A solid-state half-cell structure with a Sn--Li2O composite (SLC) anode/LiPON/Li was prepared to improve upon the cycling stability at the second discharging cycle of the non-Li anode thin films for all-solid-state batteries. Based on the cycling behaviors of the all-solid half cell with SLC and pure Sn thin film electrodes at first and second discharging cycles, cycling stability at the initial charging--discharging cycle of the all-solid-state battery system was improved. The high retention value of SLC thin film electrodes with LiPON solid electrolyte might originate from (1) the structural stability of the SLC thin film, and (2) suppression of crack formation at the SLC surface owing to an increasing surface mechanical strength of the SLC thin film by the LiPON deposition on it. These results indicate that the SLC thin film has a high possibility as the stable solid anode material for use as an all-solid-state battery.
