High performance MBene substrate for improving the MnO2 cathodes of aqueous Zn-ion batteries† Slow kinetics and instability seriously hinder the development of MnO2 cathodes in aqueous Zn-ion batteries. Herein, an emerging 2D material MoB-based MBene was used as the MnO2 matrix.

Core–shell oxygen-deficient Fe2O3 polyhedron serves as an efficient host for sulfur cathode† Herein, an oxygen-defect-rich core–shell Fe2O3−x@C polyhedral sulfur host was prepared, which effectively promoted electrochemical conversion and further inhibited the “shuttle effect” in lithium–sulfur (Li–S) batteries. Fe2O3−x@C@S provided a high initial capacity of 1395 mA h g−1 and a low attenuation of ∼0.067% per cycle.
