How can a battery recycling system be improved?

Specific measures include establishing a comprehensive modular standard system for power batteries and improving the battery recycling management system, which encompasses transportation and storage, maintenance, safety inspection, decommissioning, recycling, and utilization, thus strengthening full lifecycle supervision.

What is battery recycling?

Battery recycling is a downstream process that deals with end-of-life batteries of different types and health conditions. Many established battery-recycling plants require a standardized presorting process to distinguish spent LIBs, as direct recycling reduces the efficiency of recovering valuable metals.

What is pretreatment in battery recycling?

Pretreatment is the initial and vital step in the battery recycling process, which converts batteries from compact, solid units into fractured parts and fine particles for subsequent refinement. Primary pretreatment processes include sorting, discharging, disassembly, and crushing. 2.1. Battery sorting

Which recovery process is most widely used in battery recycling?

As shown in Table 3, hydrometallurgy is the most widely used recovery process. This depends on the original intention of battery recycling process design, which is to utilize and resynthesize waste LIB materials to achieve a circular economy.

What is lithium-ion battery waste management?

Lithium-ion battery (LIB) waste management is an integral part of the LIB circular economy. LIB refurbishing & repurposing and recycling can increase the useful life of LIBs and constituent materials, while serving as effective LIB waste management approaches.

How to recycle Li-ion battery active materials?

Typical direct, pyrometallurgical, and hydrometallurgical recycling methods for recovery of Li-ion battery active materials. From top to bottom, these techniques are used by OnTo, (15) Umicore, (20) and Recupyl (21) in their recycling processes (some steps have been omitted for brevity).
