The Li–S battery is an intriguing and chemically rich system, with operating principles that differ considerably from the state-of-the-art Li-ion batteries. The chemical complexity arising from the solvation of the cathode active material and its subsequent dynamic behavior with the Li-metal anode presents an exciting challenge to researchers across the globe.
Single lithium ions migrate back and forth between the electrodes of lithium-ion batteries during charging and discharging and are intercalated into the active materials. During discharging, when lithium is deintercalated from the negative electrode (copper functions as current collector), electrons are released, for example.
