En Austria, la Universidad Tecnol\u00f3gica de Graz ha inaugurado una nueva instalaci\u00f3n para el desarrollo de bater\u00edas de estado s\u00f3lido con su socio industrial AVL. Denominada Laboratorio Christian Doppler, la instalaci\u00f3n se ocupa en profundidad de la reducci\u00f3n de las resistencias interfaciales dentro de la bater\u00eda de estado s\u00f3lido.<\/p>\n
Las bater\u00edas de estado s\u00f3lido prometen densidades de energ\u00eda y potencia mucho mayores que las actuales bater\u00edas con electrolito l\u00edquido. Seg\u00fan Daniel Rettenwander, director del nuevo laboratorio, la tecnolog\u00eda a\u00fan no est\u00e1 madura y \"las bater\u00edas de estado s\u00f3lido supondr\u00edan un paso de gigante hacia la e-movilidad en toda la zona\". Uno de los principales retos es la formaci\u00f3n de altas resistencias en las interfaces que impiden el transporte r\u00e1pido de iones entre los electrodos y, por tanto, provocan una p\u00e9rdida significativa de rendimiento.<\/p>\n
\"En la mayor\u00eda de los casos, los culpables son las interfases entre el electrolito en estado s\u00f3lido y el material del electrodo y entre las part\u00edculas del propio electrolito\", afirma Rettenwander, quien y su equipo se est\u00e1n centrando en varios enfoques para resolver el problema: \"La distribuci\u00f3n de la densidad de corriente en las interfases puede homogeneizarse, por ejemplo, introduciendo capas intermedias con propiedades de transporte de litio finamente ajustadas.\" Los investigadores tambi\u00e9n quieren probar m\u00e9todos de carga alternativos y utilizar diferentes m\u00e9todos de carga por impulsos en lugar de corriente continua para lograr una deposici\u00f3n homog\u00e9nea del litio.<\/p>","protected":false},"excerpt":{"rendered":"

Research in this area is centralised at the TU Graz in the new Christian Doppler Laboratory, which is now the twelfth CD laboratory at the Austrian university. What these laboratories have in common is that they are based on research cooperations with commercial enterprises and are financed both publicly and by the participating companies. Drive and testing specialist AVL is on board the CD Laboratory for solid-state batteries. AVL is also on board at the Center for Battery Safety at Graz University of Technology, presented a month ago. The focus here, for example, is on two topics: the defined ageing of batteries to analyse their long-term behaviour and the behaviour of charged batteries under mechanical stress in general and during accidents in particular. Accordingly, the initiators of the centre say that the heart of this facility are the climate chambers for targeted battery ageing and the mechanical test facilities, including a crash facility for charged batteries.<\/p>\n
At the new CD Laboratory just opened to further work on solid-state batteries, AVL emphasises the importance of the new CD Laboratory for its own business: “As a developer of innovative drive batteries, the research findings are extremely valuable for the development of future battery modules based on solid-state battery technology,” says Volker Hennige, Head of the Battery Department at AVL. The joint research is scheduled to last seven years. The budget of the CD Laboratory with its seven employees totals around two million euros. The Federal Ministry for Digitalisation and Business Location (BMDW) is the most important public funding agency.<\/p>\n
Laboratory manager Rettenwander explains that the development of solid-state batteries is already relatively far advanced in contrast to lithium-air batteries or similar experimental battery technologies. “It will still take some time before this type of battery is ready for high-energy applications, such as in electric vehicles, but it is foreseeable even here in Styria as solid-state batteries are already being found in isolated cases as small batteries for electronic components.” The company is familiar with the specific problem areas, is working concertedly on sustainable solutions and sees itself as an important launchpad for the next generation of energy storage systems.<\/p>\n
