Interphases Between Electrolytes and Anodes in Li-Ion Battery

Abstract The successful application of lithium-ion batteries depends to a great extent on the existence of interphases at anodes. In this chapter, the role and the significance of interphases in lithium-ion batteries are introduced firstly, then the theories proposed before 2005 are outlined, and the latest research progresses are reviewed at last, mainly focused on the formation processes, chemistries, and properties of the interphases on graphite. 

Interface, called boundary as well, results from the contact of two different phases. The electrode/electrolyte interface is necessary for an electrochemical system, because it provides valid locations where electron exchange is participating and the
