Tackling global demand for lithium one string at a time

Use this story and the accompanying summary slide to provide real-world context for 14–16 learners studying crystallisation and separation techniques. US researchers have designed a technique that uses strings to significantly speed up the evaporation of lithium salts from brine. This greener approach could help meet growing global demand for the metal, which is needed for electric vehicle batteries and grid storage, as the world moves towards electrification and zero-carbon energy.
