electrolyte Membrane For Batteries
➀ 韩国电子通信研究院（ETRI）的研究人员通过干法工艺开发出了一种超薄固态电解质膜。这种膜比传统固态电解质膜更薄，能够提高能量密度并减小电池体积。
➁ 新型电解质膜通过在机械剪切力下使粘结剂材料纤维化实现，其厚度仅为18微米，远低于目前常用的1毫米厚膜。
➂ ETRI 计划进一步优化离子电导率和电极界面稳定性。使用软包电池的初步测试结果表明，该技术具有商业化潜力。
➀ Researchers from the Electronics and Telecommunications Research Institute (ETRI) have developed a thin solid electrolyte membrane using a dry process. This membrane is significantly thinner than traditional solid electrolyte membranes, enhancing energy density while reducing battery size.
➁ The new membrane is achieved by fibrillating binder materials under mechanical shear force, resulting in a thickness of just 18µm. This compares favorably to the 1 mm thick membranes commonly used today.
➂ ETRI plans to further optimize ion conductivity and electrode interface stability. Preliminary tests using a pouch-type cell show promising results, indicating potential for commercial application.
