Lithium-Sulfur Batteries are a promising future battery technology due to their characteristics, including high theoretical specific capacities of up to 1670 Ah/kg and gravimetric energy densities of 2600 Wh/kg [1]. These values surpass those of conventional lithium-ion batteries. Moreover, sulfur, a key component in Li-S batteries, is abundant and environmentally benign compared to materials commonly […]

Solid-state batteries (SSBs) hold great promise for revolutionizing energy storage technologies due to their enhanced safety, higher energy density, and potential for diverse applications. However, the realization of SSBs faces significant challenges, particularly in the development of cathode materials that can accommodate high areal capacities while maintaining structural integrity and electrochemical stability. This poster presentation […]

As part of a larger project, we are looking into the effects of temperature on the aging process of large formation commercial batteries. This poster discusses in general some of the findings for batteries cycled at 5°, 25°, and 45° to 80% state of health (SOH). These large pouch cell batteries has around 60,000cm^2 of […]

As complex electrochemical energy storage devices, lithium-ion batteries (LIBs) exhibit coupled multiphysics responses across diverse operational conditions. A well-designed decoupling evaluation offers a more significant opportunity to reveal the interaction and correlation mechanisms between the multiphysics. In the battery packaging design, practical multi-field evaluation of LIBs provides a reasonable solution for thermal management and structural […]

Efficient battery diagnostics and system design present several challenges, requiring models that balance high resolution, fast computation, and physical meaningfulness. However, the effort to acquire measurement data and identify parameters is timeconsuming, and costly. Therefore, a sophisticated electrical equivalent circuit model (ECM) offers the best trade-off between these model descriptions. We developed an automatic global […]

The rising demand and price of lithium in recent years have created an economic opportunity for recovering lithium from pyrometallurgical slags. By using thermodynamic models, lithium can be concentrated in phases like lithium aluminate and eucryptite, which are then separated from gangue material through flotation, followed by leaching for lithium recovery. Flotation efficiency is vital […]

In this study, our objective was to deepen the understanding of the correlation between the microstructure and ionic/electronic conductivity of the composite cathode with the cell performance. For this purpose, a conductive matrix (CM) composed of synthesized Li6PS5Cl with minimal CA content was developed by determining the electronic percolation threshold. The effective ionic and electronic […]

Automated dismantling system for variant-flexible battery recycling Due to the steadily increasing number of end-of-life batteries, efficient recycling strategies are becoming increasingly necessary. In industrial practice, recycling is currently carried out in two stages by dismantling the battery systems and then shredding them. However, due to the current lack of standards, the battery systems have […]

Title: Scanning Acoustic Microscopy-based Battery Analysis Inhomogeneities and other defects have proven to decrease the lifespan of battery cells over time. Currently, there is a lack of detection capabilities of such defects, both during end-of-line inspections and during entrance inspections. This not only has the potential to result in reduced performance when defects go unnoticed […]
