“…17 Many efforts have been made to mitigate or suppress dendrite formation: most researchers have focused on the electrolyte, modication of ZnO and additives in the electrodes. 9,18 A large variety of inorganic additives, such as Ca(II), 19,20 Bi(III), [21][22][23] In(III), [24][25][26] and Ba(II), 27 have been added to zinc electrodes, and it was found that they can suppress dendrite formation on zinc electrodes to different extents. In addition, organic additives, such as surfactants with pi electrons on fused rings 28 , polyaniline and polypyrrole, 29,30 have also been adopted to stabilise the zinc electrode.…”
