Abstract
Besides being of technological interest, thin films of different battery components, especially active cathode materials, can be utilized for fundamental studies of the processes that govern the battery’s properties. Cathodes utilized in commercial lithium batteries are complex systems consisting of a polycrystalline active material in the form of a powder mixed with conductive carbon and a binding material. A simple system with no additives is desirable for use in the investigation of interfacial reactions, especially for local microstructural studies by transmission electron microscopy (TEM). Such systems, when synthesized in the form of a thin film, especially as a single (or pseudo-single) crystal epitaxial film, can provide powerful insight into the processes occurring on a well-described two-dimensional interface, as well as the film interior. In our recent works we successfully utilized LiCoO2 epitaxial films to study details of structural changes during electrochemical cycling. In the work presented here the similar approach was extended to other important cathode systems, as well as for studying some solid electrolytes Recent Publications: 1.
