Aging Effects to Solid Electrolyte Interface (SEI) Membrane Formation and the Performance Analysis of Lithium Ion Batteries

Solid electrolyte interface (SEI) membrane was fabricated in the first electrochemical charged and further sensitively grow in an aging storage of battery. This research demonstrates a new interesting SEI membrane fabrication in the first electrochemical charging “coincides” with aging treatment occurring in the lithium ion battery formation that the results revealed electrolyte effects to SEI membrane composition and the cycling enhancement of battery performance. The research also discusses the SEI membrane composition and the growing morphology on MCMB electrode in the varying formation temperatures examine that the SEI membrane influences rate/cycling performance of the advanced lithium battery (ALB) with two kinds of electrolytes (EC/PC/DEC and EC/EMC). Within the framework of this new perspective work, we can dramatically offer and account for the SEI membrane mechanism while the battery are going to charge coincide with aging called aging-formation to demonstrate the SEI membrane properties combined with electrolytes and aging condition concerning the battery performance.
