Lithium-sulfur (Li-S) and lithium-selenium (Li-Se) batteries are both facing the cathode issues of low Coulombic efficiency and unstable cycling stability due to the severe shuttle effect of lithium polysulfides or lithium polyselenides. Simultaneously inhibiting polysulfides/polyselenides dissolution in organic electrolytes and propelling them to conversion via introducing polar, catalytic materials has been proven as an effective strategy to enhance the durability of Li-S and Li-Se batteries. In this mini review, we systematically introduce various metal atom-decorated carbon nanomaterials to determine how to enhance the electrochemical performances of Li-S and Li-Se batteries by inhibiting the polysulfides/polyselenides shuttle phenomenon as well as catalyzing them toward quick redox conversions. We also briefly include the drawbacks and bottlenecks of this kind of material when used in Li-S and Li-Se batteries
