In recent years, all-solid-state lithium-ion batteries (LIBs) have attracted a great deal of attention because of their high safety and energy density. Among them, flexible thin-film all-solid-state LIBs are expected as power sources of thin devices such as smart cards and wearable devices. For this purpose, thin-film electrodes with high flexibility are required.

In this study, as a candidate for an anode material satisfying these requirements, graphene-like graphite (GLG) thin films were fabricated, and their electrochemical properties as the anode of all-solid-state battery were evaluated. The obtained GLG thin film was composed of densely stacked GLG flakes and showed high flexibility. From the results of charge-discharge measurement, the GLG thin film showed a large reversible capacity of 870 mAh g−1 as an anode of all-solid-state LIB. These results clearly demonstrated that the potential properties of the GLG thin film as a new candidate for anode material of the flexible thin-film all-solid-state LIB.
