Crystalline LiV3O8 and LiMn2O4 were prepared by conventional solid-state reaction and characterized by X-ray diffraction analysis. Cyclic voltammetry technique was employed to evaluate the electrochemical behaviors of LiV3O8 and LiMn2O4 in 2 mol/l LiSO4 aqueous solution, and the results show that both LiV3O8 and LiMn2O4 are very stable in this aqueous electrolyte and can be used as the negative and positive electrode material without evident hydrogen or oxygen evolution. An aqueous rechargeable lithium battery (ARLB) was fabricated by using the above two intercalation compounds as the negative and positive electrodes. This battery exhibits good cycling behavior and the average discharge voltage is about 1.04 V.
