This repo is the official implementation of "Deep-Learning-Enabled Crack Detection and Analysis in Commercial Lithium-Ion Battery Cathodes". It currently includes code for the following tasks: In Li-ion batteries, the mechanical degradation initiated by micro cracks is one of the bottlenecks for enhancing the performance.
The classifier, which considers pairs of particles of the post-mortem cell, decides whether they are the result of breakages. In case a particle broke into multiple pieces, every pair of (neighbouring) fragments is detected. To the best of our knowledge, this is the first work of using machine learning for crack detection in lithium-ion batteries.
Herein, we develop a deep learning-based approach to extract the crack patterns from nanoscale hard X-ray holo-tomography data of a commercial 18650-type battery cathodes. We demonstrate efficient and effective quantification of the damage heterogeneity with automation and statistical significance.
In Li-ion batteries, the mechanical degradation initiated by micro cracks is one of the bottlenecks for enhancing the performance. Quantifying the crack formation and evolution in complex composite electrodes can provide important insights into electrochemical behaviors under prolonged and/or aggressive cycling.

Online detection and identification of cathode cracking in Lithium …
Cyclic charging and discharging of Lithium-ion (Li-ion) battery cells lead to the contraction and expansion of the battery electrodes. These contractions and expansions result in the development of internal stresses within the electrodes, further culminating in the growth of cracks. Typically, the cracks in anodes lead to an increase in the surface area hence …

Crack detection in lithium-ion cells using machine learning
In the present paper we used machine learning to detect cracks in the anode of a lithium-ion battery after thermal runaway. The classifier considers pairs of particles and distinguishes three causes for their separation: breakage during the thermal runaway, image segmentation and disjointness in the pristine cell. The decision is mostly based ...
