El Centro Aeroespacial Alem\u00e1n (DLR) y el instituto noruego SINTEF investigan bater\u00edas de iones de litio sin cobalto en el proyecto HYDRA de la UE junto con diez socios. Quieren probar un prototipo listo para la industria que funcione en el mundo real en un sistema de bater\u00edas para barcos.<\/p>\n
Aunque los socios eligieron una bater\u00eda de barco como demostrador, los conocimientos adquiridos en el proyecto del Instituto SINTEF noruego deber\u00edan ser transferibles a otros veh\u00edculos el\u00e9ctricos de bater\u00eda, es decir, coches, camiones y autobuses. Un total de doce instituciones de investigaci\u00f3n participan en HYDRA, procedentes de Italia, Francia, Suecia, Noruega, Alemania, Ruman\u00eda, Reino Unido y B\u00e9lgica.<\/p>\n
Se centran en la sostenibilidad: Los electrodos de las nuevas c\u00e9lulas no contendr\u00e1n cobalto y contendr\u00e1n un 85% menos de materias primas perjudiciales para el medio ambiente. As\u00ed, seg\u00fan el DLR, las c\u00e9lulas se basan en cambio en materiales \"no problem\u00e1ticos\" como el hierro, el manganeso y el silicio. Sin embargo, al menos la extracci\u00f3n de manganeso de las profundidades marinas es controvertida.<\/p>\n
El Instituto de Termodin\u00e1mica T\u00e9cnica del DLR analiza los procesos electroqu\u00edmicos del interior de las novedosas pilas y comprueba su rendimiento y estabilidad a largo plazo. Para ello, las pilas se cargan y descargan repetidamente en diferentes condiciones de funcionamiento cotidianas. De este modo se garantiza que los procesos electroqu\u00edmicos en el interior de las pilas sean representativos del uso pr\u00e1ctico.<\/p>","protected":false},"excerpt":{"rendered":"

“We measure how the electrical power and storage capacity change after many hundreds of charging and discharging cycles, for example, when the power demand is high, during particularly fast charging processes, and at different temperatures,” explains Dennis Kopljar, head of the DLR’s part in the HYDRA project. “At the end, we open the battery cells and look at how the structure and composition of the materials have changed during operation.”<\/p>\n
SINTEF uses this data from the DLR tests to simulate the chemical and physical processes in the battery. These findings are, in turn, used to adjust the electrode materials and cell design gradually. According to Kopljar, this will provide information that “designers can use to design battery systems and their operating modes to suit the application in question.”<\/p>\n
In addition to eliminating cobalt and other critical materials, the novel electrodes are also expected to excel in sustainable and cost-efficient production. To this end, a water-based process without organic solvents is being developed as part of HYDRA.<\/p>\n
The HYDRA project is funded by the EU with more than nine million euros and is scheduled to run until the end of August 2024.<\/p>\n
