Lithium plating is one of the most damaging ageing mechanisms in Lithium Ion Batteries that also poses a safety risk due to dendrite growth. It is on one side very challenging to detect the onset of lithium plating in operando before the plating even occurs to prevent plating during battery operation as well as very […]

Lithium plating as a more and more important ageing mechanism in modern lithium-ion batteries in the prospect of the growing fast charging demand in electric vehicles is still not fully understood. Especially the impact of the surface electrode interphase (SEI) layer on plating and vice versa is still subject of many questions. Optical measurements have […]

Inkjet printing is a liquid-based additive manufacturing process, in which a slurry is deposited drop by drop onto a substrate. It has proven to be a promising production technology for various applications due to its process-immanent characteristics, such as the high resolution and the multi-material processability. The suitability of the method for processing particle-loaded slurries […]

Introduction The environmental benefits of an electric vehicle face repeated criticism. Along with the use of CO2-intensive, coal-based electricity for vehicle operation, the ecological rucksack of the battery is the primary focus. When the battery is reused at the end of the vehicle’s service life, the environmental benefits far exceed those of just regular recycling. […]

Sionic Energy has taken a complete “system approach” to lithium-ion batteries, creating a full battery technology platform for the next generation of high-performance batteries. The silicon anode/nickel-rich cathode chemistry is widely regarded as the highest energy Li-ion system. Sionic batteries enable the industry’s advanced silicon materials for high-capacity anodes, high-energy nickel-rich cathodes and safe electrolytes, […]

In various applications, Lithium-ion batteries can be exposed to crash events, where they have to withstand severe mechanical loads and deformations. In some cases, such events can remain undetected, for example, when power tool battery packs are dropped, where the plastic case may deform elastically but the cells within the cell undergo permanent plastic deformation, […]

Silicon is considered as the most promising future active material on the anode side of lithium-ion batteries (LIBs), because of its high capacity, high abundance and low costs. However, silicon suffers from two main drawbacks, a large volume change during lithiation [1, 2] and its poor electrical conductivity [3]. In order to address these drawbacks, […]

Silicon is one of the most promising high-energy-density anode materials for upcoming generations of lithium ion batteries. Its high capacity (4200 mAh/g, 9660 mAh/cm^3) is associated with its very high lithium content, which results in drastic volume expansion. Consequently, silicon-based anodes often undergo strong capacity fading induced by cracking, electrolytic side reactions and low ionic […]

Lithium-ion Batteries (LIBs) have reached great importance in many markets and influence our daily life. Due to increase in demand for the batteries with high energy density and flexibility, aspects such as safety, reliability, costs and sustainability get in focus. Replacement of conventional carbonate-based liquid electrolytes towards more environmentally friendly, safe, and sustainable polymer electrolytes […]

The prediction of battery cell voltage is based on either (i) behavior models (i.e., equivalent circuit models) using a set of experimentally predetermined parameters and advantageous short computation times; or (ii) physical models (e.g. finite element method models) requiring long computation times and the knowledge of various physical parameters. In this study, we propose a […]
