Small current recovery battery

How can batteries be recycled?

The current recycling process involves dismantling the batteries to recover valuable raw materials and resynthesizing them. However, this process is time consuming, costly, and energy intensive. It is therefore important to reduce the number of processing steps involved in recycling.

What is battery capacity-recovery technology?

Our solution to this problem is a battery capacity-recovery technology that involves injecting reagents, which is the shortest recycling route that does not require dismantling.

Do batteries need remanufacturing?

With the rapid increase in lithium (Li)-ion battery applications, there is growing interest in the circulation of large quantities of spent batteries. However, existing recycling systems require not only several processes for recycling itself but also remanufacturing processes, which require increased energy consumption.

Why is it important to recycle batteries?

Recycling spent batteries is important to ensure their sustainable use. As we shift toward electrification, the number of spent batteries will increase dramatically. The current recycling process involves dismantling the batteries to recover valuable raw materials and resynthesizing them.

Can a recovery reagent injection be used for regenerating batteries?

However, existing recycling systems require not only several processes for recycling itself but also remanufacturing processes, which require increased energy consumption. Here, a recovery reagent injection is proposed for regenerating spent batteries.

Why does battery capacity increase if no recovery reagent is used?

Even in the simulated capacity-degraded battery containing only new carrier Li + ions, the capacity does not increase with repeated cycles in the absence of the recovery reagent, indicating that the addition of a substance with both electrons and carrier Li + ions is responsible for the reaction driving force for capacity recovery.
