“Multilayer approach for solid-state batteries” - (ROCHE)
Solid electrolytes represent a significant advancement in battery technology, primarily due to their potential to address the key challenges faced by liquid electrolytes, such as safety risks associated with flammability, leakage, and thermal instability. Additionally, solid electrolytes can improve battery performance by enabling higher energy densities, longer life cycles, and better thermal management. The development of solid-state batteries, which utilize solid electrolytes, is considered one of the most promising approaches to meeting the growing global demand for safe, high-performance, and sustainable energy storage solutions. ROCHE project will use a novel multilayer approach to fabricate solid-state batteries, in which solid inorganic material will be intercalated with MOFs layers. As novelty, three synergetic approaches of metal-organic frameworks (MOF) will be designed to improve and favour the ionic transport. It is expected that the use of the multilayer approach will increase the mechanical resistance compared to an individual one. Also the synergistic effect of the high ionic conductivity and nanowetted interface between the MOF and the cathode will entail a high-capacity and good dendrite suppression capability, allowing its implementation in next-generation solid-state batteries. The combined database and machine learning approach have been applied to design and predict material properties of electrodes such as voltage, crystallinity and chemical stability, from atomic scale to mesoscale.[5] Bearing this in mind, it can been applied to design new SSEs with fast Li-ion transport and mechanical properties. Providing an opportunity for exploring material properties at a lower cost and accelerating the material discovery processes. Once aims have been established, the specific scientific objectives of the project are: (1) The synthesis and optimization of materials with the objective to develop a multi-layer structure of SSEs. (2) The assembly of SSEs in a battery structure and characterize their behaviour under long-test cycling. (3) The understanding of the role of interfaces in the ionic transport in order to unravel a possible kinetic mechanism in solid-state batteries.

Project objective
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
