Wetting property of Li metal with graphite

(Science China Press) Compositing two classic anode materials, graphite and Li metal, has shown promising performance to go beyond the traditional Li-ion batteries. However, it is generally accepted that Li metal wets graphite poorly, causing its spreading and infiltration difficult. Here researchers show that graphite can either appear superlithiophilic or lithiophobic depending on the local redox potential via a fundamental study on the wetting property of Li metal with different kinds of carb...
