“…The IR drop in the two electrode system is much higher than in the 3-electrode system. This has also been observed in other hybrid electrolyte systems [18][19][20][21]23]. The possible reason is that the solid electrolyte has a low lithium diffusion coefficient, which limits the rate capability of this system.…”

The all-solid-state Li-air battery has been fabricated, which is constructed by a lithium foil anode, a NASICON-type solid state electrolyte Li1+xAlyGe2-y(PO4)3 (LAGP) and single-walled carbon nanotubes (SWCNTs)/LAGP nanoparticles composite as air electrode. Its electrochemical performance was investigated in air atmosphere. Particularly, this battery exhibited a larger capacity about 2800 mAh g(-1) for the first cycle, while comparatively the battery with multiwalled carbon nanotubes (MWCNTs)/LAGP as cathode had a capacity of only about 1700 mAh g(-1). Also, the battery with SWCNTs/LAGP showed improved cycling performance with a reversible capacity of 1000 mAh g(-1) at a current density of 200 mA g(-1). Our result demonstrated that the all-solid-state Li-air battery with SWCNTs/LAGP as cathode catalyst has a considerable potential for practical application.

Several key issues of aqueous lithium/air rechargeable batteries that consists of a water-stable lithium electrode, an aqueous electrolyte, and a bifunctional air electrode are reviewed. Based on research and discussion of these issues, the challenges and prospects for high energy density aqueous lithium/air rechargeable batteries are described. From a broader perspective, lithium/air rechargeable batteries that employ aprotic electrolytes are also briefly introduced for comparison. Ç IntroductionDuring the past few years, lithium/air rechargeable batteries have received significant attention, due to their potential for development as a high energy density battery for electric vehicles (EVs). The number of research papers on lithium/air batteries has increased year by year. The sharp increase in interest is motivated by the high theoretical energy density of lithium/air batteries (11140 W h kg ¹1 , excluding oxygen), which is comparable with that of 13000 W h kg ¹1 for gasoline 1 and such an energy density would be applicable for EV batteries with an acceptable driving range. There is high expectation for high energy density lithium/air batteries to serve as power sources to drive pure EVs, which would contribute to a reduction in global greenhouse gas emissions and address the crisis of fossil energy source exhaustion.Two types of lithium/air batteries have been studied, nonaqueous and aqueous electrolyte systems. Two possible cell reactions for the nonaqueous electrolyte system areand 2Li þ 1=2O 2 ) Li 2 O ð2Þ The reversible cell voltages for reactions (1) and (2) are 2.959 and 2.913 V, respectively. It has been demonstrated that reaction (1) is reversible, whereas reaction (2) is irreversible. 2The energy density of 3456 W h kg ¹1 (including oxygen) is calculated using reaction (1). In an aqueous electrolyte, water molecules are involved in the reaction according to the following reaction:The reversible cell voltage for reaction (3) is 3.84 V in a neutral solution, and the energy density (including oxygen) is 2450 W h kg ¹1. The energy density of the aqueous system is approximately 30% lower than that of the nonaqueous system (including oxygen).It is well known that lithium reacts vigorously with water to produce LiOH and hydrogen gas. Therefore, to avoid this parasitic reaction, most research on lithium/air batteries have focused on using aprotic organic solvents as electrolytes. In the case of using aprotic electrolytes, Bruce and colleagues have given a preliminary demonstration using gravimetric analysis and in situ mass spectrometry that Li 2 O 2 formed upon discharge was decomposed to Li and O 2 during a charge cycle, both with and without a catalyst.2 However, there are some severe problems that must still be addressed, such as lithium corrosion by water and CO 2 ingression when operated in air (poor lifetime), precipitation of Li oxides on the porous cathode (low capacity), and high polarization resistance of the air electrode (low energy conversion efficiency). These problems could be removed...
