Thermally assisted efficient electrochemical lithium extraction from simulated seawater

•Rapid and selective Li extraction from heated simulated seawater•Temperature and concentration-dependent electrochemical Li extraction behaviors•Enhanced kinetics rather than thermodynamic shifts control Li extraction•A low electrical energy consumption (11.3–16.0 Wh mol−1 Li)•Freshwater (13.2 kg m−2 h−1) production from coupled thermo-osmosis
