Recycling of lithium ion cells and batteries

A new process for recycling Lithium ion cells and batteries is described. In order to gain maximum value, the process aims to recover every component from the cell. In contrast with existing recycling processes, the AEA Technology process operates at ambient temperatures. There are three main stages; electrolyte extraction, electrode dissolution, and cobalt reduction. The technology is currently in development, with a demonstration unit linking the process stages together in active operation. Based on the projected quantities of lithium ion batteries available for recycling in the next few years, there is a significant market opportunity for a successful technology.
