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.

Based on an inexhaustible and ubiquitous source of oxygen, the lithium-oxygen batteries are currently the subject of much scientific investigation because of their potential for extremely high energy density. The electrocatalytic materials for them have been extensively researched during the past decade. Even though they are a key component in the lithium-oxygen batteries, however, the study of electrolytes is still in its primary stage. Electrolytes have an important influence on the electrochemical performance of lithium-oxygen batteries, especially on their cycling stability and rate capacity. Therefore, it is important to select an ideal electrolyte with excellent stability against attack by reaction intermediates, along with excellent oxygen solubility and diffusivity. In this review, the physicochemical and electrochemical properties of organic electrolytes for lithium-oxygen batteries are discussed and compared. Furthermore, possible research directions are proposed for the development of an ideal electrolyte for enhanced electrochemical performance.

Unlike the intercalation mechanism of lithium-ion batteries or sodium-ion batteries, the Li-O 2 battery systems employ a dissolution/ deposition reaction with an air electrode that uses oxygen as the cathode electrode during the electrochemical processes. Research on the Li-O 2 battery is complicated by the need for exposure the air cathode to O 2 atmosphere.Many advances have been achieved, which include advances on cathode materials, electrolytes, anode materials, and redox mediators. [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] Several excellent reviews have been published to summarize recent developments and our current understanding of Li-O 2 batteries, especially with respect to the cathode electrocatalytic materials. [25][26][27][28][29][30][31][32][33][34][35] These reviews have comprehensively discussed the relationship between the structure of electrocatalytic materials and the electrochemical performance of Li-O 2 batteries. There are, however, few reviews focused on the effects of different electrolytes on the electrochemical performance of the Li-O 2 batteries. [36][37][38] For the aqueous Li-O 2 batteries, LiOH is generated or oxidized at the cathode during discharge and charge processes because H 2 O and O 2 are involved in the reactions. In the case of the nonaqueous Li-O 2 batteries, there are two essential processes that determine their electrochemical performance: the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). During the ORR process, the Li 2 O 2 is precipitated as the final discharge product on the air cathode, while during the OER process, Li 2 O 2 is then decomposed and the O 2 is regenerated. Therefore, there are huge differences between aqueous and nonaqueous Li-O 2 batteries. Since the nonaqueous Li-O 2 batteries have dominated ...
