With advances in material synthesis and process technologies, a lot of unique electronic devices could be developed. As a result, a very stable and long life time based energy source is strongly required. Thin film battery (TFB) is a good candidate for satisfying this requirement. Although the TFB has high energy density, it exhibits shortage problem in energy saving amount. To enhance the capacity of TFB, increase thickness of cathode layer has been proposed. However, thick cathode by conventional thick film process cannot give optimal surface roughness for adopting in thin film solid electrolyte. In this presentation, very high capacitive 2-Dimensional all solid state Li ion batteries is shown. Deposition of solid electrolyte could be possible due to well controlled surface morphology of the thick cathode layer. Based on this thick cathode and thin film solid electrolyte, all solid state battery with energy density of 2 mAh/cm2 was prepared.
