Abstract

The electrochemical performance of an all-solid-state lithium-oxygen battery was examined using a platinum patterned electrode with a lithium conducting solid electrolyte under a humidified O₂ atmosphere. The cell consisted of a lithium metal anode, a protective layer of polyethylene oxide with Li(CF₃SO₂)₂N, a lithium-conducting solid electrolyte of Li₁ ₊ _x ₊ _yAl_x(Ge,Ti)_{2 - x}Si_yP_{3 - y}O₁₂, and a sputtered platinum stripe-patterned air electrode. The open circuit voltage (OCV) of the virgin cell was 3.5 V under humidified O₂ and decreased to 3.2 V after slight discharge, which is comparable with that under dry O₂ (2.4 V). The cell was successfully discharged and charged at 0.1 mA cm^{- 2} and 60 °C. A reaction product was observed on the platinum electrode; however, it could not be identified by X-ray diffraction analysis or Raman spectroscopy, which indicated it was amorphous. Nano-secondary ion mass spectrometry (SIMS) analysis suggested that the reaction product contains Li, H, and O.
