Special Issue Information

Dear Colleagues,

The rapid development of new-energy vehicles has prompted scientists and governments to seek high-energy storage systems. Metal-air (metal–O2 or metal–CO2) batteries, a promising battery system, have received researcher attention because of their high energy density and environmental friendliness. However, the use of metal-air batteries is challenging due to a number of obstacles that limit their high energy density output. Popular strategies for overcoming this issue are dependent on the electrode materials as well as on the electrolyte. With this in mind, the exploration of promising electrode materials, electrolytes, and even field-assisted technologies will be of great interest to scientists and engineers in the field of metal-air batteries.

This Special Issue, titled “Material Design and Mechanism Research of Metal-Air Batteries”, welcomes original research and reviews in this field and focuses on all aspects of the design, characterization, evaluation, and development of novel electrode materials, electrolytes, and this new metal-air battery system. We cordially invite authors to contribute reviews or research articles to our Special Issue.

All article research submissions should involve research at the molecular level as well as verified experiments.

Ge/RuO2 nanocomposites were successfully fabricated as anode materials for lithium-ion batteries using RuO2 nanosheets and Ge/GeO2 nanoparticles (NPs). X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAS) analyses showed that elemental Ge nanoparticles were distributed onto the rutile-type RuO2. Transmission electron microscopy images showed well-dispersed Ge nanoparticles embedded in rutile-type RuO2. The Ge/RuO2 nanocomposite maintained higher discharge capacities (471 mA h g−1) after the 90th cycle at 0.1 A g−1 than that (211 mA h g−1) of Ge/GeO2 nanoparticles. The Ge/RuO2 nanocomposite exhibited a higher capacity retention than Ge/GeO2 NPs. These results suggest that the well-dispersed Ge nanoparticles within RuO2 matrices enhance the cycle stability and capacity retention of the anode material. Full article

Facing the challenges of energy crisis and global warming, the development of renewable energy has received more and more attention. To offset the discontinuity of renewable energy, such as wind and solar energy, it is urgent to search for an excellent performance energy storage system to match them. Metal–air batteries (typical representative: Li–air battery and Zn–air battery) have broad prospects in the field of energy storage due to their high specific capacity and environmental friendliness. The drawbacks preventing the massive application of metal–air batteries are the poor reaction kinetics and high overpotential during the charging–discharging process, which can be alleviated by the application of an electrochemical catalyst and porous cathode. Biomass, also, as a renewable resource, plays a critical role in the preparation of carbon-based catalysts and porous cathode with excellent performance for metal–air batteries due to the inherent rich heteroatom and pore structure of biomass. In this paper, we have reviewed the latest progress in the creative preparation of porous cathode for the Li–air battery and Zn–air battery from biomass and summarized the effects of various biomass sources precursors on the composition, morphology and structure-activity relationship of cathode. This review will help us understand the relevant applications of biomass carbon in the field of metal–air batteries. Full article
