Abstract

With the increasing number of portable electronic devices and electric vehicles consumption, it is estimated there is a rapid growth of rechargeable lithium ion batteries market. With the lifetime of 5-8 years for the lithium ion batteries. In the long run, it is predicated a large amount of spent LIBs will be retired, imposing huge pressure on environmental pollution control and resources exhaustion. The effective recycling or regeneration of the spent LIBs can efficiently alleviate the environmental burden but also decrease the waste generation of valuable metal resources. Here, we propose a Co3O4 based composite materials through hydrometallurgy and sulfidation process. The regenerated materials in this study exhibit high catalytic activity in alkaline solution with a Tafel slope of 49 mV dec-1. This results obtained from this study illustrates a green and facile recycling approach for Co3O4 based composite materials from the spent lithium ion cathode materials for catalytic reaction.
