The ambitious target of the European Union to achieve a climate-neutral European economy by the year 2050 will make electrical energy storages indispensable. To achieve this goal, the demand for lithium-ion battery cells will increase from currently about 700 GWh/a to more than 2.5 TWh/a by 2030. This demand can only be met by the […]

As an excellent choice of energy storage, batteries have been integrated into not only a wide range of industrial applications, but also everyone’s everyday life. At the moment, Li-ion batteries are dominating the market with regard to many applications, as well as in research areas. However, because of the concerns including safety issues, the possible […]

Self-discharge or side reactions on Li-Ion batteries have been extensively investigated in the literature [1,2]. The amount of side reactions depends mainly on the materials utilized and on the test conditions. High temperature and high voltage can increase self-discharge currents [3]. Due to the rise of Na-Ion batteries in the market, more effort is needed […]

In this work, the enrichment of commercially available separators with LiNO3 was investigated in ZELMBs using Cu || Li and NCM622 || Li cell configurations with carbonate-based electrolyte (LP57). The cells with LiNO3-modified separators show superior performance compared to those with unmodified separators. Furthermore, the approach of using LiNO3 precipitated in the separator rather than […]

Prismatic battery cells gain more and more importance especially in automotive applications. With new cell chemistries like lithium iron phosphate (LFP) or sodium ion (SIB), which are enabling larger cell formats and additional trends like Cell2X-architectures without module level, the variety in cell formats increases rapidly. Besides “standardized” VDA formats with classic top terminal design […]

Due to its high specific capacity and availability, sulfur has long been the research focus as a promising cathode active material for high-energy cells. However, intrinsic problems like polysulfide shuttling and sulfur being an electrical insulator have held back its use. An alternative to classical electrodes with sulfur intruded in carbon is an electrode with […]

There is a lack of research summarizing the current literature on the environmental impact related to hydrometallurgical recycling of lithium-ion batteries (LIB) with nickel-manganese-cobalt (NMC) cathodes. Consequently, this work aims to comparatively analyze the current research findings and provide a comprehensive overview about the current state of knowledge. In recent years there has been an […]

Silicon is a promising active material for the anode in lithium-ion batteries (LIB), since it enables much higher energy densities than graphite – the state-of the art material for LIB-anodes. However, the utilization of silicon brings many challenges, which originate mainly from the enormous volume change between the lithiated and delithiated state (300%). One of […]

Summary: Diehl Aerospace GmbH develops and produces emergency power systems and battery packs for aircrafts. Depending on certification requirements, nickel-cadmium- (NiCd), lithium cobalt oxide (LCO) or lithium iron phosphate (LFP) cells are used. They are monitored by an appropriate battery management system (BMS). Besides the functional safety, the determination of the remaining capacity, i.e. State […]

The gelation of the slurry during electrode fabrication is a known issue, especially for the upcoming nickel-rich cathode materials such as LiNi0.8Mn0.1Co0.1O2 (NMC811).[1–3] The gelation originates from the reaction between hydroxides, which form when the NMC comes in contact with moisture, and the polyvinylidene difluoride (PVdF) binder.[4,5] To avoid potential negative effects on the processability […]
