| Abstract Scope |
Pyrometallurgical approach has been widely applied to the recycling of spent Li-ion batteries. However, one of its drawbacks is the greenhouse gas generation, making it crucial to utilize the produced CO2. This study aims to develop a high-temperature recycling process by utilization of CO2 to assist the reduction of metal oxides contained in the battery’s cathode. The proposed idea includes three steps of pyrolysis, consisting of (1) binder removal, (2) separator gasification, and (3) cathode reduction. The binder removal will liberate cathode fines from its bearing foil and generate CO2 which then can be reacted with other parts of spent batteries, such as the polyolefin separator. The reaction between CO2 and the separator will produce CO gas which then can be utilized to reduce the cathode fines to its metallic forms. The results of this study are valuable for enhancing the application of pyrometallurgical route in the Li-ion battery recycling. |
