随着航空航天,通信和能源存储系统中高功率电子设备的快速发展,巨大的热量频率对电子设备安全构成了越来越多的威胁。与几个微厚度的薄膜相比,高质量的石墨烯厚纤维(GTF)超过数百微米厚度是一个有希望的候选者,可以解决由于较高的热量量,以解决热管理挑战。然而,传统的GTF通常具有较低的导热率和弱的机械性能,归因于板板比对和脆弱的界面粘附。在这里,提出了一种无缝的键合组件(SBA)策略,以使GTF超过数百微米,具有可靠的合并界面。对于厚度为≈250μm的GTF-SBA,平面内和平面导热率分别为925.75和7.03 w m-1 K-1,大约是传统粘合剂组装方法制备的GTF的GTF的两次和12次。此外,GTF-SBA即使在77 k循环到573 K的严酷温度冲击后,也表现出了显着的稳定性,从而确保了其在极端条件下长期服务的环境适应性。这些发现提供了对石墨烯大块材料界面设计的宝贵见解,并突出了高性能石墨烯材料在极端热管理需求中的潜在应用。

Nordhausen / supraregional。EAS Batteries、IoLiTec Ionic Liquids Technologies 和布伦瑞克工业大学的三所研究所联手开发了可持续且经济高效的钠离子电池生产工艺。钠离子技术旨在补充未来的锂离子技术,以经济和生态合理的方式满足日益增长的储能需求。“NaNaBatt”研究项目由联邦教育和研究部资助计划“未来电动汽车、固定式和其他行业相关应用的电池材料 - 电池 2020 转移”(资助代码 03XP0569)资助约 160 万欧元。总金额为 220 万欧元。EAS Batteries 负责协调该研究项目。电池技术:钠离子与锂离子的比较钠离子电池被视为未来有吸引力的存储技术。与关键原材料锂相比,钠的储量十分丰富,而且可以以更环保的方式提取。钠离子电池对环境的实际影响在于其制造过程,例如通过电力和加热需求。这就是“NaNaBatt”项目的用武之地,该项目优化了钠离子电池的生产过程,以创建一种可持续的存储技术,其性能与锂离子电池相当。尽管钠离子电池的相对能量密度低于锂离子电池,但这可以通过大约高出 20% 的电池体积来弥补。未来,钠离子电池将适合用作固定式储能系统和移动应用。它们比锂离子电池具有安全优势,预计未来使用寿命更长,这将大大降低其总体成本。工艺转移:可持续、创新和成本效益高“NaNaBatt”研究项目的目标是在早期阶段将锂离子电池生产中已建立的高效工艺(尤其是其电极)转移到钠离子技术。这种方法将使环保型可充电电池更快地进入市场。所使用的活性材料充足、易于采购且易于回收。结果将以大型圆柱形电池的形式展示,在经过一千次充电和放电循环后,其所谓的“健康状态”应至少达到百分之九十。然后,将在环境绩效评估中分析为创新和环保工艺策略开发的加工技术。该研究项目将持续三年,于 2026 年 10 月 31 日结束。研究结果将确保德国电池生产长期进一步发展。新专业知识将加强德国作为工业基地的地位,开发的产品将开拓新市场。这将创造技术性工作和国际竞争力。字符:3243(包括空格)
