Theoretical investigation on the dendrite suppression and desolvation promotion effect of the coating material on the Zn metal anode for aqueous zinc-ion batteries: case study of oxide coating

Multiscale simulations uncover how oxide surface govern Zn 2+ desolvation and diffusion in aqueous zinc-ion batteries. While SiO 2 promotes ultrahigh desolvation, TiO 2 , Al 2 O 3 , and CoO balance desolvation efficiency with low diffusion barriers.
