An overview of aqueous lithium-ion batteries

Although the lithium-ion battery using aqueous solution as electrolyte has low energy density, it may solve both the safety and large cost problems for lithium-ion batteries that use highly toxic and flammable organic solvents, and the poor cycling life associated with commercialized aqueous rechargeable batteries including lead-acid and nickel-metal hydride batteries, showing promising application in stationary power sources for smart grid. The present work reviews the latest advances in the exploration and development of battery systems and related materials. Also the main challenges in this field are briefly discussed and some constructive views and possible solutions are provided. On the other hand, present work also reviews the recent progress of the application of Li-metal anode, and analyzes its advantage, disadvantage and challenge.
