Abstract: This disclosure provides a waste battery thermal desorption treatment system. The waste battery thermal desorption treatment system includes: a rotary kiln, having a feed port, thermal desorption cavity, heating cavity, discharge port, and first exhaust port; a dust removal apparatus, including a housing with a gas inlet port and a second exhaust port, and a dust removal structure disposed in the housing configured to collect impurities in a gas exhausted from the first exhaust port; a condenser, in communication with the second exhaust port, to condense an electrolyte constituent; and an adsorption column having a defluorination agent for dry defluorination on remaining constituents in the gaseous exhaust. This disclosure resolves the problem of low recycling efficiency of waste lithium batteries in the prior art.

Abstract: This disclosure belongs to the field of battery recycling technologies, and specifically, to a battery recycling method. An example battery recycling method is disclosed including: performing split processing on a battery to obtain a metal shell and an electrode assembly, where the electrode assembly includes a roll core or a lamination; and recycling the metal shell. According to the recycling method in various embodiments of this disclosure, the battery is not wholly crushed, but the battery is split to obtain the metal shell and the electrode assembly. In other words, the metal shell obtained through recycling by using the recycling method in this disclosure is not crushed, thereby ensuring reusability of the metal shell.
