The low-temperature electrochemical conversion of CO₂ to ethylene offers significant potential for reducing the chemical industry’s reliance on fossil fuels. Despite recent advancements, the key performance indicators—activity, selectivity, and durability—are insufficient for industrial ... Read More
This work is to present an implementation of COMSOL with MATLAB® [1] for the liquid cooling system of a battery pack based on the physics in COMSOL. The m.file of a model of battery module from COMSOL 4.2 is exported and modified to run in MATLAB®, as well as is managed by using another ... Read More
The reaction current density is an important process parameter of lithium-ion battery, significantly influencing its electrochemical performance. In this study, aimed at the discharge process of lithium-ion power battery, an electrochemical-thermal model was established to analyze the ... Read More
Problem - The occlusion effect is an increase in loudness (sound pressure level) of your internal voice, especially in the low frequency range. Also, self-generated sounds such as chewing, swallowing, walking or running are amplified when the ears are blocked or occluded. Occlusion ... Read More
Solid Oxide Fuel Cells (SOFC) and Li-ion batteries (LIB) are electrochemical devices where performance is dependent on reactions inside porous electrode microstructures. Here we use tomographic techniques to probe 3D electrode structures (anodes and cathodes) at micro-nanometer length ... Read More
为了证明膨胀对电池厚度变化的影响，传统p2d模型耦合移动边界法新建立了一个模型。对复合材料的比例进行了详细分类，以准确分析两种材料对容量的贡献。此外，还研究了电极设计（如活性层厚度和负极孔隙率）以及工作条件对电池电化学性能和厚度变化的影响。当硅含量增加并改变电极结构时，容量贡献率从 85% 增加到 92%。当孔隙率从 40% 增加到 60% 以及负极活性层厚度从 55 μm 增加到 85 μm 时，容量利用率分别从 58% 到 79% 和从 68% 到 59% 不等。在速率测试中，当速率从 0.5 C 变化到 2 C 时，电池厚度变化从 2.49 μm 减小到 1.56 ...
