What is waste lithium-ion battery recycling?

Waste lithium-ion battery recycling technologies (WLIBRTs) can not only relieve the pressure on the ecological environment, but also help to break the resource bottleneck of new energy industries, thereby promoting the development of a circular economy, enhancing both sustainability and economic efficiency [ 8 ].

Can lithium be recovered from battery recycling plants?

There has been a steep increase in the global demand for lithium, and developing an economic supply of lithium is thereby important for battery industries. This study presents a new method for recovering lithium in wastewater from battery recycling plants, in which a considerable amount of lithium (∼1900 mg L −1) is discarded.

How effective is the lithium recovery system?

Repeated operation of the electrochemical system demonstrated highly efficient and reliable lithium extraction and organic material removal from wastewater. After the lithium recovery system operation, a lithium-rich solution (98.6 mol% lithium among cations) was obtained, and the organic pollutants in the wastewater decreased by 65%.

Can lithium ion batteries be recycled?

Lithium-ion battery (LIB) is widely used in electric vehicles with the advantages of small size, high energy density, and smooth discharge voltage. However, the subsequent recycling as well as reuse of waste LIBs poses new problems due to the toxicity and contamination of cobalt, nickel, copper, manganese, and organic carbonates [ 4, 5 ].

Are lithium-ion batteries safe?

Lithium-ion battery, an important component of electric vehicles, has received widespread attention for its advantages including small size, high energy density and smooth discharge voltage. However, their potential safety and pollution issues are becoming prominent and must be properly handled.

What is a lithium recovery ratio?

Lithium recovery ratio C31. The lithium metal in the product as a proportion of the lithium metal in the waste LIBs. Cobalt recovery ratio C32. The cobalt metal in the product as a proportion of the cobalt metal in the waste LIBs. Wastewater recycling ratio C33. The amount of reused wastewater recycled as a percentage of total discharge wastewater.
