Abstract: An anode for a lithium rechargeable battery includes an interphase layer made of phosphorus-doped graphitic carbon nitride. The anode includes a lithium metal layer and an interphase layer provided on the lithium metal layer, in which the interphase layer includes phosphorus-doped graphitic carbon nitride. The interphase layer induces the lithium growth in a plane direction and reduces the growth of dendrites and decomposition of an electrolyte.
