Carbon Nanotubes (CNTs) have been hailed as beneficial conductive additive material in Silicon-based anodes due to their unique features such as high electronic conductivity and the ability to mitigate the volume expansion of lithiated Silicon anode-based battery cells. However, both CNTs and Silicon irreversibly consume an enormous amount of Li-Ion inventory to form the SEI-layer, […]

The thermal runaway of individual lithium-ion cells is a complex process that depends on a multitude of factors [1]. Among these factors, state of charge (SOC) plays a crucial role as it influences the initial temperature and energy released during a thermal runaway and therefore its severity [2]. If a cell enters thermal runaway, the […]

In battery cell production, electrolyte filling is one of the most time-consuming steps, thus limiting the overall throughput of cells being manufactured. Since electrolyte filling takes place in an opaque cell enclosure, analysis of the processes and corresponding mechanisms requires hugh experimental effort. As a result, the cause-effect relationships are poorly understood. Thus, simulative observation […]

The development of highly efficient recycling processes for lithium-ion batteries (LIBs) is crucial for future sustainability of this technology, as state-of-the-art LIBs rely on critical raw materials such as graphite, lithium, nickel, and cobalt. Instrumental analytical techniques are valuable tools to elucidate chemical processes during recycling to improve the process. In contrast to conventional recycling […]

We demonstrated Potassium hexachlorostannate, K2SnCl6 (KSC) as a new electrode material for non-aqueous chloride-ion batteries. K2SnCl6 microstructures are synthesized through the one-pot mechanochemical ball-billing route, which is an effective way in comparison to high-temperature sintering techniques and organic solvent-assisted processes. The electrochemical performance of anti-fluorite structured K2SnCl6 has been investigated in non-aqueous electrolytes with lithium […]

As a key component of electric vehicles (EVs), batteries are pivotal for decarbonising transportation and combating climate change. However, increasing competitive pressures in the battery ecosystem, driven by the race for next-generation batteries (NGBs) to address the limitations of current lithium-ion batteries (LIBs), highlight the importance of strategic decision-making. Leveraging data analytics for objective insights […]

Utilizing laser technology to modify the architecture of electrodes within lithium-ion batteries holds significant promise for enhancing battery performance, particularly in achieving stable and high-power outputs while maintaining elevated electrode loading [1]. By selectively ablating sections of the electrode, additional space is created for electrolyte infiltration, thereby enhancing its penetration throughout the electrode’s thickness and […]

In the future, large quantities of end-of-life lithium-ion batteries will be sent for recycling. Current mechanical recycling processes focus on the recovering of the “black mass”, which often results in material losses, especially for aluminum. In response, mechanical processing techniques like zig zag air separator, Fe-separator, impact mill and density table, as well as X-ray […]

Secondary batteries, particularly Lithium-ion batteries have become ubiquitous as power sources for portable electronic devices, electric vehicles, and renewable energy storage systems to name a few. Despite this success, performance limitations, environmental concerns and geo-politics drive innovation towards further improved and/or alternative battery designs and constructs. Atomic layer deposition (ALD) is a proven and powerful […]

The filling of the electrolyte and the subsequent wetting of the electrodes is a quality critical and time-intensive process in manufacturing of lithium-ion batteries. Currently, the process times and process framework conditions for wetting are defined empirically with high safety margins. This leads to long battery cell storage times with high added value. Due to […]
