In general battery cells are charged/discharged using constant current or constant power expressed as C-Rates and P-Rates respectively. We are developing a single cell-level Li-Ion battery model in order to simulate the performance and the physicochemical phenomena under power ... Read More
在所有电池系统中，锂氧电池的理论比能量最高，而实际比能量却明显不足。阻碍氧和/或电子传递导致多孔空气电极的有限利用，而实现对电化学和质量传递耦合的定量理解是具有挑战性的。本文首创了一种具有高度一致和可控通道单元的多孔电极，该电极排除了无序孔隙的随机性，从而能够研究控制机制。通过comsol建立了一个动态非均质模型，提供了LiO2的第一个时空分布，揭示了其在有限电子输运下的反向扩散轨迹。实验和模型的协同结合确定了通道尺寸在分为质量，杂交和电子传递控制的机制中的关键作用。对于大孔隙来说，提高Li2O2的导电性和减轻固液界面损伤比增强氧的扩散更为迫切 ... Read More
The COMSOL Application Builder can tie a custom user interface to application-specific Java code. This functionality can be used to automatically coordinate changing model characteristics across multiple model nodes. A simple user interface can therefore allow simultaneous ... Read More
