Document Type and Number:
WIPO Patent Application WO/2023/149017
Kind Code:
A1
Abstract:
Provided is a heat treatment method for lithium ion battery waste, said method comprising: a battery heating step for heating lithium ion battery waste while supplying an inert gas in a heat treatment furnace 1; and a gas combustion step for sending gas that is produced in the heat treatment furnace 1 to a gas combustion furnace 2 and combusting said gas in the gas combustion furnace 2, wherein in the battery heating step, when the lithium ion battery waste is heated while supplying the inert gas in the heat treatment furnace 1, the gauge pressure in the heat treatment furnace 1 is maintained in the range of -0.20 to -0.01 kPa.
