Excellenzcluster Post Lithium Storage POLiS

In situ investigation of metal anode ─ solid (polymer) electrolyte interfaces with SIMS and AFM

  • Since 01/2024

    

Lithium-ion batteries play a critical role in the energy transition by temporarily storing electrical energy to facilitate the efficient use of renewable energy sources. They are currently the leading battery option due to their high voltage and energy density. However, the chemicals used in these batteries are not sustainable in the medium and long term. To address this issue, the POLiS Cluster of Excellence is developing new battery materials and technology concepts to achieve efficient and sustainable electrical energy storage. (https://www.postlithiumstorage.org/en/polis) 

We contribute by investigating the interfacial properties and stability of novel post-lithium solid state electrolytes with sodium and magnesium anodes. This includes setting up in-situ deposition experiments tailored to polymeric systems and gaining a comprehensive understanding of the chemical reactions and kinetics occurring at the electrolyte-anode interface.

ORRCABATT

Optimised design for rechargeable and recyclable alkaline MnO2 batteries as flexible energy storage 

  • Since 10/2023
Alkaline batteries are a technology already widely used as primary battery device.
The project aims at developing an optimal design for a rechargeable Zinc Manganese Dioxide battery.
Our work in the project is focused on the analysis of surfaces and interfaces in prototype of batteries or of singular components. The goal is to observe the degradation phenomena that go on, and then to be able to optimize the cell set-up until a performing device is obtained.
For these purposes, we make use of advanced analytical techniques, such as XPS, ToF-SIMS, and FIB-SEM.

MiNaBatt

Micro- to Nanoscale Investigation of Interfacial Processes in Solid-State Batteries with Hybrid Electrolytes to Elucidate the Lithium Transport

  • Since 07/2022

We start the international project MiNaBatt involving the Luxembourg Institute of Science and Technology (LIST) and the group of Dr. F. Richter from the University of Giessen (D). The aim is to investigate the mechanism of lithium-ion conduction through interfaces/interphases in hybrid electrolytes to improve interfacial engineering for future high energy chemical energy storage systems with longer lifetimes and safer performance.
