For Li-LiFePO<sub>4</sub> batteries, it shows a high specific capacity of 153 mA h g<sup>−1</sup> at 0.2 C after 100 cycles and a long-term durability of 115 mA h g<sup>−1</sup> at 1.0 C after 800 cycles.

A fast and reversible oxygen reduction reaction (ORR) is crucial for good performance of secondary batteries’, but the partial knowledge of its mechanisms, especially when devices are concerned, hinders further development. From this perspective, the present work uses operando Raman experiments and electrochemical impedance spectroscopy (EIS) to assess the first stages of the discharge processes in porous carbon electrodes, following their changes cycle by cycle at initial operation. A growth kinetic formation of the discharge product signal (Li<sub>2</sub>O<sub>2</sub>) was observed with operando Raman, indicating a first-order reaction and enabling an analysis by a microkinetic model. The solution mechanism in the evaluated system was ascribed for an equivalent circuit with three time constants. While the time constant for the anode interface reveals to remain relatively constant after the first discharge, its surface seemed to be more non-uniform. The model indicated that the reaction occurs at the Li<sub>2</sub>O<sub>2</sub> surface, decreasing the associated resistance during the initial discharge phase. Furthermore, the growth of Li<sub>2</sub>O<sub>2</sub> forms a hetero-phase between Li<sub>2</sub>O<sub>2</sub>/electrolyte, while creating a more compact and homogeneous on the Li<sub>2</sub>O<sub>2</sub>/cathode surface.

However, several challenges impede its commercialization including low conductivity of sulfur itself, the severe “shuttle effect” caused by lithium polysulfides (LiPSs) during charge–discharge processes, volume expansion effects and sluggish reaction kinetics. As a solution, polar metal particles and their compounds have been introduced as the main hosts for sulfur cathode due to their robust catalytic activity and adsorption capability, effectively suppressing the “shuttle effect” of LiPSs. Bimetallic alloys and their compounds with multi-functional properties exhibit remarkable electrochemical performance more readily when compared to single-metal materials. Well-designed bimetallic materials demonstrate larger specific surface areas and richer active sites, enabling simultaneous high adsorption capability and strong catalytic properties. The synergistic effect of the “adsorption-catalysis” sites accelerates the adsorption-diffusion-conversion process of LiPSs, ultimately achieving a long-lasting Li-S battery.
