Waste lithium ion battery processing method and device, computer equipment and storage medium

The invention relates to a waste lithium ion battery processing method and device, computer equipment, a storage medium and a computer program product. The method comprises the steps that waste lithium ion batteries are directionally and orderly arranged in order through a vibration disc, and the waste lithium ion batteries are conveyed into a flame-retardant liquid tank at the bottom of puncture equipment; under the condition that the waste lithium ion battery is immersed in the flame-retardant liquid, puncturing the waste lithium ion battery through puncturing equipment; placing the punctured waste lithium ion battery in a sealed collecting barrel for a preset time length; and crushing and sorting the waste lithium ion batteries which are placed for the preset time length. In the whole treatment process, an automatic conveying mode is adopted, the arranged waste lithium ion batteries are immersed in flame-retardant liquid to be punctured, and sealed shelving is performed for a preset duration after puncturi
