Title:
APPARATUS FOR RECYCLING WASTE BATTERIES
Document Type and Number:
WIPO Patent Application WO/2024/058603
Kind Code:
A1
Abstract:
The purpose of the present invention is to recover valuable metals by heating objects located inside a work unit. The work unit heat-treats the objects under a mixed reducing gas atmosphere in which log(PCO2/PCO), the logarithm of the partial pressure of carbon dioxide divided by the partial pressure of carbon monoxide, is -2.15 to 2.5. According to the present invention, carbon emissions during the heat treatment of waste batteries are prevented, and the heat treatment efficiency can be maximized by actively controlling the gas environment in which carbon monoxide and carbon dioxide are mixed.
