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 …

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 …
