To address this issue, researchers have developed a liquid-liquid solution that produces small lithium batteries, such as those in mobile phones and other mobile devices, before being discarded. The technology is designed to avoid interfering with land reclamation procedures.
For larger units, such as those in electric vehicles or local PV storage systems, they have developed an output technology that collects energy and feeds it into the grid to activate the battery compartment.
By 2021, 6.6 million tol cars will be sold worldwide, while EV imports are expected to reach 23% by 2030, accounting for the largest fraction of the global battery demand.
Given this rapid increase in the use of Li-ion batteries and their subsequent disposal, CSIRO researchers say they are ready to help industry partners transition to the more reliable management systems they have designed.
