Data has become vital in the face of the growing rise of heuristic methods such as machine learning or artificial neural networks and the need to learn about battery life and performance. For this reason, the Electrochemical Safety Research Institute makes data we obtained in the cycle life tests carried out on lithium-ion batteries public so that other research groups can use them to develop new knowledge.
Visit the "Initiative Updates" tab to view data from different experiments.
Data on other energy storage systems will be added as they become available.
Aging and Safety in Cylindrical Cells
Aging due to cycle life refers to all the degradation processes associated with the charge and discharge processes. Every time a Li-ion cell is cycled, its capacity reduces in an imperceptible way. In the long-term cycling, the cell loses a significant amount of its initial capacity.
Aging and Safety in Pouch Cells
Pouch cells do not have protective devices embedded within the cell protecting against overcharge, large currents (external short circuit), and high temperatures like cylindrical cells. Here the behavior of fresh and aged pouch cells and modules under off-nominal conditions is investigated.
