How cellulose fibres grab lithium from seawater – Most of the global lithium is produced from brine using large evaporation ponds, which negatively impacts ecosystems and limits production. Chen and colleagues report an interfacial evaporation method for swift and selective extraction of lithium from saline water using twisted cellulose fibre crystallizers. The cover image depicts the mineral crystals formed on the fibres.
