Quality assurance in battery production In order for a lithium-ion battery to be competitive, it must be manufactured inexpensively, have a high energy density and last as long as possible. When manufacturing battery cells in millions of units, high quality is extremely important; because faulty production can, in extreme cases, lead to self-destruction and a […]

Compositions with transition metal doping at B-site of lithium nickel oxide (LNO) formulae LiNi1−xMxO2 (where M=Zr, Nb and Mo, 0≤x≤0.80) were synthesised via solid state route. Doping is used over past years to enhance the stability of a “stoichiometric LNO composition. This study reveals the impact of doping Zr+4, Nb5+ and Mo6+ impact on the […]

The disassembly process is labour-intensive. Thus, automating this process makes it easier to expand recycling. The different pack architectures – cell to module, cell to pack and cell to chassis/car – force dismantling to be flexible or to focus on one architecture. However, only one type of pack architecture can then be dismantled. Ensuring high […]

The demand for high-energy-density lithium-ion batteries (LIBs) is increasing due to the growing need for portable electronic devices and electric vehicles. Silicon has been identified as a promising anode material due to its high theoretical capacity. But silicon anodes suffer from significant volume changes during cycling, leading to rapid capacity fading and reduced cycle life. […]

Lithium-ion batteries (LIBs) are widely used in various applications due to their high energy density. As electric mobility advances and large quantities of batteries are needed, it is anticipated that a significant stock of end-of-life (EOL) batteries will accumulate within the next decade [1]. The accumulation of this growing stock represents major environmental and economic […]

Today, test data for lithium-ion cells is widely available in public repositories. This article discusses testing conditions of open test data and compares them to the conditions of large-scale BESS in real applications. Coupling the information provided by these datasets and measurements from stationary storage connected to the grid, a data-based model to predict the […]

Hochspannungsbatterien bestehen aus einem Netzwerk einzelner Batteriezellen, bei dem die Anzahl in Serie geschalteter Zellen sehr groß im Vergleich zur Anzahl parallel geschalteter Zellen ist (s>>p). Das Verständnis und die Beherrschung des Kurzschlussverhaltens solcher Systeme ist von entscheidender Bedeutung für das Design sicherer und effizienter Hochvolt-Batteriepack-Systeme. Anwendungen, bei denen Betriebsspannungen von mehr als 1500V angestrebt […]

This study investigates the development of tailored electrolyte formulations for commercial sodium-ion batteries (NIBs) with layered oxide cathodes and hard carbon anodes. The electrolyte plays a central role in improving key performance indicators (KPIs). By adjusting the electrolyte, material degradation and sodium plating are to be minimized while ensuring compatibility with existing patents. The aim […]

Stress and strain inhomogeneities in cylindrical lithium-ion battery cells caused by formation and cyclic aging induced swelling have been investigated by a vast number of researchers and have been identified as a cause for inhomogeneous and significantly accelerated battery aging. Among those, one only recently described mechanism is Electrolyte motion induced salt inhomogeneity (EMSI), which […]
