Letter

Recently, there has been an interest in the development of Li-Air batteries for high energy applications. One configuration involves the use of a Li anode in a non-aqueous electrolyte, which is separated from an aqueous electrolyte containing the air cathode by a solid-state Li-ion conducting membrane [1, 2, 3, 4]. One of the major requirements for the membrane is high Li-ion conductivity, which has resulted in renewed interest in the use of LiTi2(PO4)3 (LTP) as a potential membrane [1, 2, 3, 4, 5]. In the above configuration, the chemical stability of the membrane with water is also a major concern. In this regard, the water stability of Al-doped LTP has been investigated by weight loss, X-ray diffraction, and ionic conductivity before and after immersion in distilled water [4, 6]. Cretin et al. [6] found approximately a 0.9% weight loss for a solid Al-doped LTP sample, with a relative density of ~95%, after immersion in distilled water for 100 h at room temperature. Hasegawa et al. [
