Aqueous rechargeable lithium batteries (ARLBs) are a rechargeable battery system containing lithium intercalation compounds as electrode(s). Since their finding in 1994, the progress on improving their performance was very limited. Since 2005, our laboratory initiated frontier research work on this field. Now, their rate performance, reversible capacity and cycling life have been markedly improved. For example, their cathode materials such as LiCoO2 and LiMn2O4 can charge and discharge at 10000 mA/g, which is much better so far than any other electrode materials for batteries, and the reversible capacities can arrive at the same levels in organic electrolytes. After 10000 full cycles at 10C, the retention of the reversible capacity is above 93%. Their anode materials such as LiV3O8 and polypyrrole can also charge and discharge at very large current densities with little capacity fading.
