|Thin-film solid-state rechargeable batteries on silicon are ideal power sources for microsystems applications, where a high level of integration is required. This paper presents a lithium solid-state thin-film battery for integration in stand-alone microsystems. The thin-films were deposited by direct current (DC) and radio-frequency (RF) reactive sputtering techniques. The materials of the battery includes SnO2, Li3PO4N and LiCoO2 as anode, electrolyte and cathode, respectively. The SnO2 gives the battery a maximum storage capacity of 781 mAhg-1, the LiCoO2 can maintain a capacity of 140 mAhg-1. The two materials used as anode and cathode with the Li3PO4N as electrolyte can obtain an output voltage in the range 3-4.2 V.
