“…In the search for more affordable catalytic materials, a number of researchers have devoted their effort to developing metal oxide catalysts with high activity and to utilising them in MABs. [116][117][118][119][120][121][122][123][124][125][126] In particular, spinel-type transition metal oxides have attracted great attention as catalytic materials for MABs due to their relatively low cost and high activity. Spinel-type transition metal oxides based on Co, Mn and/or Ni have been reported to exhibit strong bi-functionality towards the ORR and OER in aqueous alkaline electrolytes: 11,89,127 ORR-OER:…”

Porous nanoarchitectures of spinel-type transition metal oxides for electrochemical energy storage systems AbstractTransition metal oxides possessing two kinds of metals (denoted as AxB3-xO4, which is generally defined as a spinel structure; A, B = Co, Ni, Zn, Mn, Fe, etc.), with stoichiometric or even non-stoichiometric compositions, have recently attracted great interest in electrochemical energy storage systems (ESSs). The spinel-type transition metal oxides exhibit outstanding electrochemical activity and stability, and thus, they can play a key role in realising cost-effective and environmentally friendly ESSs. Moreover, porous nanoarchitectures can offer a large number of electrochemically active sites and, at the same time, facilitate transport of charge carriers (electrons and ions) during energy storage reactions. In the design of spinel-type transition metal oxides for energy storage applications, therefore, nanostructural engineering is one of the most essential approaches to achieving high electrochemical performance in ESSs. In this perspective, we introduce spinel-type transition metal oxides with various transition metals and present recent research advances in material design of spinel-type transition metal oxides with tunable architectures (shape, porosity, and size) and compositions on the micro-and nano-scale. Furthermore, their technological applications as electrode materials for next-generation ESSs, including metal-air batteries, lithium-ion batteries, and supercapacitors, are discussed.

“…The charging or discharging period was 300 s for each state, and thus this was essentially one accelerated degradation test. Similar test methods using C-D cycles have previously been used for zinc air batteries [3,8,9]. A current density of 15 mA· cm −2 and 25 mA· cm −2 was used for the charging and discharging process, respectively.…”

An electrically rechargeable zinc-air battery stack consisting of three single cells in series was designed using a novel structured bipolar plate with air-breathing holes. Alpha-MnO2 and LaNiO3 severed as the catalysts for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). The anodic and cathodic polarization and individual cell voltages were measured at constant charge-discharge (C-D) current densities indicating a uniform voltage profile for each single cell. One hundred C-D cycles were carried out for the stack. The results showed that, over the initial 10 cycles, the average C-D voltage gap was about 0.94 V and the average energy efficiency reached 89.28% with current density charging at 15 mA· cm −2 and discharging at 25 mA· cm −2 . The total increase in charging voltage over the 100 C-D cycles was ~1.56% demonstrating excellent stability performance. The stack performance degradation was analyzed by galvanostatic electrochemical impedance spectroscopy. The charge transfer resistance of ORR increased from 1.57 to 2.21 Ω and that of Zn/Zn 2+ reaction increased from 0.21 to 0.34 Ω after 100 C-D cycles.The quantitative analysis guided the potential for the optimization of both positive and negative electrodes to improve the cycle life of the cell stack.

“…3(a), the primary battery showed a high open circuit voltage of ~1.325 V. At a voltage of 1.0 V, it gave a high current density of 200.6 mA cm -2 . The peak power density could reach as high as 293.2 mW cm -2 at 0.7 V, much better than that of most recently reported Zn-air primary battery [6]. In addition, our catalyst has much higher peak power density compared with Pt/C (120.8 mW cm −2 ) under the same measuring conditions.…”

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
