Special Issue Information

Dear colleagues,

Rechargeable lithium batteries have become the most widespread devices for electrochemical energy storage for nomad systems (portable electronics, electric vehicles, etc.). Indeed, Li-ion technology has reached the zenith of its development (in terms of anode and cathode materials), and relatively little room is available for further improvements in terms of cost and specific capacity. Efforts are, however, needed to tackle issues related to safety and electrolytes. Today, however, such technology is not ready, alone, to meet some of the requested performance, cost, and environmental requirements. The present situation has thus encouraged scientists to diversify explored technologies, including some that have long fallen into oblivion. Among the considered alternative technologies, Na-ion, K-ion, multivalent-ion (mainly Mg-ion), Li-sulfur, Li-air, and redox-flow batteries are some of the ones that have been covered the most in the last decade.

This Special Issue intends to underline the cutting-edge advances in alternative technologies for electrochemical energy storage. It aims to cover new materials, strategies, and designs but also the advances in characterization tools such as operando spectroscopies (XAS, IR, Raman, NMR, and Mössbauer), microscopy, and diffraction methods used for the specific development of new technologies beyond Li-ion batteries.

Rechargeable aprotic lithium-oxygen (Li-O2) batteries have attracted significant interest in recent years owing to their ultrahigh theoretical capacity, low cost, and environmental friendliness. However, the further development of Li-O2 batteries is hindered by some ineluctable issues, such as severe parasitic reactions, low energy efficiency, poor rate capability, short cycling life and potential safety hazards, which mainly stem from the high charging overpotential in the positive electrode side. Thus, it is of great significance to develop high-performance catalysts for the positive electrode in order to address these issues and to boost the commercialization of Li-O2 batteries. In this review, three main categories of catalyst for the positive electrode of Li-O2 batteries, including carbon materials, noble metals and their oxides, and transition metals and their oxides, are systematically summarized and discussed. We not only focus on the electrochemical performance of batteries, but also pay more attention to understanding the catalytic mechanism of these catalysts for the positive electrode. In closing, opportunities for the design of better catalysts for the positive electrode of high-performance Li-O2 batteries are discussed. Full article
