The invention discloses a power lithium ion battery all metal recycling and cyclic utilizing method. Waste lithium ion batteries serve as raw materials, the disassembling-screening and roasting procedures are adopted for separating battery pole powder from other parts in the batteries, then, acid leaching is conducted, and leaching liquid containing cobalt, nickel, manganese and lithium is obtained; through extraction, separation and purification of cobalt, nickel, manganese and lithium are achieved, battery-level cobaltous sulfate, nickel sulfate and manganese sulfate are obtained, then, lithium-sodium separation is conducted, and lithium carbonate and sodium sulfate products are obtained through lithium deposition and concentration. The power lithium ion battery all metal recycling and cyclic utilizing method is green and efficient, danger waste generation is avoided, and large-scale production can be achieved. Various valuable metals are systematically recycled from the waste powerlithium batteries, according to the recycling rates, Co is larger than 95%, Ni is larger than 95%, Mn is larger than 98%, Li is larger than or equal to 94%, and the water cyclic utilization rate is larger than 95%. Nickel sulfate liquid, cobaltous sulfate liquid, manganese sulfate liquid and lithium carbonate obtained through the power lithium ion battery all metal recycling and cyclic utilizing method meet the battery level product standard.
