“…On discharge, Li 2 O 2 was the main product together with a little amount of Li 2 CO 3 and HCO 2 Li observed in the FTIR spectra. The DEMS analysis of evolved gases showed that no CO 2 28 The XRD data demonstrated the presence of Li 2 O 2 at the end of the first discharge. However, the FTIR spectra provided clear evidence of electrolyte decomposition.…”

“…A fullsized transit bus employing rechargeable zinc-oxygen and nickel-cadmium hybrid battery system was demonstrated in the 1990s. 2 This battery-powered bus was designed to drive a daily range of 150-250 km with passengers on board and airconditioned. The zinc-oxygen battery in this system showed gravimetric energy densities of 200 W⋅h⋅kg −1 and volumetric energy density of 221 W⋅h⋅L .…”

“…They attributed the first peak to surface electrochemical growth of Li 2 O 2 and the second peak to the solution-mediated growth of Li 2 O 2 . The surface-adsorbed LiO 2 , formed initially in oxygen reduction process, can be dissolved in the presence solvent with a high donor number, DME, and solvent with a high acceptor number, H 2 with Li anode. The present method is not directly applicable to a practical battery, but the concept suggests that appropriate combination of solvents and additives can improve small discharge capacity due to insolubility of Li 2 O 2 .…”

This review summarizes research and development trends in lithium-oxygen (Li-O 2 ) batteries. Development of a post-lithium-ion battery is highly expected to be a means to solve the global energy problem. The metal-oxygen cell, especially the Li-O 2 cell, attracts attention, since it has much larger theoretical energy density than conventional battery systems. First, this review discusses the energy density that a battery should have from the viewpoint of power sources for electric vehicles. Then the fundamental features of various kinds of metal-oxygen batteries are explained and challenges faced by them are described. The remaining part of the review focuses on research subjects of the Li-O 2 batteries. Early works which led to the present lithium-oxygen cells are briefly presented. Then, systems using various electrolytes and their major issues are introduced. First, irreversible decomposition of the electrolyte and Li 2 O 2 deposition at oxygen cathode of an organic system are described. The effort that is directed toward the solution of dendritic growth of lithium metal anode is also introduced. Thereafter, new materials, mechanisms, and strategy that were reported recently are described with regard to each of the three electrolyte systems, respectively. These are expected to be breakthroughs to solve the serious problems, such as irreversible decomposition of electrolyte. In conclusion, the issues that should be solved with the direction of future development are mentioned.

Keywords: Bifunctional catalyst, MnO 2 nanotube catalysts, rechargeable zinc-air battery. Abstract. This paper reports the preparation and electro-catalytic activity of MnO 2 nanotube catalysts for both oxygen reduction reaction (ORR) and oxygen evolution reduction (OER) in alkaline media. The catalysts were synthesized by a simple hydrothermal method under controlling the different temperatures. Results of electrochemical characterization with emphasis on the activity of the catalyst are presented, which was demonstrated by cyclic voltammetry (CV) and linear sweep voltammetry (LSV) employing a rotating disk electrode (RDE) technique. The experiments show that the as-prepared MnO 2 catalyst with nanotube structure exhibited high electro-catalytic activity and stability during battery discharge, charge and cycling processes in 6 M KOH electrolyte. The primary Zn-air battery showed a discharge peak power density ~293 mW cm -2 , which corresponds to the energy density ~725 mA hg -1 . The rechargeable Zn-air battery exhibited a small charge-discharge voltage polarization of ~0.7 V at 10 mA cm -2 , high reversibility and stability over short charge and discharge cycles, and ~1
