With strong security and reliability,high energy density,high voltage,long cycle life and many other advantages, all solid state thin film lithium rechargeable batteries have become good choices for micro-electronic devices. Due to the fact that they are the key components of all solid state thin film lithium rechargeable batteries, research and development on cathode,anode,and solid electrolyte are of great importance. This paper firstly reviews cathode, anode, as well as solid electrolyte which are recently applied more preferably, and their physical properties, electrochemical properties and the main methods of preparation of them are described. Properties of batteries are also depended on design of the cell structure. Influence on charge and discharge properties because of cell structure is presented and the future development and research focus are expected as well.
