Abstract :
The cell layouts have a crucial influence on the cooling performance of the battery thermal management system (BTMS). In this work, a novel coupled rotation and wedge-shape cell layout is designed in the air-cooled structures (ACSs). Then the effects of h (height difference of the adjacent cells) and α (rotation angle of the cell) on the heat dissipation performance in the designed ACS are discussed, respectively. Afterward, the single factor and sensitive analysis are implemented to obtain the sensitive range of h and α and identify which one is more sensitive to the thermal performance. Finally, the designed cell layouts are optimized in U-type ACS. Numerical results reveal that the wedge-shape cell layout is more suitable to the U-type ACS. h is more sensitive to Tmax and ΔT of the battery pack than α. In comparison with those of the traditional cell layout, Tmax, ΔT and S after optimization (h = −0.3 mm and α = −6°) are respectively reduced by 5.6%, 19.2% and 67.4%. The proposed cell layout in this work can effectively enhance the cooling performance and provide valuable guidance for the design of air-cooled BTMS. © 2025

Abstract :
Thermal runaway and volume expansion caused by temperature rise under fast charging of lithium-ion batteries (LIBs) are the major reasons of battery explosion and cycle performance degradation. In this work, considering the radiation heat transfer on the battery surface, an electrochemical-thermal-mechanical coupling model of cylindrical LIBs under fast charging (state of charge (SOC) <= 80%) is developed in order to investigate the distributions of the temperature and stress. Then, choosing 18650 LIBs as the object, the charge efficiency, temperature, and stress distributions are compared between fast charging and galvanostatic operation under SOC <= 80%, respectively. Finally, the influences of the thickness, particle radius, the maximum lithium-ion concentration of the cathode, and initial electrolyte concentration on the temperature, radial stress, and hoop stress of LIB during charge are explored, respectively. Numerical results show that fast charging improves 20.8% of the charge efficiency. Increasing the cathodic thickness and decreasing the cathodic maximum lithium-ion concentration or initial electrolyte concentration can reduce the temperature of LIB during the charge. The results of this work will provide some reference value for the design of LIBs under fast charging.

Abstract :
Plenum shape and position play a significant impact on the heat dissipation performance of battery pack with air-cooled structure. However, the existed plenum shape and position are simple. In this work, four different plenum shapes (slanted, convex, concave and stepped) of the battery thermal management system (BTMS) are designed. Then the influences of plenum shapes and positions (at the inlet, outlet, and inlet & outlet) on the heat dissipation performance of the battery are investigated, respectively. Subsequently, a single factor analysis is performed to obtain the range of the design parameters (H-in, H-out, R-in and R-out) in Design 6. Finally, a multi-objective optimization of Design 6 is carried out to further improve the thermal performance of BTMS. Numerical results demonstrate that: 1) For the significant improvement of the cooling ability, convex plenum is at the inlet & outlet whereas other shape ones are all at the inlet. 2) No matter where it is at the inlet, outlet, or inlet & outlet, the convex plenum achieves the excellent cooling effect in Z- and U-type air-cooled structures. 3) Design 6 (convex plenum at the inlet & outlet) exhibits the best cooling ability among all plenum shapes and positions. 4) The design parameters of the optimized Design 6 are H-in = 17.9 mm, H-out = 19 mm, R-in = 2100 mm and R-out = 2000 mm, and the maximum temperature and temperature difference respectively achieve a 35.06 % (18.921 K) and 76.98 % (19.923 K) reduction under such optimized design parameter settings in comparison with those of the benchmark (Design 9).

Objective: Diabetic retinopathy (DR) is a common complication caused by diabetic and can lead to severe visual impairment or even blindness. With the rise of DR population, clinicians demand to adopt an automated diagnosis for reducing some burden. Automated DR classification may improve efficiency and accuracy, and reduce the burden of clinicians. Methods: A full convolution spatial attention module (FCSAM) and CS-ResNet-101 model are proposed for DR classification. In addition, an image enhancement algorithm is proposed to improve the quality of DR images. Furthermore, the cross-entropy loss function is improved to reduce the overfitting. The EyePACS dataset is utilized as training and testing, and the APTOS 2019 dataset is used as external validation. Results: By comparing evaluation metrics of DR classification among different models, the findings are as follows: (1) Accuracy, specificity, sensitivity and F1 score of the CS-ResNet-101 model with the image enhancement algorithm and the improved loss function reach 98.1%, 99.6%, 98.1% and 98.1%, respectively, and it converges faster than other models. (2) The CS-ResNet-101 model exhibits excellent generalization performance on the external validation. Conclusion: The above experimental results indicate that the proposed model with the image enhancement algorithm and the improved loss function is effective and advanced in terms of DR classification. Advances in knowledge: This work proposes an automated DR classification method based on deep learning and an image enhancement algorithm for DR image.

