Silicon (Si) as an anode active material for lithium-ion batteries (LIBs) has considerably high theoretical specific capacity 3579 mAh/g. However, Si particles expand significantly during charging, making the electrode unsuitable and batteries difficult for long-term cycling1. In LIBs, capacity loss in the first and subsequent cycles is mainly attributed to the formation of a solid […]

A fast and accurate lifetime estimation of a lithium-ion batteries is decisive for planning a sustainable technological future. For this purpose, batteries are aged using the highest possible current rates in accelerated cyclic aging tests excluding test pauses. This strategy, however, can lead to electrolyte-motion-induced salt inhomogeneity (EMSI) [1], which disrupts the homogeneity of lithium […]

The electrification of the transportation sector and the rising deployment of portable devices vehicles have accelerated the development of high-energy-dense batteries and revived interest in lithium metal as a high-capacity anode material alternative to the commonly used graphite. In the presence of well-known organic carbonate-based electrolyte formulations in lithium metal batteries (LMBs), high surface area […]

Lithium metal batteries (LMBs) are attractive for applications requiring high specific energy. There are still some hurdles to overcome on the way to the commercial application of LMBs. The main problems lie in the cycle stability of LMBs and safety concerns. This is due to heterogeneous lithium deposition, which may damage the separator and cause […]

High-energy batteries and their production in energy- and resource-saving processes are required for a successful transition to renewable energies and the associated switch to electric mobility. Solvent-free production of battery electrodes by dry coating eliminates the need for a drying step, offering significant potential to improve both process economics and sustainability. In addition, this method […]

Lithium-ion battery packs have become a dominant technology for automotive and grid energy storage due to their high energy density and relatively low cost. In these applications, a battery pack consists of many individual cells connected in series and parallel to meet the required energy and power demands of the system. Parallel connected battery modules […]

Layered sodium transition metal oxides NaxTMO2 are under ongoing investigation as cathode active materials for sodium ion batteries. Among the wide variety of transition metal compositions, sodium contents and – closely linked – different crystal structures [1]-[3], we focus on NaxFe0.1Mn0.6-yNi0.3-zMy+zO2 (M = Mg or Zn) and investigate the effects of Mg/Zn-doping on the electrochemical […]

Calendar aging plays a crucial role in various lithium-ion battery applications, especially in scenarios where active operation is mostly at low currents or only a few hours a day. Thus, calendar aging is a significant driver of cell degradation during the lifetime (10.3390/en14175220, 10.1109/EMCT.2017.8090361), and may contribute more than cycling to the cell’s aging (10.1016/j.ensm.2023.103147). […]

Loss of lithium inventory (LLI) caused by SEI formation and other degradation mechanisms in Lithium-ion cells is one of the major reasons behind their capacity fade and shorter cycle life. Recent research in academia and industry has explored additives that sacrifice their lithium inventory to compensate for LLI. One such additive for LFP-based battery chemistries […]

A promising path for long-term energy storage is the production of e-fuels via Power-to-X processes (PtX). “Green” hydrogen is generated via water electrolysis and serves as a basic feedstock for the synthesis of chemicals and fuels such as methane, ammonia, methanol and other synthetic hydrocarbons. These fuels offer the advantage of an existing storage infrastructure […]
