Unraveling Polysulfide's Adsorption and Electrocatalytic Conversion on Metal Oxides for Li‐S Batteries

Lithium sulfur (Li-S) batteries possess high theoretical capacity and energy density, holding great promise for next generation electronics and electrical vehicles. However, the Li-S batteries development is hindered by the shuttle effect and sluggish conversion kinetics of lithium polysulfides (LiPSs). Designing highly polar materials such as metal oxides (MOs) with moderate adsorption and effective catalytic activity is essential to overcome the above issues. To design efficient MOs catalysts, it is critical and necessary to understand the adsorption mechanism and associated catalytic processes of LiPSs. However, most reviews still lack a comprehensive investigation of the basic mechanism and always ignore their in-depth relationship. In this review, a systematic analysis toward understanding the underlying adsorption and catalytic mechanism in Li-S chemistry as well as discussion of the typical works concerning MOs electrocatalysts are provided. Moreover, to improve the sluggish "adsorption-diffusion-conversion" process caused by the low conductive nature of MOs, oxygen vacancies and heterostructure engineering are elucidated as the two most effective strategies. The challenges and prospects of MOs electrocatalysts are also provided in the last section. The authors hope this review will provide instructive guidance to design effective catalyst materials and explore practical possibilities for the commercialization of Li-S batteries.

“…In addition, the mesoporous structures constructed by CNTs and rGO can adapt to the volume changes of SnO 2 NPs and form more stable SEI layers during repeated discharge/charge processes. Moreover, Graphene/CNTs composites could also promote the cathode function of LIBs [ 65 , 66 , 67 , 68 ] and inhibit the dendrite formation of the lithium anode of lithium-ion batteries [ 69 ], providing more opportunities for a huge increase in battery capacity and energy density. The addition of Graphene/CNTs composites helps to solve the existing problems such as slow reaction kinetics, polysulfide diffusion caused by insulating sulfur, and severe capacity loss, and further promotes the development of LIBs in the next generation of energy storage systems.…”

In response to the exhaustion of traditional energy, green and efficient energy conversion has attracted growing attention. The IVA group elements, especially carbon, are widely distributed and stable in the earth’s crust, and have received a lot of attention from scientists. The low-dimensional structures composed of IVA group elements have special energy band structure and electrical properties, which allow them to show more excellent performance in the fields of energy conversion. In recent years, the diversification of synthesis and optimization of properties of IVA group elements low-dimensional nanomaterials (IVA-LD) contributed to the flourishing development of related fields. This paper reviews the properties and synthesis methods of IVA-LD for energy conversion devices, as well as their current applications in major fields such as ion battery, moisture electricity generation, and solar-driven evaporation. Finally, the prospects and challenges faced by the IVA-LD in the field of energy conversion are discussed.
