To produce battery cells ever more cheaply, the production processes must be optimised continuously. With a throughput of 0.6 to 0.7 GWh/a per electrolyte filling system, the process is a bottleneck in cell assembly and must be highly parallelized to keep up with the throughput of a gigafactory. Additionally, electrolyte filling is decisive for the […]

Unlike lithium-ion batteries (LIBs), where crystalline graphite is commonly used as the negative electrode material, disordered carbons are regarded as more promising for sodium-ion batteries (SIBs). However, further advances towards better reversibility and higher specific capacity are still needed to match or even exceed the properties of graphite in LIBs. The main challenge is the […]

In sustainable mobility, electric powertrains are crucial, with batteries holding utmost importance. Manufacturers compete based on time-to-market for innovative technologies. Battery analytics demand advanced modeling for aging models and a scalable environment for processing data from large vehicle fleets in real-time. This paper focuses on methodologies for enhancing State of Health (SoH) and automatically detecting […]

The rising demand for EVs has led to increased demand for Lithium-ion batteries (LIBs). Due to the limited natural sources of the battery materials, the need for safe and efficient recycling of LIBs is critical. Batteries at their end-of-life still might have residual energy. Therefore, to safely discharge batteries prior to the recycling processes is […]

LiFePO₄ (LFP) cathodes present a promising ‘green’ alternative for lithium-ion batteries (LIBs), providing a reduced environmental footprint due to the absence of cobalt and nickel. With a maximum theoretical capacity of 170 mA h g-1, LFP cathodes have lower energy density than common NMC (LiNixMnyCo1-x-yO2) cathodes but are valued for their high thermal stability, long […]

Over the past three decades, the energy density of lithium-ion batteries (LIB) has steadily increased to meet the growing demand for portable energy storage. This increase in energy density has made LIBs a potential safety hazard. In the worst case, a so-called thermal runaway in the LIB can lead to the destruction of the entire […]

It is widely known that lithium-ion batteries (LIBs) degrade and lose performance during usage. Accurately predicting LIB aging is essential for optimizing design and usage, and enabling second-life applications and recycling. The main causes of LIBs performance decay are mechanical and electrochemical degradations. During battery operation, lithium ions (de)intercalate into the active material particles constituting […]

Multiphysics models have shown potential to support the design of battery systems at beginning of life and control during operation conditions, but still show limitations on the lifetime prediction. Thus, despite significant advances in recent years, the determination and accurate parameterization of descriptive degradation models for battery systems remains an open problem which primarily relies […]

Around four billion discarded tires are in landfills annually, highlighting the need for sustainable recycling methods. One solution is to transform waste tires into carbon powder as active anode material for alkali-ion battery. However, heavy metals and other contaminants in tires reduce the electrochemical performance of the resulting carbon material. Traditional approaches often employ concentrated […]

Batteries have become an omnipresent technology a majority of the population is using every day. The vast majority of these cells are equipped with electrodes composed of current collectors coated with an active material. The current collectors are usually coated on both sides. But applying an asymmectrical lamination of the active material can enhance the […]
