What Is The SEI, And What Effect Does It Have On The Battery?
The SEI (solid electrolyte interphase) is formed on the surface of the anode from the electrochemical reduction of the electrolyte and plays a crucial role in the long-term cyclability of a lithium-based battery. Introduction of SEI During the first charge and discharge of a lithium-ion battery, the electrode material reacts with the electrolyte at the solid-liquid […]
