“…At present, the practicable bifunctional catalysts for Li–O 2 batteries mainly include carbon materials, precious metals and their alloys, and transition metal oxides (TMOs). − In recent years, transition metal sulfides (TMSs) have also been in the spotlight due to their low price and excellent electronic and electrochemical properties, and some promising results have been achieved in this regard. − As a member of TMSs, SnS 2 is cheap and easy to prepare and can be successfully synthesized into nanostructures with controllable morphology by a variety of synthetic methods. , Due to the graphene-like layered structure, SnS 2 has many applications in electrochemical devices including Li-ion batteries, photoelectronics, sensors, fuel cells, and so on. − Our research group explored the catalytic properties of SnS 2 with different morphologies and found that a Li–O 2 battery based on plate-like SnS 2 exhibits superior performance compared to a battery with flower-like SnS 2 material judging from the ORR/OER kinetics, specific discharge capacity, rate capability, and life span. However, the cycleability of a plate-like SnS 2 -based battery is still unsatisfactory and needs promotion.…”
