Descripción del proyecto

Los materiales multicapa podrían superar los problemas con las baterías de estado sólido

Hoy en día, las baterías de iones de litio son omnipresentes. Han cambiado nuestras vidas diarias y la forma en la que funciona el mundo. Estas baterías, desarrolladas inicialmente para la electrónica de consumo portátil, alimentan hoy todo desde productos sanitarios y coches eléctricos a drones y satélites. Las baterías de iones de litio utilizan electrolitos líquidos a través de los cuales fluyen los iones. Las baterías de estado sólido, tal y como sugiere su nombre, utilizan electrolitos sólidos, lo que contribuye a un menor peso, mayor densidad de energía y tiempos de carga más rápidos. Sin embargo, las baterías de estado sólido tienden a degradarse debido a varios procesos químicos. El equipo del proyecto ROCHE, que cuenta con el respaldo de las Acciones Marie Skłodowska-Curie, está desarrollando y optimizando electrolitos de estado sólido mediante la combinación de métodos experimentales y teóricos.

Objetivo

Solid-state batteries can surpass the current Li-ion technology in terms of energy density, battery safety, specific power, as well as fast-charging capability. According to H2020 Work programme, give support to the development of next-generation batteries is a high priority. For that, ROCHE project drives to novel cross-disciplinary approaches empowered by digital technologies that can accelerate research on the next generations of safe and high-performing batteries. In this context, the project presents three main goals: (a) to train the talented young researcher Dr. Manuel Salado, in the design, development and optimisation of solid-state electrolytes (SSEs); (b) to assemble those SSEs in a battery using a multilayer approach, and (c) to understand the role of interfaces in the ionic transport in order to unravel a possible kinetic mechanism in solid-state batteries. The combination of different materials together with theoretical calculations envisage not only improve the cutting-edge technology of solid-state energy storage obtain a fundamental understanding of the layered structures containing ionic conductors and IL-MOF related materials. During his short research career, the fellow has gained expertise in the fabrication of nanostructured materials, acquiring hands-on experience with both structural and optoelectronic characterization techniques. Nonetheless, to further boost his career, the fellow needs to broaden his knowledge in the field of energy-storage at Deakin University (DU), as well as to complement the already known characterization techniques with new ones present at Lusorecursos SA. The training program includes learning the use of in-situ characterization techniques and the introduction to simulation techniques in order to extract a kinetic mechanism in solid-state batteries. This project will also increase his supervision experience, project and intellectual property management expertise, and research funding and proposal writing skills
