“…The mechanism is similar to the MnO x -catalyzed pseudo fourelectron O 2 reduction in an alkaline electrolyte. [15] This finding is critical to the Li-air battery application. As was mentioned in the introduction, the chemical reaction between nonaqueous solvents, for example, PC and O 2 À , not only consumes the solvent in the electrolyte, but also gives chemicals (e.g., Li 2 CO 3 ) that are difficult to reoxidize.…”

Tris(pentafluorophenyl)borane (TPFPB) was found to be an efficient catalyst for rapid superoxide (O2(-)) disproportionation. The kinetics for the catalytic disproportionation reaction is much faster than the reaction between O2(-) and propylene carbonate. Therefore, the negative impact of the reaction between the electrolyte and O2(-) produced by the O2 reduction is minimized. The cathodic current for O2 reduction can be doubled in the presence of TPFPB. The high reduction current resulted from the pseudo two-electron O2-reduction reaction due to the replenishment of O2 at the electrode surface. This discovery could lead to a new avenue for the development of high-capacity, high-rate, rechargeable Li-air batteries.

“…Generally, accompanied with the increase of NiO content, the maximum output voltage was growing to some extent while the cell setup time was decreased because more bacteria were available to attach onto the anode, furthermore, enhanced ORR by providing more activity sites for oxygen attachments leading to increasing the rate of electron transferred from anode to cathode. In other words, bacterial adhension could be enhanced which may be contributed to more negative of anode potential and accelerated by NiO to enhance the effective catalyzing for hydrogen peroxide decomposition (Ominde et al, 2010). These resulted in the shortening of startup time.…”

“…Hence the characterizations of anode not only provide a suitable place for bacterial attachments but also enhance the conductivity of the whole MFC. Up to now, researches have been frequently carried out involving the anode of MFC (Logan and Cheng., 2007;Karra et al, 2012;Popov et al, 2012;Park et al, 2013;Su et al, 2012;Zou et al, 2008), but the explorations of MFC cathode catalysts have been relatively limited when comparing with the researches of anode (Pu et al, 2014;Yang et al, 2014;Zhang et al, 2014). The electrocatalysts with high oxygen reduction reaction (ORR) efficiency are the key electrode materials for MFCs (Feng et al, 2011).…”

Summary Metal–air batteries are being envisioned as a clean and high energy fuel for the modern automotive industry. The lithium–air battery has been found most promising among the various practically applicable metal–air systems, that is, Al–air, Li–air, Mg–air, Fe–air, and Zn–air. The theoretical specific energy of the Li–air battery is ~12 kWh/kg, excluding the oxygen mass. This is comparable with the energy density of gasoline, which is ~13 kWh/kg. It has been hypothesized that the Li–air battery could supply an energy ~1.7 kWh/kg after losses from over potentials to run a vehicle ~300 miles on a single charge. During the first decade of this century, a fair amount of research has been conducted on Li–air battery system. Yet, Li–air batteries could not make an industrial breakthrough, and are still in the laboratory phase since their birth. In this article, we technically evaluated the recent developments, and the inferences have been analyzed from the practical/commercial point of view. The study concludes that low discharge rate, lower number of cycles, oxidation of lithium anode, discharge products at the cathode, and side reactions inside the battery are the key limiting factors in the slow progress of Li–air batteries on an industrial scale. The ongoing researches to overcome these hurdles have also been discussed. This analysis will help the reader to understand the current standing of the lithium–air battery technology.
