Beschreibung
Zusammenfassung:	The invention discloses a method for recycling a lead-containing grid of a waste lead-acid battery through self-gravity contact electrolysis, and belongs to the technical field of recycling of lead through electrolysis. An anode is a conductive container with a hole; lead grid granules activated and cleaned in advance are put into the conductive container with the hole and a lead-containing solution and are electrolyzed; the lead grid granules are dissolved at the anode gradually, and electrolytic lead is obtained at a cathode. The lead recycled by the method has the purity of 99.999% or more; the corresponding energy consumption for electrolyzing each ton of lead is generally 15-45kWh/ t; the recycling method can be carried out continuously and circularly, so that industrial requirements can be met.
