Li–S Batteries: Ultrathin MXene Nanosheets Decorated with TiO 2 Quantum Dots as an Efficient Sulfur Host toward Fast and Stable Li–S Batteries (Small 41/2018)

In article number 1802443 , Xiao‐Dong Zhu, Yi‐Tao Liu, and co‐workers report unique solvothermal growth of TiO 2 quantum dots (QDs) on ultrathin MXene nanosheets. Through remarkable synergies, the resulting TiO 2 QDs@MXene nanohybrids exhibit significantly improved long‐term cyclability and rate capability as a sulfur host, disclosing a new opportunity toward fast and stable Li–S batteries.
