Abstract: | The present work was based on the investigation of different thin film components of Li ion batteries. A first part was dedicated to the deposition of cathodes in thin film form of a known material, LiCoO2, and an alternative one, Li(NiMnCo)O2 employing physical vapor deposition (PVD) and chemical vapor deposition (CVD), respectively. A second part was focused on the cathode-electrolyte interface for three case studies: 1) as deposited LiCoO2 cathode thin film, 2) ZrO2 coated LiCoO2 thin film and 3) LiPON coated LiCoO2 thin film. The interface cathode-electrolyte of these three cases were studied before and after galvanostatic cycling to determine surface layer characteristics and changes arising on the interface after battery operation. The interface of a bare LiCoO2 layer was further studied after soaking in liquid electrolyte to elucidate the effect of short storage procedures in batteries. Additionally, LiPON thin films were studied on the basis of structural changes occurring with nitrogenation and its correlation to a possible mechanism during ion conduction. Composition of phosphate glasses with rf sputtering was proven to be greatly influenced by the gas ratio employed. |
