Li-ion batteries

Lightning fast conduction

In the intensive search for higher performance Li-ion cathode materials the spotlight is firmly fixed on Li-rich compounds. Now, a strategy utilizing a fluorinated, disordered LiMn2O4 spinel structure shows how ultra-fast Li-ion diffusion and high energy density can be achieved with Mn and O redox.
