Can lithium-ion batteries be recycled?

A Critical Review of Lithium-Ion Battery Recycling Processes from a Circular Economy Perspective. Batteries 2019, 5 (4), 68, DOI: 10.3390/batteries5040068 Lv, W.; Wang, Z.; Cao, H.; Sun, Y.; Zhang, Y.; Sun, Z. A Critical Review and Analysis on the Recycling of Spent Lithium-Ion Batteries.

Are ASSB batteries safe to recycle?

For Li–metal and Li–S batteries, the reactivity of the materials and side reactions will bring up some additional safety concerns during recycling. Less safety concerns need to be addressed when dealing with ASSBs. However, mechanical handling and hydrometallurgy will be more difficult compared to current state of the art batteries.

Are batteries safe to recycle?

Newer approaches like direct recycling are highly dependent on the efficient sorting of battery types based on a convenient battery labelling with regard to the cell chemistry. For Li–metal and Li–S batteries, the reactivity of the materials and side reactions will bring up some additional safety concerns during recycling.

Can recycled lithium-ion batteries prolong the end-of-life?

Addressing these threats, recycling spent LIBs could be considered as the ultimate solution to prolong the End-of-Life (EOL) of lithium-ion batteries. This solution allows us to return valuable materials back into the value chain and close the loop of LIB life-cycle, realising circular economy. Figure 1.

What is the potential recycling process of lithium-ion batteries?

The potential recycling process of lithium-ion batteries (LIBs) Figure 1 points out that the recycling process of spent LIB mainly includes deactivation, pre-treatment, and recovery. These entire processes aim to reduce the scrap volume, separate battery components, enrich valuable metals, and eliminate hazardous waste released to the environment.

How are batteries recycled?

The recycling process achieves recovery rates of up to 95% and involves a chemical precipitation method. There are several companies that apply a combined approach. Nickelhütte Aue GmbH (Germany) or Umicore (Belgium) use a hydrometallurgical treatment after smelting of the batteries to recover metals from the alloy (matte).
