To develop a high-capacity rechargeable aluminum–air battery with resistance toward the degradation induced by long-term charge–discharge electrochemical reactions, non-oxide ceramic materials, e.g., TiN, TiC, and TiB2, were used as air cathode materials with the ionic liquid 1-ethyl-3-methylimidazolium chloride as the electrolyte.

Li -rich layer-structured x Li 2 MnO 3 ⋅ (1 - x) LiMO 2 ( M = Mn , Ni , Co , etc.) materials have attracted much attention due to their extraordinarily high reversible capacity as the cathode material in Li -ion batteries. To better understand the nature of this type of materials, this paper reviews history of development of the Li -rich cathode materials, and provides in-depth study on complicated crystal structures and reaction mechanisms during electrochemical charge/discharge cycling. Despite the fabulous capability at low rate, several drawbacks still gap this type of high-capacity cathode materials from practical applications, for instance the large irreversible capacity loss at first cycle, poor rate capability, severe voltage decay and capacity fade during electrochemical charge/discharge cycling. This review will also address mechanisms for these inferior properties and propose various possible solutions to solve above issues for future utilization of these cathode materials in commercial Li -ion batteries.

The effects of electrolyte, catalyst, and the process of preparation of the air-cathode on the performance of Li-air batteries were investigated. An ether based electrolyte was the best choice for Ketjen Black carbon based air cathodes and delivered high specific capacity (1050 mAh/gC) under dry air with cobalt oxide as catalyst. The introduction of an ultrasonication step in the air-cathode fabrication process improved the air-cathode microstructure. BET analyses revealed that the cathode has a higher surface area and mesopore volume when ultrasonication was used compared to those for the cathode fabricated without the ultrasonication step. With the optimized electrolyte and air-cathode, a high capacity of 2620 mAh/gC was obtained for Li-air batteries tested in dry air with a 0.1 mA/cm2 current density.

ABSTRACTProperties and characteristics of hydriding alloys are strongly dependent on surface compositions and morphologies. For instance, oxides such as La203 on AB5 alloys and ZrO2 on AB2, AB, and body-centered-cubic (BCC) alloys act as the barriers for the conversion of molecular and ionic hydrogen to atomic hydrogen at the surface, thus reducing the kinetics in both the gas-solid and electrochemical reactions.Alloy surfaces chemically treated by an aqueous F-ion containing solution have been developed to solve such problems. F-treated surfaces exhibit significantly improved characteristics in regard to the hydrogen uptakes and the protection against impurities and electrolyte solution. In addition, highly conductive metallic Ni layers can be formed on the surface of the alloy particles by the fluorination.The authors report the properties and characteristics of fluorinated hydriding alloys, mainly of a typical AB2 Laves phase material which represents the difficult activation characteristics and poor long-term durability during electrochemical charge/discharge cycles.

Aqueous zinc batteries are considered as one of the most promising energy storage systems for large-scale energy storage and wearable electronics, owing to their low cost and intrinsic safety. However, cathode materials that can reversibly host Zn<sup>2+</sup> are still less. Here, we demonstrate that two N-containing organic compounds, hexamethoxy hexaazatrinaphthylene (HMHATN) and hexaazatrinaphthylene (HATN), used as cathodes can exhibit excellent reversible Zn<sup>2+</sup> storage capability with fast kinetics and the high capacity of 542 and 963 mA h g<sup>-1</sup>, respectively. The Zn//HMHATN and Zn//HATN full batteries display the high energy density of 160 and 221.6 W h kg<sup>-1</sup>, respectively, and long-term cycling stability. Further, we investigate the mechanism of Zn<sup>2+</sup> storage in the cathodes. More importantly, the flexible aqueous Zn//HMHATN and Zn//HATN batteries fabricated also have high capacity, long-term cycling life and impressive energy density, displaying its application prospect in wearable electronics. Our work opens a new system for finding organic cathode materials used in aqueous zinc batteries.
