In article number 1900671 , Feng Pan and co‐workers investigate the short‐circuiting mechanism of garnet Li 7 La 2.75 Ca 0.25 Zr 1.75 Nb 0.25 O 12 (LLCZN). Instead of propagating uniaxially from one electrode to the other in a dendritic form, metallic lithium is formed within the solid electrolyte. It is found that the grain boundaries of LLCZN provide electron pathways, which allow Li + to be reduced by electrons into metallic Li.
