An Overview of Fitting Methods for Electrochemical Impedance Spectroscopy Data
Electrochemical Impedance Spectroscopy (EIS) is a widly used method for the characterization of electrochemical systems. For batteries, EIS measurement results show a strong correlation concerning the State of Charge (SOC), State of Health (SOH), degree of wetting in the production, temperature, and many more characteristics. Assuming that the Kramers-Kronig relation validates the EIS results, thus […]
Ex-Situ Surface Analysis of Electrode-Material with Diffuse Reflectance Spectroscopy
Although decades of research on the aging of lithium-ion batteries (LIBs) has brought fundamental insights and consecutive improvement on LIBs performance, evolution of inhomogeneous effects on the electrode-material and the solid electrolyte interphase (SEI) due to aging is neither completely clarified nor well depicted e.g. in semi-empirical aging models. One major hindrance to reveal inhomogeneity […]
Online power prediction for lithium-ion batteries by integrating electrochemical modeling and machine learning
The knowledge of the dynamic available charging and discharging power of the battery is a piece of essential information for the safety and longevity of the battery energy storage systems. An accurate real-time prediction of these quantities is very challenging due to the high nonlinearities of battery dynamics. In this paper, an electrochemical model-based online […]
A standardized approach towards solid-state battery development
One of the biggest bottlenecks in scaling up new battery technologies, still even today, is the fact that there is no standard way of testing electrochemical performance of battery materials. Unreliable, hard to reproduce results, the typical characterization methods employed nowadays cripple the entire energy storage field and slow down the essential technology transfer from […]

Hybrid Organic/Inorganic Solid-State Electrolyte as Coating Layer for Stabilizing Zinc Metal Anode in Mild Aqueous Electrolyte
Aqueous batteries attract tremendous attention for grid-scale energy storage systems due to low-cost, safety and environmental friendliness. Zinc-ion batteries, in particular, distinguish themselves among the multivalent battery chemistry thanks to the highest theoretical capacity (820 mAh g-1) and cost-effectiveness of the zinc metal anode. However, dendrite growth of metallic Zn caused by uneven deposition in […]

Structural battery composites with solid-state polymer electrolyte produced by slurry coating
With the Flightpath 2050 initiative the European union set the goal to drastically reduce the environmental impact of the air transport sector. Amongst others the CO2 and NOX emissions shall be reduced by 65% respectively 90% until 2050 [1]. A goal that can only be achieved by the development of full electric and hybrid electric […]
Lithium Plating Detection and Characterization Utilizing Impedance Changes During the Lithium Deposition
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 […]
