Abstract

Outside Back Cover: The cycling stability of lithium sulfur batteries is severely affected by the uneven deposition of lithium ions and the shuttle of polysulfides. Due to the different diameters of polysulfides and lithium ions, MOFs with appropriate pore sizes can achieve selective transport of different ions. In the work of doi:10.1002/idm2.12143, Zhou et al. report an ultra-thin and crack-free ZIF-8 film modification layer using ALD technology, achieving homogeneous lithium ion deposition and effective inhibition of polysulfides. Just like the net in the picture, it can catch large fish and release small ones.
