Key points of lithium ion battery production process control – Semco university

Leave a Comment / Pack Assembly / By

Introduction: Lithium Ion Battery Production Process in sets of electrodes and then assembled in cells. Active material is mixed with polymer binders, conductive additive, and solvents to form a slurry that is then coated on a current collector foil and dried to remove the solvent and create a porous electrode coating. There is no single lithium-ion …

How the three electrode system works – Semco University

8 Comments / General / By

Introduction The three electrode system consists of a working electrode, counter electrode, and reference electrode. The reference electrode’s role is to act as a reference in measuring and controlling the working electrode potential, without passing any current. The reference electrode should have a constant electrochemical potential at low current density. Electrodes, the working, reference, and auxiliary make up the modern three …

Are batteries afraid of the cold in winter? – Semco university

Leave a Comment / Electric Vehicles / By

Introduction Do you often let your car “test” in danger? In fact, it’s cold, and it’s easy to “freeze” the battery when going out on an electric bike. Therefore, if you want to be more secure when you go out, you need to know about battery antifreeze (batteries afraid of the cold in winter). With …

Volume expansion in shelving stage – Semco University

Leave a Comment / General / By

Introduction Lithium-ion batteries are accompanied by volume expansion, including structural expansion and gas production expansion, during the process of formation, cycling, storage, and overcharging. The charge-discharge rate determines the rate of the lithium-deintercalation reaction of the battery cell, and it is also accompanied by different degrees of heat generation or lithium evolution. When researchers study …
