Nickel ferrocyanide counter electrode

Membrane-free Li extraction

A transition metal ferrocyanide electrode fabricated via a novel in-situ polymerization asynchronous conversion method, exhibiting nearly doubled K+ insertion capacity after hydrophilicity improvement, enabling membrane-free selective Li+ extraction from geothermal water when paired with a FePO4 electrode, with stable cycling.
