Abstract
Herein, well-dispersed cobalt phosphide (CoP) electrocatalysts embedded in nitrogen-doped carbon (CoP@NC) were developed as an iodine host for zinc iodine batteries. Benefiting from the high electrical conductivity of the carbon matrix and the strong interaction as well as the efficient electrocatalytic activity of CoP with iodine species, the host achieved rapid iodine conversion while effectively suppressing the formation of polyiodides and zinc dendrites.
