Sodium/metal chloride storage batteries, used in hybrid propulsion applications, provide high energy and power densities safely and reliably. To understand the dynamics of electrochemical cycling, a high-temperature sodium/ferrous chloride storage cell was modeled in two dimensions. The ... Per saperne di più
Our customer LeydenJar Technologies creates the world’s most energy dense battery anodes, enabling Li-ion batteries that are powerful, small and fast charging. Prime examples of applications include electronic devices and e-mobility. The anodes are made of silicon, and are produced with ... Per saperne di più
The discharge of an alkaline Zn anode involves the conversion of Zn metal to solid ZnO through the zincate ion. With the heterogeneous dissolution of Zn and mobility of zincate in the electrolyte, complex radial distributions of Zn and ZnO have been observed to occur in the anodes of ... Per saperne di più
Lithium ion battery electrodes are porous composite film made up of two or three different types of solid material. Typically using the fabrication of the electrode, the solid powders (active material, binder and in most cases a conductive active) are dispersed in a solvent like NMP and ... Per saperne di più
This case study explains the work we undertook where we modelled an Induction heating system in COMSOL Multiphysics simulation software to correlate the simulation results with actual measurements. The simulated results were cross checked with several different measurement scenarios, ... Per saperne di più
Maritime transport contributes to about 3% of global greenhouse gas emissions. Proton exchange membrane (PEM) fuel cells are considered among the most promising clean technologies for decarbonizing the maritime sector. Some of the main benefits of PEM fuel cells include highly efficient ... Per saperne di più
锂离子电池在便携式电子设备领域占据主导地位，并显著推动了电动汽车的商业化进程。当前全球研发重点集中于开发具有高能量密度、快速充放电能力、高功率输出、低成本及高安全性的电池系统。在材料选择中，机械强度的耐久性与长周期循环的结构完整性成为关键评价指标。锂离子电池内部存在显著的电化学-力学耦合行为，表现为大变形、塑性流动、裂纹扩展与疲劳等现象，进而引起电极剥离、孔隙闭合以及副反应加速等多种失效模式。其中，正极颗粒的破裂等力学-电化学退化机制是限制锂离子电池性能的主要因素之一，因此深入研究正极材料在多场耦合条件下的响应机制，对实现下一代高能量密度电池至关重要。 钴酸锂 ...
