为满足电动汽车对长续航和快充电的需求，提升锂离子电池的能量密度和快充性能至关重要。锂离子电池在快速充放电过程中的电极结构退化问题已成为制约其性能提升的关键瓶颈。尤其在高倍率循环条件下，电极活性颗粒内部会因锂离子浓度梯度和相变引发的非均匀体积膨胀而产生显著的机械应力，进而导致微裂纹的萌生与扩展。本研究建立了耦合锂离子扩散、相变、应力演化及断裂过程的COMSOL模型，系统研究了单晶电极颗粒、二级电极颗粒和厚电极的断裂行为。在单晶颗粒尺度，建立了耦合锂扩散、相变、应力与断裂的相场模型。研究发现脱锂路径具有取向依赖性，导致非均匀相变与晶格失配应力 ... 詳細を見る
The purpose of this work is to show whether an important difference in Lithium solid concentration and electrolyte concentration can be observed in a Lithium-ion battery model, when considering either the Butler-Volmer kinetics or the Tafel kinetics for describing the electrode kinetics ... 詳細を見る

With the Creation, roll-out, and maintenance of COMSOL Simulation apps, the role of simulation engineers and departments is expanding to include responsibilities similar to those of software developers. Within our department, we have undergone this transformation and will share the key ... 詳細を見る
The adoption of micro- and nanostructured electrodes is a promising technique to improve the performance of Li-ion battery, which increases the electrode surface area and improves the efficiency of ion exchange between the electrode and electrolyte. This performance improvement is ... 詳細を見る
Freeze-dried (lyophilized) drug products offer extended shelf life and improved drug stability within a range of combination products including autoinjectors and pre-filled syringes. A key step in the use of combination products is the reconstitution of the freeze-dried drug product (DP) ... 詳細を見る
A new method is proposed to study battery thermal behavior under nature convection condition, especially focusing on temperature rising and inhomogeneity of battery. Using porous electrode theory, an electrochemical and homogenization heat source thermal coupling model and an ... 詳細を見る
Lithium plating on the graphite anode is a significant factor contributing to the degradation of cell capacity, initiation of internal short circuits, and escalation of thermal runaway in lithium-ion batteries. Non-intrusive detection methods for lithium plating are critical for the safe ... 詳細を見る
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 ... 詳細を見る
As the global use of COMSOL® apps continues to grow, many developers are seeking practical and secure methods to protect their applications and control their usage. While traditional paid software often relies on license keys, there has been a lack of simple and flexible tools tailored ... 詳細を見る
