▎ 摘  要

NOVELTY - The method involves sandwiching conductive acid-resistant material with the positive electrode material of the lithium ion battery as the cathode of the electrode system. The conductive acid-resistant material is sandwiched with the negative electrode material of the lithium ion battery as the anode of the electrode system. The sulfuric acid solution is added to the electrode system. The solid-liquid separation is performed after the reaction. The method does not include the processes of pulverizing, ultrasonically oscillating, roasting, sieving, magnetically separating, and grinding the positive electrode material and the negative electrode material of the lithium ion battery. The conductive acid-resistant material includes platinum, gold, palladium, lead, titanium, aluminum, copper, stainless steel, graphite, glassy carbon, carbon fiber, graphene, carbon cloth and carbon felt. USE - Method for simultaneously recycling positive and negative electrodes of lithium-ion batteries using multi-layer electrode structure. ADVANTAGE - The method provides higher economy, lower tank pressure, better effect, and realizes the simultaneous recovery of positive and negative electrode materials. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation of a particle size distribution of activated carbon powder recovered (Drawing includes non-English language text).
