Parameters varied include temperature (T), storage State of Charge (SoC), SoC window and Depth of Discharge (DoD), charge (C c), discharge rate (C d), general current rate (C c/d), charging protocol (CP), pressure (p), and check-up interval (CU). Table 1 Overview of comprehensive battery aging datasets.
The dataset encompasses a broad spectrum of experimental variables, including a wide range of application-related experimental conditions, focusing on temperatures, various average states of charge (SOC), charge/discharge current rates and depths of discharge (DOD), offering a holistic view of battery aging processes.
We present a machine-learning-based battery aging mode detection framework using multiple electrochemical signatures recorded during battery charge-discharge cycles. Through this framework, predominant aging modes, such as loss of Li and loss of active materials in the cathode, can be distinguished at an early stage of life.
For the battery industry, quick determination of the ageing behaviour of lithium-ion batteries is important both for the evaluation of existing designs as well as for R&D on future technologies.
Comprehensive, published datasets on the results of Li-ion battery aging measurements based on optimized experimental designs, which also allow a comparability of the experimental design methodology in terms of their quality of parameter estimation impact, are not yet available.