Abstract :
Classic thermoelectric coupling effects, such as the Seebeck effect, Peltier effect, and Thomson effect, highlight the significant impact of temperature on the electrical properties of materials. In contrast to these traditional effects, recent studies have identified the emergence of thermopolarization effects, where temperature gradients induce polarization changes in materials, leading to heat flow. Moreover, temperature gradients can also result in strain gradients within the material, which, unlike the piezoelectric effect, can induce polarization, giving rise to the flexoelectric effect. Despite the growing interest in thermopolarization phenomena, there remains a lack of thorough qualitative and quantitative analysis. In this study, we present a thermo-electro-elastic coupling model for an isotropic hollow cylinder incorporating thermopolarization and flexoelectric effects. This model necessitates modifications to the heat conduction equation, constitutive equation, and governing equation. Through numerical simulations, the impact of thermopolarization coefficient and flexoelectric coefficient on radial displacement, temperature, potential, and electrical displacement is investigated. The results show that the steady-state radial displacement and temperature initially increase and then decrease with variations in the thermal polarization coefficient. Moreover, an increase in the thermal polarization coefficient speeds up the thermo-electro-elastic coupling process towards a steady state. Additionally, mutual interactions between flexoelectric and thermal polarization effects are observed. This comprehensive model provides valuable insights for the design and optimization of microelectronic devices.

Abstract :
Different configurations and proportion of phase change material (PCM) have a vital impact on the thermal performance of the battery thermal management system (BTMS). In this work, the thermal performance of the battery pack is investigated by a combined PCM and air cooling technique. Firstly, four cases of PCM configuration are proposed to investigate the heat dissipation performance. Then PCM proportion is optimized to obtain better temperature uniformity, smaller energy loss and smaller amount of PCM based on Case 4. Finally, subjected to the installation space constraint of battery box (smaller volume), Case 5 is designed to diminish the volume of battery box and the corresponding thermal performance is discussed. The results show that thermal performance with PCM is superior than that without PCM; Case 4 not only enhances the thermal performance but also reduces the amount of PCM; The optimized PCM proportion is only 64 %; Compared with all PCM, the optimized Delta T, Delta P and PCM volume respectively reduce 11.91 % (0.83 K), 11.61 % (4.18 Pa) and 43.06 % (215,544 mm3); Case 5 not only shows more better thermal performance than Case 4 but also reduces 102,200 mm3 (3.48 %) volume of the battery box. The proposed strategy is effective for improving thermal performance of BTMS and saving the amount of PCM.

Abstract :
The electrochemical and mechanical performance of lithium-ion batteries is greatly affected by the porous electrode materials and dislocation effect. A diffusion-mechanical coupling model of porous electrode particle with dislocation effect is developed under potentiostatic operation in this work. Then, the distributions of lithium-ion concentration, volumetric strain and stress in the electrode particles with/without dislocation effect are analyzed. Finally, the influences of porosity and tortuosity on the lithium-ion concentration, volumetric strain, radial stress, hoop stress and strain energy are numerically discussed, respectively. The results show that dislocation effect retards the diffusion and relieves the electrode particle expansion and stresses. Moreover, larger porosity or smaller tortuosity can enhance the charge efficiency and avoid electrode particle damage or crack nucleation and propagation by reducing the stress and strain energy. Finally, from the perspective of fracture, dislocation effect can resist the crack propagation or avoid the formation of cracks during charge. This work will provide some theoretical guidance to improve the charge efficiency and prolong battery life.

Abstract :
Surface effect in the nanoelectrode plays a significant role in the diffusion-induced-stresses which results in fracture at the surface during the charge or discharge of lithium-ion batteries. In this work, considering the surface effect and structural damage, a coupled diffusion-induced deformation model is developed in a nanosphere electrode particle under potentiostatic operation. Then the effects of surface parameters and damage constant on the damage state variable, concentration of lithium-ions, radial stress, hoop stress and equivalent stress are investigated, respectively. Numerical results show that the compressive surface effect reduces the structural damage state variable and the lithium-ion concentration, and hinders the damage through converting the hoop stress from tensile to compressive; The maximum equivalent stress occurs at the surface for smaller damage constant and it will move toward the center for larger damage constant.
