Fundamental Aspects of Interface Formation and Charge Transfer

Abstract

This book treats electrodes with- and without passive layers, and electrodes in contact to solid or liquid electrolyte. Consequently, the properties of both solid-solid and solid-liquid interfaces are of interest. Moreover, both ion and electron transfer are relevant, requiring the consideration of both electronic and ionic structures. While transfer of Li-ions as major electroactive species is fundamental to the functionality of the battery cells, electron transfer is a parasitic process resulting usually in degradation. Note for the following that the usual treatments of electronic interfaces presume electronic equilibrium conditions when the interface is not polarized, which is not generally valid for electrode-electrolyte interfaces in Li-ion batteries
