Latest Patents

Jian Duan holds a patent for an "Ultrasonic non-destructive testing method and system for lithium precipitation in lithium-ion battery." This method involves acquiring full matrix capture data using an ultrasonic phased array transducer. The measured ultrasonic data is then input into an initial fully convolutional network (FCN), which predicts an ultrasonic velocity model. The predicted model serves as the initial input for an acoustic wave equation that outputs reconstructed ultrasonic data. A loss function is constructed using the deviation between the measured and reconstructed data, iterating until convergence. This process trains the unsupervised FCN, which ultimately outputs an accurate reconstructed ultrasonic velocity model representing lithium precipitation in the battery.
