In this study, a detailed review of different strategies that has been used to optimize and enhance different BTMSs has been conducted using a combination of the conventional and bibliometric approaches. Based on the analysis of the literature, it was found that several researchers in recent times have conducted studies that investigated creative design approaches, computational methods, optimal cooling, and structural improvements to improve battery performance, safety, and service life. Among the methods and materials employed in the various studies are genetic algorithms, mini-channels, composite phase change materials, orthogonal testing, nanofluids, and surrogate modeling. The study also discovered that while air-cooled BTMS provides simplicity, safety, and consistency, its use is restricted to low-capacity batteries due to its lower heat capacity. Although it needs a sealing cover to stop leaks, liquid-cooled BTMS was found to be promising. Additionally, liquid metals and nanofluids are also being explored due to their increased heat conductivity. The study also identified the limitations associated with the various cooling mechanisms.

To ensure the safety of these batteries during operation, this paper presents a battery defect detection method based on ultrasonic guided waves and a Convolutional Long Short-Term Memory (ConvLSTM) neural network model. By utilizing lead zirconate titanate (PZT) ultrasonic transducers to excite ultrasonic guided waves within the battery and employing a laser Doppler vibrometer (LDV) to receive ultrasonic signals from the battery surface, the entire propagation process of the ultrasonic guided waves within the object is captured. To enhance the robustness of the model, data augmentation techniques are applied. By augmenting the data from pouch battery test samples, the number of effective images for model training was increased from 3400 to 15,300. To learn from the dataset of defective batteries and prevent gradient explosion during training, this paper proposes an algorithm inspired by the U-Net model, which incorporates spatiotemporal information. The algorithm introduces a ConvLSTM module, enabling the model to learn and retain temporal features from time-series images, and to segment and identify internal battery defects based on the propagation characteristics of ultrasonic guided waves. Experimental comparisons demonstrate that the proposed method excels in identifying internal defects in batteries, with an intersection over union (IoU) of 80.32 % and a pixel accuracy (PA) of 96.47 %.
