Designing a Setup to Study the Influence of Pressure on Solid-State Battery Materials at Electrode Level
This research aims to explain the influence of external pressure on solid-state battery (SSB) materials specifically at the electrode interface. In contrast to traditional liquid electrolyte batteries, SSBs necessitate elevated pressure levels to ensure effective contact between the electrode layers and the solid electrolyte. To facilitate this investigation, an experimental framework was established to assess […]
Stable and thin solid electrolyte layers for high-energy solid-state batteries
All-solid-state batteries (ASSB) show great promise for the advancement of high-energy bat-teries as can be seen in recent prototype demonstrations of Toyota, Nio and Mercedes. To maximize the energy density, a key research interest lies in the development of ultrathin and highly conductive solid electrolyte (SE) layers. Additionally, scalable processing of SE layers is desirable […]
Machine learning-based lifelong estimation of lithium plating potential: A path to health-aware fastest battery charging
Enabling Fast and Long-Life Charging for Lithium-Ion Batteries The transition to renewable and sustainable transport demands batteries that support both fast charging and extended lifetimes—two objectives that often conflict. Our study introduces a novel approach to overcome this trade-off by actively monitoring and controlling the anode’s lithium plating potential in real-time. Experiments on three-electrode cells […]
On the challenge of developing scalable and sustainable Aluminum-Ion batteries: From Active to Passive Materials
The ongoing energy revolution has spurred interest in new battery types with innovative cell chemistries over the last five to ten years. This shift is partially driven by the increasing gap between the demand and supply of essential resources like lithium, nickel, and cobalt, resulting in volatile prices, particularly for lithium.1, 2 Consequently, the search […]
Individual cell temperature online monitoring with low installation effort and high robustness
For comprehensive monitoring of the battery cell status and early detection of potential thermal runaway issues it is desirable to have real time monitoring of the temperature of each single battery cell. So far, this has not been practical in commercial use due to high cost and high installation effort in temperature sensor integration. Also, […]
SisClever process: simultaneous recovery of metals from electronic waste to high purity and high concentration via solvent extraction
Sustainability requires the systematic recycling of materials. The challenge is that waste is usually a mixture of many components. As a result, the treatment of waste streams requires complex and costly processes. At the same time, valuable components that are present in low concentrations in the waste stream are difficult to be economically recycled. Examples […]
How the main aging mechanism in 1st life usage influences the safety in 2nd life applications
Li-ion batteries degrade during their usage (cyclic aging) and during storage (calendar aging). The reasons for degradation on the cell level are aging mechanisms on the material and electrode level which are accessible by Post-Mortem analysis. However, even after extensive usage of batteries and a reduction of the capacity to 70-80 % of the initial […]
