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 […]

One of the major customers‘ demands on battery electric vehicles is the lifetime of the battery as a potential cost driver in the future and influencing factor on sales value. Battery aging is influenced by degradation mechanisms, driven by storage and operating conditions, known as calendric and cyclic aging. These mechanisms lead to a loss […]

Sodium-ion batteries (SIBs) are considered a more sustainable, resource saving, and cost-effective alternative to lithium-ion batteries (LIBs) as they can be designed without using critical or scarce raw materials and compounds such as cobalt, copper, lithium or graphite [1,2]. These advantages on the material level, along with the ability of using existing manufacturing equipment, have […]
