Abstract

A thin film battery has been fabricated by depositing a LiCoO2 positive electrode, a Li1.9Si0.28P1.0O1.1 N1.0 electrolyte, and Si0.7V0.3 negative electrode, sequentially. The electrochemical characteristics of the Si0.7V0.3 electrode and the electrical conductivity of the Li1.9Si0.28P1.0O1.1 N1.0 electrolyte are investigated. The thin film battery mainly operates in the voltage range between 3 and 3.5 V. It exhibits excellent cycling stability when cycled between 2.0 and 3.9 V, while the battery performance is abruptly deteriorated when the charge cutoff voltage is extended to 4.2 V.
