A review on the distribution of relaxation times analysis: A powerful tool for process identification of electrochemical systems
Christian Plank,Tom Rüther,Leonard Jahn,Maximilian Schamel,Jan Philipp Schmidt,Francesco Ciucci,Michael A. Danzer +6 more
TL;DR: This review provides a comprehensive overview of Distribution of Relaxation Times (DRT) analysis, a tool for identifying electrochemical processes, including its mathematical basis, data acquisition, and post-processing techniques for enhancing process identification and material characterization.

Model-based lithium deposition detection method using differential voltage analysis
TL;DR: In this paper, a model-based approach distinguishes normal, i.e., after intercalation only, and LD-affected relaxation, and the subsequent voltage behavior during relaxation and discharge is investigated.

Combined dilatometry and voltage analysis for a reliable detection of lithium deposition on graphitic anodes
TL;DR: In this article , the effects of lithium deposition on the cell's voltage and thickness are analyzed in detail, and the dilation behavior of pouch cells during the charge subsequent relaxation phase can be used to detect LD.

Model predictive fast charging control by means of a real-time discrete electrochemical model
Markus Hahn,Lars Grüne,Christian Plank,Felix Katzer,Tom Rüther,Leonard Jahn,Michael A. Danzer +6 more
TL;DR: In this paper, the feasibility of nonlinear model predictive control for fast charging of a graphite electrode is studied. But the authors focus on the simulation and detection of local lithium deposition and do not consider the real-time capability of Li-ion batteries.

Introducing the Loewner Method as a Data-Driven and Regularization-Free Approach for the Distribution of Relaxation Times Analysis of Lithium-Ion Batteries
TL;DR: In this article , the Loewner method was used to identify and analyze the processes of a cylindrical battery and compared with the generalized DRT at two different states of health of the battery.
