The proposed dielectric mediums of a hot microbubble interface experience different behaviors due to the electrical mobility of carriers (electron and ion) within their domains. The responses of such mediums towards the initial and average mobility of these carriers can be classified as ... En savoir plus
Introduction The soluble lead flow battery (SLFB) is a form of redox flow battery (RFB), an electrochemical device where energy is stored in a liquid electrolyte. The electrolyte is pumped around a flow circuit from a reservoir to the cell where redox reactions occur and the energy is ... En savoir plus
Lead-acid battery is a reversible battery used generally automotive industry. A lead-acid battery cell contains two electrodes with pasted active material, an electrolyte and a separator. Electrode transmits current with electrons whereas electrolyte transmits current with ions. A grid ... En savoir plus
Electrolyte-gated organic field-effect transistors differ from conventional OFETs by using an electrolyte as the gate insulating material. Due to a high permittivity of the electrolyte, EGOFETs tend to have a higher capacitance than their conventional non-electrolytic counterparts. ... En savoir plus
Model calibration and validation were implemented using experimental data from literature. We utilized a microfluidic electrochemical cell that was configured with parallel, rectangular, and multi-layered channels, which is operating in a co-flow mode. CO2 gas stream enters the cathode ...

We present a detailed 2D COMSOL Multiphysics® model used to determine and improve the conversion efficiency in a liquid-metal microfluidics-based portable energy transducer. To date, most work on power generation technologies has focused on the optimization of existing technologies, and ... En savoir plus
In this work, a mathematical model based on porous electrode theory was developed in COMSOL Multiphysics® simulation software to simulate discharge behavior of primary Zn/MnO2 alkaline batteries. The model integrates microscopic and macroscopic phenomena through incorporation of species ... En savoir plus
Most of steel structures in Japanese harbors are becoming older, the maintenance is one of big problems in our society. As one of anti-corrosion methods for steel structures in seawater, there is a process using electro-deposition of calcareous coating by impression of electric current ... En savoir plus
COMSOL在研究锂金属固态电池负极界面问题的应用 陈翯[1] 沈忠慧[1] [1] 清华大学，北京，中国 锂金属固态电池中，枝晶生长刺穿电解质导致电池短路是电池失效的重要因素之一。研究表明在Poly(vinylidene difluoride) (PVDF)-based固态电解质和锂负极界面会形成稳定非均一纳米界面层，起到高电流密度下自开路作用，从而避免过流引起的安全问题。 通过飞行时间二次离子质谱(TOF-SIMS)，X射线光电子能谱分析（XPS），俄歇电子能谱（AES）确定出PVDF-LiFSI|Li界面层是由Li2CO3，LiF ... En savoir plus
Lithium (Li) metal is an ideal anode material to make high energy density batteries because of its ultrahigh specific theoretical capacity and the lowest reduction potential. Nevertheless, the growth of Li dendrites and uncontrollable side reaction trouble the practical use of Li anodes ... En savoir plus
