Li–S batteries: Firing for compactness
Nature Energy, 2017Conventional Li–S batteries have a non-compact cathode structure containing low areal loading of active materials. Now, a strategy of burning Li foils in a CS2 vapour is presented, which leads to the formation of highly compact Li2S nanoparticles as a lithiated sulfur cathode, offering promising battery performance.

Outline of Li–S Battery Project
2021In this project, Li–S batteries have been investigated by a team comprising 12 principal investigators. In particular, we focused on developing Li–S batteries with sparingly solvating electrolytes for cathode active materials. Prior to the start of our project, the dissolution of the discharge products of sulfur (lithium polysulfides: Li2Sx, x = 8 ~ 2)
