NASICON (Sodium super ionic conductor) structured Li1.5Al0.5Ge1.5(PO4)(3) (LAGP) solid electrolyte is synthesized through a solid state reaction. The total conductivity of the LAGP electrolyte is 7 x 10(-5) S cm(-1) with a potential window larger than 6 V. All solid state lithium batteries are fabricated using LiMn2O4 as a cathode, LAGP as an electrolyte and lithium metal as an anode. The LiMn2O4/LAGP/Li cell can deliver a capacity of about 80 mAh g(-1) in the first discharge cycle and increases gradually with charge/discharge cycles, indicating that LAGP can be used as a promising electrolyte for lithium rechargeable batteries.
