锂离子导电膜很少被研究，尽管它们对于建造由水和非水电解液组成的长期运行的锂空气电池是必不可少的。采用射频溅射技术在掺B_2O_3的磷酸铝锂(B-LAGP)衬底上制备了磷氧氮锂(LiPON)薄膜。致密的无定形LiPON薄层可以作为B-LAGP的保护层，使其与锂金属电极分离，并减缓它们之间的反应。LiPON/B-LAGP固体电解质具有较大的电化学稳定窗口(0-5V)，在所有锂基电池中具有良好的应用前景。采用LiPON/B-LAGP固体电解质的具有保护锂电极结构的非质子型Li-O2电池具有合理的循环稳定性，在1000 mA/h的−1极限容量下，循环寿命长达52次。
Lithium ion conducting membranes are barely studied, although they are essentially indispensable for building Li-air batteries composed of aqueous and non-aqueous electrolytes for long-term operation. Lithium phosphorous oxynitride (LiPON) thin films were deposited by RF-sputtering technique on B2O3-added lithium aluminum germanium phosphate (B-LAGP). Compact thin amorphous LiPON layer could act as a protective interlayer for B-LAGP by separating it from Li metal electrode and mitigate the reaction between them. Large electrochemical stability window (0–5 V) of LiPON/B-LAGP solid electrolyte shows promising feasibility for applications in all lithium based batteries. The aprotic Li-O2cell with protected lithium electrode configuration employing LiPON/B-LAGP solid electrolyte has exhibited reasonable cycling stability with long-life of 52 cycles at a limited capacity of 1000 mA h g−1.
