A New In Situ and Operando Measurement Method to Determine the Electrical Conductivity of the Negative Active Material in Lead-Acid Batteries during Operation Open
The electrical conductivity of the negative active material in lead-acid batteries has been found to significantly influence the properties of the electrode. Though several publications have addressed this subject, essential information on…

Modeling transient processes in lead-acid batteries in the time domain Open
Modeling the performance of electrochemical storage systems divides mostly into two approaches; (extended) impedance bases models, which can model the fast dynamics very good but fail for processes with long time constants, and physical-ch…

Modellierung des transienten Verhaltens von Blei-Säure Batterien:Elektrochemische Impedanz von adsorbierten Spezies Open
Lead-acid batteries are known for more than one century. The fast changing requirements for battery technologies during the last decade have shown that the lead-acid is not well understood. Electrochemical Impedance Spectroscopy (EIS) is a…

Variation of Impedance in Lead-Acid Batteries in the Presence of Acid Stratification Open
Acid stratification is a common issue in lead-acid batteries. The density of the electrolyte rises from the top to the bottom and causes inhomogeneous current distribution over the electrodes. The consequences are unequal aging processes p…

Determination of SoH of Lead-Acid Batteries by Electrochemical Impedance Spectroscopy Open
The aging mechanisms of lead-acid batteries change the electrochemical characteristics. For example, sulfation influences the active surface area, and corrosion increases the resistance. Therefore, it is expected that the state of health (…
