Los investigadores del Centro ExcellBattMat de Dresde del Fraunhofer IWS quieren contribuir con componentes clave al proyecto a gran escala \"C\u00e9lula de bater\u00eda de producci\u00f3n de investigaci\u00f3n\" en M\u00fcnster. El objeto de la investigaci\u00f3n son electrodos fabricados con capas de silicio o litio.<\/p>\n
Antecedentes: Cient\u00edficos alemanes quieren aunar sus conocimientos en varios lugares y desarrollar nuevas bater\u00edas para coches el\u00e9ctricos, entre otras cosas, en el concepto de cubierta de la \"F\u00e1brica de Investigaci\u00f3n de Bater\u00edas\", que puede almacenar al menos un 70% m\u00e1s de energ\u00eda que las soluciones convencionales de iones de litio con el mismo volumen. Estamos hablando de veh\u00edculos el\u00e9ctricos capaces de recorrer hasta 700 kil\u00f3metros con una sola carga de bater\u00eda.<\/p>\n
El objetivo primordial es crear la base para la producci\u00f3n a gran escala de pilas de bater\u00eda en Alemania. Para ello, los cient\u00edficos de Dresde presentan ahora su contribuci\u00f3n a la investigaci\u00f3n de tres a\u00f1os. Desde este mes, trabajan en electrodos formados por capas fin\u00edsimas de Si o Li para conseguir altas densidades de energ\u00eda. Seg\u00fan sus declaraciones, act\u00faan como una forja de alta tecnolog\u00eda para nuevos materiales dentro de la \"F\u00e1brica de Investigaci\u00f3n de Bater\u00edas\", que re\u00fane bajo un mismo techo numerosas actividades de financiaci\u00f3n de bater\u00edas del Ministerio Federal de Educaci\u00f3n e Investigaci\u00f3n.<\/p>","protected":false},"excerpt":{"rendered":"

The Dresden project is entitled KaSiLi (Structural Mechanical Cathode Adaptation for Silicon and Lithium Materials) and is also embedded in the BMBF-funded ExcellBattMat competence cluster for battery materials. According to an accompanying press release, the research team wants to have functional demonstrators ready by 2022. According to an accompanying press release, the new battery design will flow into the battery cell research production project in M\u00fcnster<\/a>.<\/p>\n But what exactly is being researched? The answer: New materials, design principles and processing technologies for the electrodes of battery cells are to be developed in Dresden. Today, the anode in a lithium-ion battery usually consists of a copper conductor a few micrometres thick, covered with a graphite layer about 100 micrometres thick, explains the research team. This graphite layer is to be replaced by much thinner layers of silicone or lithium. In the laboratory, this is already working quite well and is already providing more energy storage capacity. “Today’s lithium-ion batteries have an energy density of around 240-watt hours per kilogram or up to 670-watt hours per litre,” says Stefan Kaskel, professor of chemistry at Dresden Technical University and head of both the ExcellBattMat centre in Dresden and the KaSiLi project. Their aim, specifically, is to achieve “well over 1,000-watt hours per litre.”<\/p>\n Several institutions are involved in the project: The Fraunhofer IWS contributes its experience in thin-film technology. The Fraunhofer IKTS deals with oxide cathode technology and its scaling. The nanoelectronics laboratory NaMLab at the Technical University of Dresden (TUD) uses special spectroscopy equipment to investigate the newly designed anodes. The Dresden Leibniz Institute for Solid State and Materials Research focuses on the structural analysis of electrode layers. The TUD Chairs of Inorganic Chemistry and Inorganic Non-Metallic Materials are responsible for the preliminary research for new electrode structures. Besides, the Dresden facilities cooperate with the three other ExcellBattMat centres in Germany in M\u00fcnster, Munich and Ulm.<\/p>\n
