In today’s world, it is unthinkable to travel without our portable electronic devices (PEDs). In fact, it has been shown that every passenger carries 4-5 devices (average) containing lithium ion cells when travelling. Therefore, it is of interest to Airbus to contribute to gaining knowledge about the fire hazards for the industry. The pillars of […]

Mathematical modelling, simulation, optimization, and model-based diagnostics of lithium-ion batteries (LIBs) are broad and growing scientific disciplines. Among many different modelling techniques, equivalent circuit models (ECM) are widely used in practical applications because of their relative simplicity (hence, low computational cost and therefore embeddable), ease of parameterization (because a battery is an electrical system, it […]

Sodium‑ion batteries (SIBs) are emerging as a promising alternative to lithium‑ion batteries (LIBs), driven by the limited and geographically concentrated supply of lithium and other critical metals. Sodium, in contrast, is far more abundant, widely distributed, and less costly to extract, offering a more sustainable and secure basis for large scale energy storage and beyond. […]

The increasing demand for lithium-ion batteries in electric mobility and stationary storage highlights the importance of accurately measuring their physical and electrochemical health. Advanced diagnostic methods are now being used for the early detection of defective cells, from quality control during production to operando monitoring of aging processes. In this study, sensitive magnetic measurement techniques […]

Due to regulatory pressure, fluorine-free alternatives to polyvinylidene fluoride (PVDF) as cathode binders have become potentially important for the industrial production of batteries. However, the majority of research into fluorine-free binders has focused on aqueous processing, which is not a viable short-term alternative for existing gigafactories that rely on the solvent N-methyl-2-pyrrolidone (NMP). Within this […]

Recycling graphite from end-of-life lithium-ion batteries presents challenges beyond economic considerations. Graphite is difficult to separate in high purity from battery waste streams and is therefore rarely targeted as a dedicated recycling product. Conventional purification approaches often involve aggressive leaching or high-temperature treatments, which alter particle surface chemistry and reduce lithium-ion intercalation performance at high […]

“Anode-free” lithium metal batteries are among the most promising next-generation energy storage technologies owing to high specific energy and expected operational safety. Despite significant research progress in recent years, applicable key challenges remain to be solved. Inhomogeneous and irreversible lithium metal deposition as well as consumption of electrolyte components upon cell operation yield continuous interfacial […]

The development of solid-state battery (SSB) technology is driven by the pursuit of safer, more efficient energy storage. SSB cells have several advantages including a lack of liquid electrolyte that can leak and instigate hazardous situations due to its flammability. However, challenges persist including complicated manufacturing, a shorter lifespan due to high electrode-electrolyte interface resistance, […]

In this work, we demonstrate the concept of localized high-concentration electrolytes in PFAS-free LFP || Li cells by directly comparing LiFSI-DME electrolytes (lithium bis(fluorosulfonyl)imide in 1,2-dimethoxy ethane) with two aromatic diluents –- toluene and its fluorinated analogous m-fluorotoluene (mFT). Liquid FT-Raman spectroscopy confirmed the presence of contact ion pairs and aggregates in both LHCE-toluene and […]

The dissolution and diffusion of intermediate lithium polysulfide (PS) species during operation of Li-S batteries can result in active material loss and significant capacity decay. The HPLC-ICP-MS method described in our previous work [1] allows one to quantify polysulfide distributions in organic solvents by a straightforward detection and thus to shed light on the intrinsic […]
