Using acoustic emission (AE) measurements enables to indirectly obtain information about degradation processes within a material. By placing a piezoelectric sensor outside a battery test cell, acoustic waves emitted from irreversible process within can be converted into a measurable voltage signal. These processes can be e. g., gas evolution or crack formation. The AE technique […]

Combining nickel-rich layered metal oxide, particularly LiNi0.8Mn0.1Co0.1O2 (NMC811), with a silicon-based anode while simultaneously increasing the upper cutoff voltage (> 4.3 V vs. Li|Li+) represents a significant advancement in lithium-ion battery technology due to its exceptional energy density. However, the current electrolytes’ instability poses a notable challenge for the NMC811||SiOx-Gr application, leading to sudden cell […]

The importance of batteries, fuel cells and electrolyzers is great to meet our future requirements on the energy supply. However, the safety, performance, and lifetime of e. g. a battery will only be as good as the materials that go into making it. Specifically, powder raw materials, electrodes, separators, current collectors, and electrolytes need to […]

The interest in the sustainable use of lithium-ion cells especially in the automotive applications is still very high. In this context, it is particularly important to know the aging behavior of the cells as a function of the operating conditions. In particular, to understand the evolution of solid electrolyte interphase (SEI) in cells operated under […]

The electrical properties of lithium-ion batteries (LIBs) are highly dependent on the production process. Process variations during production lead to a variation of physical product parameters, inhomogeneities, and defects. While defects should be avoided due to their significant impact on the cell’s performance and safety, inhomogeneities are usually acceptable in tolerances [1]. As a result, […]
