Lithium–sulfur batteries are considered potential high-energy-density candidates to replace current lithium-ion batteries. However, several problems remain be solved, including low conductivity, huge volume change, and a severe shuttle effect on the cathode side, as well inevitable lithium dendrites anode side. Rare earth compounds, which play vital roles in various industries, show latent capacity hosts or interlayers tackle inherent of lithium–sulfur application rare compounds has not been reviewed so far, despite they showing obvious advantages for tuning polysulfide retention conversion. In this mini-review, we start by introducing concept providing background information earth-based materials. main body, explore interlayers, then discuss types each. Finally, offer an outlook existing challenges possible opportunities using
