Role of Transport in the First Atomic Layers of Nanoparticles in Lithium Batteries

Abstract : A theoretical approach of the insertion/deinsertion of lithium in host materials is proposed to take into account some phenomena not included in classical analyses of lithium battery operation. This is mainly related to the variation of the transport properties in the first atomic layers in the vicinity of the interface which can give rise to rapid storage phenomena. These processes are of great importance in the case of electrodes made of nanoparticles as a result of the considerable development of the interfacial surface. For example, they can be at the origin of the important capacitive behavior of the system. A model based on the numerical integration of transport equations is presented to describe these complex mechanisms. The theoretical analysis is illustrated on the model case of lithium insertion in electrodes made of nanoparticles of anatase and fluorinated anatase.
