Project description
Amorphous electrolytes and their interfaces hold the key to better lithium batteries
Lithium batteries have great potential for use in energy storage, but further improvements are needed in terms of safety, performance, efficiency, cost and lifetime for their widespread use. Amorphous solid electrolytes are a better alternative to crystalline ones when it comes to their kinetics, but in turn, the former suffer from low fracture resistance that compromises their long-term performance. Funded by the Marie Skłodowska-Curie Actions programme, the TOUGH project aims to elucidate the mechanical behaviour of the interfaces between the amorphous solid electrolytes and the electrodes. The work will focus on optimising the electrolyte and interface structure to achieve high toughness, stable interfaces, and high lithium-ion conductivity.
Objective
Renewable wind and solar energy production and electrification of transport require battery systems to store the electricity until it is needed. Lithium batteries have been very successful, but further improvements are needed in terms of safety, performance, efficiency, cost, and lifetime. The use of solid instead of liquid electrolytes offers a key step forward, but slow kinetics is the Archilles’ heel of solid electrolytes. This problem can be addressed by using amorphous (disordered) instead of crystalline electrolytes, but in turn these suffer from low fracture resistance, compromising long-term performance.
In the proposed project, we will elucidate the mechanical behavior of amorphous solid electrolyte/electrode interfaces. The aim is to optimize the electrolyte composition and structure to simultaneously achieve high toughness, stable interfaces, and high lithium ion conductivity. To this end, we will first understand the structure-conductivity relations in disordered and partially ordered sulfide electrolytes (Task 1). Then the mechanical properties of the individual phases and interfaces will be explored in constructed all solid-state batteries (Task 2). These experiments will be complemented by atomistic simulations to understand the structural changes in the investigated systems during battery operation (Task 3).
The project builds on complementary expertise of the fellow applicant (battery materials) and supervisor (mechanics, amorphous materials). Together with the research and training environment provided by the host organization (Aalborg University, Denmark), this will ensure the achievement of this timely and innovative project as well as the dissemination and exploitation of the expected results. These research outputs will lead to new amorphous materials that can be integrated in future all solid-state batteries. The fellow applicant will emerge from the project with new skills, and the capability to launch his own research group.
